I Tested And Ranked The Best Red Dots For AR-15 In 2024

There are a lot of red dot sights on Amazon to choose from. I've gone through thousands of reviews and rounded up the best options for the money.

best ar15 red dot sight

FYI, prices and ratings are accurate as of time of writing.

1. Sig Sauer - Romeo5 1x20mm Red Dot Sight

best ar15 red dot sight


Highlight: 10 illumination settings (8 daylight, 2 NV) for visibility in all light conditions.

Helpful review: "I received this in the factory sealed box, and with the factory tamper proof seal in tact! The sight came boxed with the Mounting Key, Lens Cloth, Battery, 2 Mounts, Lens Cap, and Instruction Sheet. This is a very nice sight, easy to mount, clear red dot.
A few things that's important to know about the optic:
(1) Read over the instruction sheet. Don't just assume that because you've had these types of sights before you'd know how this one would work. You wouldn't!
(2) Yes! The sight has an auto-off after 120 seconds of "No Motion" when auto-motion is ON. So, yes! Remember to use this option in order to avoid unnecessary battery drain. If you've read the instruction sheet it informs you that the sight also has an actual Power Off and Power On option. To use this option you only have to hold down on either the + or - button longer than 1 second, and the same thing to power it back on.
(3) Some reviewers are reporting the sight not working, etc... This is a result of one of couple of things. When you first install the battery, you will not be able to see the red dot until you turn up the brightness, so click the + button (Don't Hold It Down At First, Just Click It) 3 or 4 times. If you still don't see the dot, assume the sight is in its Powered Off Mode and push and hold either the + or the - button for 1-Second to actually turn the sight on, then click the + (plus) button a few times until the dot becomes bright enough to see.
(4) Another possible problem that could happen is with installing the battery. Mine had a safety peel off sticker that HAS to be removed. When you peel these off, it leaves adhesive (glue) on the battery. So it's possible that you'd leave enough of it to cause a certain loss of battery contact. Make sure when you peel the sticker off from the battery that all the adhesive is cleaned off of the battery itself.
Caution! the brightness adjustments in either direction ISN'T A PUSH & HOLD operation!!! It's momentary CLICKS! That means that the brightness setting isn't a constant veritable. It's in CLICKED STEPS! Caution! Holding down for more than one second on either the Plus or the Minus button actually turns the optic sight OFF (totally powering it down) meaning that just clicking the brightness buttons (Plus or Minus) will not do anything until the optic sight is "Turned Back On"!
So what's the bottom line on the misinformation of this optic? All I can say is that it has some higher level electronics then the standard red dots. It's not rocket science, but it's cause for a lot of these being returned and the reason for a lot of the low rated reviews. It's NOT only "Auto Powered Controlled". It can be Turned Off, and it can be done so by accident. PLEASE read over the instruction sheet FIRST before you box this sight up and return it. It's such a great quality that it deserves that much attention.
Now let me make this clear. This review is from a 64 year old AR-15 (5.56 NATO) gun owner! I can say that the sight responded well to adjustments! It seems to be holding ZERO very well with what ammo I've fired so far! And, again, it has very clear optics! Having the turret adjusting bits built onto the turret caps works very well! There is no issues with the quality or function of this sight that I can find, but I'm thinking that the same sight upgraded to the larger tube and lenses might be NICE! but it would be larger and it cost more! Very Nice for the money!" — Mark Watters

2. Vortex Optics - Venom Red Dot Sight

best ar15 red dot sight


Highlight: The top load mechanism allows you to easily change the battery (without removing the sight).

Helpful review: "After months of looking for a red dot sight for my rifle, I settled onto this one. I had been debating between Vortex, EOTech, Trijicon and AimPoint, and what sold me on this sight was the design and the price.
First, let's break down the competition. I was originally considering the EOTech 512 Holo, but soon found out that they have a class action lawsuit against them for that optic due to issues with accuracy in areas of high heat or extreme cold. I live in AZ, and right now the average temperature is about 116 F (46 C) and I did not want my optic to become compromised in the desert heat. Onto the Trijicon... unfortunately the MRO was out of my budget but it is still a very good optic (and if I had the money I would definitely consider picking one up). Sadly this was the case for the AimPoint optics as well. I asked a friend who works for the NE State Patrol what optics he preferred, and he said that he and his family only use AimPoint. For a State Patrolman to fully trust a product... it must be good, but unfortunately I do not have $400 to spend on a 1x optic, so I had to pass.
This was where this little guy came in... Vortex has many options for 1x sights like the Strikefire, for example. However, I wanted something different. The Venom is precisely what I was looking for, just in a smaller package than what I expected.
When I was looking at it, people were saying how well it fits their AR-15s and other rifles, and so I bought it. The price was right, the design was right, and the Vortex warranty didn't hurt either.
When I received the sight, I was dismayed because I realized it was a mini red dot. I think it was more designed for AR's with free float barrels, shotguns, and handguns rather than AR's with A2 posts. So I hopped on Amazon to see what a riser would cost me and I was taken aback by the price of the Vortex Quick Release Riser Mount at $100. Needless to say, I found a better option.
Once I got everything squared away and lined up, I took it to the range and sighted it in. The adjustments were quick and easy, and I was able to sight it in for 50 yds. After a few thousand rounds and a few trips in the desert heat, this optic has held up well and looks pretty decent to boot.
If you don't have more than $250 to spend on a sight and don't want a scope, this is a good optic. And you really can't beat the price from Amazon. Vortex will always provide you with their 'No Questions Asked' lifetime warranty. So yes, I'm very pleased. I saved some money, and highly recommend this red dot." — Ryan Grobe

3. CVLIFE - JackalHowl Red Dot Sight

Top-rated: 68 ratings

best red dot sight for the money


Highlight: Fully sealed and nitrogen-filled, making it anti-fog and IPX7 waterproof.

Helpful review: "Hey everyone, I have a new red dot sight, and we need to talk about it. I have the CVLIFE JackalHowl red dot. This red dot comes with two mounts; the one that is attached to the optic is a co-witness riser for Picatinny. I am not a fan of all the look-through mounts; it's one more thing I don’t want to learn. If this red dot were mounted on a rifle or carbine with the old school iron sights, maybe I would actually learn that, but with the world of flip sights, I want to look through the optic and use the flip-ups as a window to see the open irons.
This red dot cannot be used on a handgun unless it’s a massive handgun like the Desert Eagle or the old Ruger Redhawk, made with the rail milled into the top strap. I wish my shotgun had a picatinny on the receiver so I could give this a try on that, for no reason other than I think it would be cool to do it. I put it on my AR15, this is a good fit for the red dot. My AR is a 50 Beowulf, and I don’t want a scope anywhere near my eyeball or eyebrow.
The adjustment turrets on this red dot are tucked away under some threaded plugs, I will call them. The reticle is a red dot, 2 MOA-sized sight. The reticle is a shake awake style, and it works like a champ, with no hesitation or lags coming back on when I barely move the gun. The adjustments and switch buttons are on the top of the sight, two little push buttons. The reticle has 10 levels of brightness, I could not tell much difference between one or even two button pushes, but I can tell you that the red DOT is very bright and easy to see.
The sight is made out of high-grade aluminum, and the lenses are coated with anti-fog. The box says it is waterproof, and I did not throw it in the sink to check because I did not think to try that out.
The box set has everything you will need to mount to the gun, the hex wrench, etc. The box has two nickel-sized batteries, so you will not run out of batteries. Speaking of battery life, the box says 50000 hours of battery life. I do not have that many hours left to life to check, but I can tell you that I tried to leave it on for half an hour to see if that would draw the battery down, but the reticle turns off in four minutes if the gun does not move.
The red dot has no magnification factors and unlimited eye relief, and that is great for a high-recoiling rifle or shotgun because it can mount mid-rail, like the scout scope rifles, and keep that away from the eyebrows. I did find that you need to keep the check weld like a scope when moving the rifle. If you move your head, you may lose the dot, and then you must reacquire the sight and sight picture.
I really enjoyed shooting with this red dot; it is very light; for a two-hand gun, you will not notice the weight at all. The profile is compact, and it will not make a big impact on the weapon's size to fit behind the seat or in a tight scabbard. I may drill and tap a picatinny rail on the lever action I take when I go out to the sticks in the RZR, so it does not take up space, and it is quick to use.
Now, down to “brass tacks,” as they say, would I recommend it? Yes. Would I buy another one? Yes, I will buy another one. Mounting a Picatinny rail to older guns for ease of use as my eyes don’t keep up with their need to focus on iron sight will be a difference maker." — Gary Anderson

4. Burris - FastFire III 8 MOA Dot

best red dot sight for the money


Highlight: Tool-less wind age and elevation adjustments.

Helpful review: "I spent a half day sighting in and plinking at golf balls at the range and I am VERY happy with this red dot reflex. I'll provide a more complete review when I've spent more time testing it with a sand bag rest at longer ranges. Right now, the variations in shot placement definitely reflect the quality of the shooter and not the sight!
This package includes the rail mount base plate with thumbscrew and hardened alignment pins (perfectly tight fit between my flat top AR and the Fastfire III); Torx mounting screws with captive external tooth lock washers (no Loctite needed, with 1 spare screw/lockwasher thoughtfully included in case you lose one); Torx wrench to install the 2 semi-permanent screws; jeweler's screwdriver (nonslip matte finish tip, swivel top plastic handle, much better than needed for adjusting windage and elevation); battery; dust cover/sun shield (not pictured, nice bonus); soft fabric storage pouch for the sight + base + cover; and very minimal mouse-print instructions that experienced shooters won't read anyway. Get your reading glasses and take 1 minute. Before you tear up the battery cover like I did.
Things I'd do differently next time:
1. Don't bother with a bore sight. I suspect the factory settings were just fine. I spent most of the day undoing the elevation and windage adjustments I'd made at home based on an admittedly cheap bore sight. Ammo is too expensive and rare to waste like I did.
2. Buy a Flat Top Riser Scope Mount. This sight is SO low profile I couldn't get a good cheek weld with muffs on, the red dot seemed to be at the very top of the lens. At times I thought I'd accidentally turned it off, or maybe the battery had died. No, just shooter error. Use plugs alone, or raise the sight about ½” -3/4" with a riser rail.
3. Do NOT use the tiny jeweler's screwdriver to reinstall the battery cover. Yeah, it comes off with one... Use a big fat tip screwdriver that fills the slot. Or maybe a penny or nickel. The body of the sight is hardened aluminum; the battery cover may or may not be hardened, but you will definitely tear up the screwdriver slot on the battery cover if you get so excited about your new toy that you just can't bother making a trip to the garage for the correct size screwdriver. Buddy, listen to me, there is NO SENSE reading this review then repeating my mistake. You just spent $250, now treat it like a quality optic worth at least that much. Thank you.
The soft rubbery black rectangular pushbutton on the left side is nearly flush with the sight and rotates through 5 settings: Automatic brightness, Hi, Medium, Lo, and Off. The pushbutton does not give any audible and only minimal tactile feedback, so watch the dot.
I was shooting on a bright sunny day, standing in both shade and full sun, shooting in the afternoon toward the Sun and was able to find the dot even on the lowest setting. The Automatic brightness setting seemed to provide an even wider range of brightness than the manual settings, if that's possible.
The bonus dust cover/glare shield cut the dot brightness just a bit (as expected) so you might experiment leaving it on if you find the dot still too bright for dim light as other reviewers on other websites have claimed. The dust cover has a generous relief cut to fit around the pushbutton but my fat fingers couldn't always press the button far enough with the cover on. I may take a Dremel to the relief cut to make the opening bigger, I suspect most of you won't need to.
The elevation and windage screws seem to have a very wide range of adjustment. They do not have audible or tactile clicks, which should be unnecessary anyway. You cannot adjust these with bare hands (i.e., without a small screwdriver like the excellent one enclosed) but I cannot imagine needing to make frequent adjustments.
NOTE that if you max out one adjustment screw all the way up or down, you cannot move the other. Don't force the second adjustment screw, just back off the first adjustment screw a tiny bit. Then use plugs not muffs. Or buy a sight riser. Because you didn't need to max out the elevation screw in the first place.
I've owned a cheap (<$150) red dot reflex sight before, with plastic body and cheap mount. Don't waste your money on a lesser sight. This is a very high quality optic designed to withstand 1000 Gs, with hardened aluminum body and mount. If you need something even tougher, buy the optional Burris mount that surrounds and protects the entire Fastfire III." — Jim Cox

5. Sig Sauer - Romeo-MSR Red Dot Sight + FREE Magnifier

best ar15 red dot sight


Highlight: Ultra-compact combo kit.

Helpful review: "Obviously not a holographic, it's a reflex. I knew that ahead of time, just clarifying for anyone wondering. Either bad Chinese translation or false advertising.
When viewing indoors, at first I thought it was bunk, there was a red halo all over the edge of the sight. Must have been the indoor lighting though. I have it on ar15. Once it was mounted and outside it was very clear and almost spot on accurate before any adjustments. Barely adjusted a couple clicks. I didn't quite shoot 100 rds (pricy right now), but it appears to be holding zero. Plenty bright for day use.
The magnifier eye relief is a bit close at 65mm as advertised, it is clear and works like a short 3x scope. I think overall it is a decent quality product from China and good for the price.
Everything about this is badass. I zeroed it to my already zeroed iron sights. Went out into the woods, gave the KOD to 1 Deer, and 4 squirrels without really having to adjust it at all. Set up some paper targets about 100 yards away and had a perfect grouping with the magnification. This optic is well worth the buy. Never stray away from SIG my fellow red dot users.
The Romeo MSR is an awesome budget friendly tool good out to 100yds by itself. I have verified! The Juliet magnifier makes far objects more identifiable and acts like a mini low power scope. Flipped to the side for closer shots it's out of the way. I like mine to flip LEFT so I reversed it and the mount. I can use the Juliet magnifier as a separate spotter with the left eye when needed or just flip it in combo with Romeo and Bang! Only issue I ran into was running out of rail at the rear to reduce eye relief. I have to collapse the stock 2 notches. An adapter would solve that but I'm good with it as is." — Aaron Birch

6. Aimpoint - PRO 2 MOA with QRP2 Mount and Spacer

best ar15 red dot sight


Highlight: 30,000-hours (3 years) of constant-on battery life.

Helpful review: "With this Aimpoint PRO you truly do "get more than you pay for." I switched to it from an Eotech 512.A65 because I hated the 65MOA ring on the Eotech.
It seemed to always cause problems with my vision for both eyes open shooting. I also found that the Eotech was a little low for me when mounted straight to the top rail. I may have needed a riser for it, but the fact that I was not having much luck with the reticle and the height issue was not really worth me getting a riser to see if that might help. To me the reticle being compatible with your eye, shooting style and brain is the most important part of the optic.
When you get this it is simply packaged in a plain white cardboard box. No fancy tupperware or pelican case for it. Simply a plain white box with some stickers on it. Inside it some run of the mill foam. So why just a box? Well, this was designed to be purchased and used by police departments. When Aimpoint first introduced them they were only available for purchase by law enforcement. Most police departments, at least the ones I have been associated with, could care less what comes of it, they just want a product that works.
The cardboard box also helps to keep the overall cost of the product down. The boxes are literally meant to be tossed (or recycled if that's how you swing) when the optic is taken out and mounted. Also inside the box is an allen wrench for taking the riser off, shorter screws for using without the riser installed and one 1/3N-Cell battery.
First impressions of the mount and optic together is "that is one HUGE knob..." It is much bigger than it looks in the pictures, and it sticks out a fair amount. The riser actually looks nice, and of course being the gadget kind of guy I am I had to take it off to see how it would look without it in place. You quickly see that you need the riser, or you will end up with a sore neck and cheek. The torque limiting mount is actually very nice.
In the past, I have seen quite a few top rails that have been permanently damaged by over tightening rail attachments. Once you click it three times it is set, and very secure. I tend to give it a click or two whenever I pick up my rifle or get out to the range just to make sure that it is good and tight. The knob is low enough that it does not interfere with your vision, and I have yet to have it get in the way when shooting.
Overall, the mount is very well made and a wonderfully innovative design. One thing that I did do was when I reinstalled the riser after experimenting, I put some blue (242) Loc-Tite on the screws, just to ensure that the screws were not able to back out on their own. While I do not foresee this as an issue, one can never be too careful with something used as a defensive tool. I have removed this mount and optic several times to test the return to zero, and each time I have not had any shift in my zero.
Something to note, though, is that you will need to return the optic to the same rail slot in order to maintain zero, moving the optic on your rail will result in the shift. If you plan to re-index the optic on your rail you will want to go back and zero your rifle and optic again.
Pre-installed on the optic are lens covers and a battery and turret cap keeper. The lens covers are of decent quality, and appear to be of the same type as Butler Creek, but appear to be better made. The cover that comes on the rear is clear and the front cover is black. While you can get two clear covers, the combination of the clear and black will work for a shooter that leaves both eyes open. Even though you cannot see through the optic, the dot will still superimpose onto your vision and you can still use the red dot. This can be used in a panic situation where you have your rifle, and have not flipped the front cap.
One thing that I did find though is that when shooting in this way that my shots were hitting about 1" low at 25 yards. While not a huge point of impact change, if you are shooting farther that will open all the way up to 4" low at 100 yards. In a CQB situation, 1" low is not going to make a huge difference, and will still affect the desired outcome on a torso sized target.
But it is something that you want to practice and find out how much of a change in impact you will get. The cap keeper that comes with the optic is nice rubber, and will hold the caps for you. The keeper connects the battery cover and both of the adjustment turret covers. So if you are at the range and remove your adjustment turret caps they will stay attached to the optic. This is a nice feature so that you do not lose your caps. I have lost a fair share of turret caps in the past just by setting them down and then leaving without them.
The adjustment turrets are 1/2MOA per click. The clicks were a little weak, but when I switched from a screwdriver to a coin I was able to feel them a lot better. This is probably because the clicks transfer through the metal coin better than through the plastic handle of a screw driver. So I just use a coin now to make any adjustments and any of the common coins you will find in your pocket will work.
There are a total of 10 brightness settings on this optic. While four of them are for night vision devices, the other six are visible without night vision. I do find that only the last three settings are actually visible, even in complete darkness. So there are three settings that seem to be lost in limbo: they are too bright for night vision and not bright enough to be seen without night vision. I tend to use the settings at the 8 and 9 position.
With this dot I have found that you want to keep the brightness as low as you can for your situation because the brighter the dot, the more it bleeds in the dark. Also of no real use if the brightest setting, or the 10 setting. It is so bright that the dot bleeds, and it actually illuminates the outside edge of the optic around the glass.
I currently have mine sighted at 25yds for CQB/Home defense work, but have shot it out to 300yds and was consistently hitting a 4MOA gong without any problems. The best way to find a good zero for yourself is to find the furthest you plan to shoot. Once you have that information you can plug your data into a ballistic calculator and find out where the bullet will cross your line of sight. So if you want to zero to 300 yards the round you fire round will cross your line of sight at 36yds and then arc back to the point of aim at 300yds. This gives you both a close in zero and a ranged zero if you were ever to need both. This is typically called a battle zero, or BZO.
One feature that really helped to sell me on the Aimpoint PRO was that it is waterproof to 150ft (5.5ATA for the diver types).
While I do not see myself taking my rifle SCUBA diving anytime soon, the waterproof nature of this optic is a nice feature. I am in the Pacific Northwest where it tends to rain most of the year, so range time might include being out in the rain. Unfortunately that is just a fact of life here. It is a great comfort to know that in a hard rain my optic will not be damaged and will continue to function as designed.
Another positive to it being waterproof is that if it gets dirty, dusty or otherwise fouled it can be removed from your rifle and rinsed off in the sink. I have done this once after training sessions where I was running and moving around a muddy range all day. It was a great relief to know that I could wash it off, let it dry and oil everything down.
This is truly a great optic for the price. What you get with this optic is the same high end Aimpoint quality, battery life and simplicity for a smaller price tag. While there are some differences in the battery life between the Aimpoint PRO and the CompM3, they are not really worth the extra money that you end up spending in my opinion.
A battery life of 30,000 hours is pretty good and translates out to 3.7 years. The CompM3 has a battery life of 50,000 hours, or 6.2 years. When a new battery will run you $6, I couldn't justify the added expense.
Whether you are looking for a new optic with less clutter, or something with amazing battery life this optic is amazing for the price. You cannot go wrong with this as a red dot sight. It functions well, is reliable and holds a zero. Don't be fooled by the price tag, this is a solid optic that will stand up every bit as good as any other Aimpoint out there." — Steve D. Walker

7. Holosun - 510C Open Reflex Sight

best ar15 red dot sight


Highlight: 2 MOA Dot & 65 MOA Circle.

Helpful review: "I've had an RMR and a few Vortex red dots. The RMR had the dimming issue I resolved with an antiflicker plate and I loved it. The Vortex dots aren't sexy but they just work. I could punch a penny at 25 yards with both. This new Holosun, however, beats them all. The features, construction, and options put it above the competition at almost half the price. I want to share my insights with you, so let's break it down:
- Perfect cowitness with the BUIS that came with my B&T GHM9. Took a considerable amount of left to right adjustment, but the up down was dead on.
- The shake to wake feature gives it true "Go Gun" status. No fiddling with buttons to turn it on. In a bad situation you don't want to have to try to turn one on when you really need it. Pulling it out of your bag will bring it to life and you're ready to rock.
- Auto-dimming is also a great feature my RMR and Vortex dots didn't have. Once enabled you will see a noticeable and immediate difference going from dark/dim to brighter areas. Works excellent outside. The feature is disabled by holding the + button for 3 seconds. This would be ideal if you're in a shaded environment and your target is outside in a brightly illuminated area.
- In the higher brightness settings you can still see the reticle when you point it towards the sun. You won't lose your dot in bright areas.
- The reticle options are also very handy. 2moa dot will help you plink pretty far down range and the larger 65moa reticle will give you fast acquisition at closer range. They definitely both have their place. And neither the RMR or Vortex dots offered multiple options.
- The battery life is supposed to be incredible. I haven't had it long to know, but all testing has shown you'll have years between battery changes. But it does come with a spare battery tray.
- The solar feature is reassuring. Worst case scenario: you're in the field or fight and the battery dies. If you are outside in the sun, or have enough ambient light the dot will still work. If SHTF and batteries are no longer available, you'll still be able to use it.
- The quick release mount saves you an extra $150 (if you were running other dots) and allows for a perfect BUIS cowitness. Mine fit a little loose when I first installed it. I used the included tool and tightened the mount one turn and it clamped down with the force of an Amazonians thighs during Snoo Snoo. Absolutely solid now and still easy to release with the convenient latch keeper.
- The picture is incredible. The thinner profile sides and large viewing window give a natural feel and you're not chasing the dot around. No toilet paper tube EFFECT or black glob in the corner like with the Vortex Sparc AR. With boys eyes open you hardly notice the frame. You just see everything as well as a dot in your FOV.
So to sum things up, all I can say is think about the value, man... It is just a no brainer. Half the price of an MRO or RMR. More features. More rugged design. The Alamaba Arsenal torture test includes, pouring water on it, throwing it 20ft into the air and letting it hit the ground, freezing it in ice, beating on it, and SHOOTING it with a shotgun, and it still held zero. I will probably buy another one for my next Scorpion build. Can't imagine anyone coming out with a better optic for the money." — Marco Chavanne

8. Bushnell - Trophy TRS-25 1x20mm Red Dot Sight

best ar15 red dot sight


Highlight: Mounts easily on most picatinny rails, and is compatible with rifles, pistols, shotguns and muzzleloaders.

Helpful review: "Buy this optic if you are in the market for an inexpensive, high-quality, and high durability micro dot and aren't terribly concerned with the ability to use a kill-flash on it (which is probably not even necessary for the ranges this sort of optic would be useful in.
I was immediately impressed with the 'authority' of the brightness on/off switch. It feels very solid and positively clicks into each position. The image on Amazon is a bit misleading as it is missing the middle part of the mounting clamp, but I'm sure you can use your imagination to fill in that gap. The included rubber cover is nice and can be left wrapped around the sight while in use.
I mounted this optic on a UTG Medium Profile riser mount and it lower 1/3rd co-witnessed with some low-profile Troy flip sights I had on my KWA Airsoft AEG. The medium profile riser mount absolute co-witnesses with standard height irons that come on the Krytac CRB AEG. I believe these are indicative of the standard height sights on an M4/AR-15 type rifle.
I also have a Primary Arms MD-AD 2 MOA micro dot sight which uses the same mounting system as the Aimpoint T-1 & H-1 products. The brightness/on-off switch on the PA MD-AD is mushy and the brightness goes to max when in-between steps in the switch mechanism. It does, however, have hard stops at 0 and max. The Bushnell TRS-25's switch is superior even without the hard stops. The dot is also clearer in the TRS-25 in most conditions. The MD-AD has the ability to mount flip-caps and an optional kill-flash which is nice, but ultimately not necessary. The TRS-25 has a clearer picture than the MD-AD which adds a blue-ish hue to everything.
- Clear sight picture.
- Solid switch mechanism.
- Durable.
- Bright, clear dot.
- Inexpensive.
- No way to mount a kill-flash
- Would be nice if it was compatible with T-1 & H-1 mounts.
I also own a Burris Fastfire III, which is a great red-dot, but I’m not quite sure it’s worth the money in most applications. All in all, I like both for different reasons, but if you just want a great red-dot for the money, go with the TRS-25. The only time I can recommend the Fastfire, is if you wanted to put a red-dot on a pistol. Otherwise, I’m not convinced it’s worth the price difference." — Steve Holsinger

9. Feyachi - Absolute Co-Witness Reflex Sight

best ar15 red dot sight


Highlight: Fully adjustable height, brightness, windage and elevation. "Where the dot goes, so does the bullet!"

Helpful review: "Let me start off with saying I love testing these budget-friendly options of sights. I've been involved in the firearms community over 17 years now. I worked with training companies and shops. I've handled everything from bottom of the barrel, to the top of the line. I've tested several products from Feyachi, and this sight by far is an the absolute cherry of the Feyachi offerings.
I've had a few units in the past with some reticle issues. I must say Feyachi's customer service is second to none. They've always without hesitation taken care of any issues. That in itself is worth 5 stars. Pan has been an absolute pleasure deal with and their customer service cannot be beat.
This unit is rock solid. With budget optics it's tough to find something of quality. Is this an EOTech? No, not by any stretch. But It also doesn't cost $500.
I love the switch on this unit. It has the 4-way reticle selection at the rear, and a simple on and off button on the left side. I've never been into the rotating dials commonly found on these types of sights. I really like how it has the intensity control built into the button. A quick push and you can manual cycle through 6 different options. 1 is fairly dim, but 6 is super bright even in direct sunlight. You press to turn on, click to adjust brightness and press and hold to shut off. I haven't had a chance to test it, but this unit supposedly turns itself off after an hour of time if it's not moved around. I cannot confirm that as of yet.
The adjustments on the unit have a firm and positive click, and they lock solidly into place. This fit perfect on the rail system on an AR pistol, with little to no wiggle or play. The reticle selector is firm and positive when you switch through the options, but still very easy to engage. The power button is a positive click when pushed.
Overall, a very solid unit. This also cowitnesses perfectly. And the size is just about perfect. This is pretty small and low profile for what it is. I think some people may find it a bit small, but it's just right in my opinion. A lot of value in a compact package!
This unit has a small rear sight built right into the rear part of the unit. It cannot be adjusted. I thought this was just an awesome addition to this sight. It's very rare that on the unit itself there is a way to have a backup. I have not tested accuracy of it yet, but absolutely love the concept. It should help you in a pinch if you have no rear back up option.
The reticle selection. Oh, the reticle selection. Four great options. Each option is super crisp and clear. I had 4 people look at it to tell me what they thought of the clarity. 3 said fantastic, one said fuzzy. It seems very dependent on if you have an eye issues like astigmatism, or corrective lenses. No issues, but something to keep in mind.
They varying intensity is fantastic.
I love that the adjustment Allen wrenches and an extra battery are included. This comes with everything you need to throw it on, tighten it down, power it on, adjust, and clean it. Fantastic value.
I also love the lens coating. It seemed to work really well at keeping down glare, it also makes it look pretty incredible!
The unit arrive safely and well-packaged. My unit had some chipping on some of the edges. Minor for me, but I thought it was noteworthy. A dot of sharpie or black paint would take care of that in short order. My unit also has a small, almost rubbing kind of wear on one spot on the rear. The item I received was all factory sealed and in brand new condition. I could only assume it was maybe from handling in the factory. Very minor.
The hardware to attach was a little gritty. Some oil and running the screws in and out a few times took care of that quickly as well, again, not a problem, but I thought it was noteworthy. I had no issues with soft or stripping screw heads or anything like that.
The reticles, while bright and crisp, have the slightest counterclockwise lean going on. It's not perfectly vertical, just every so slightly tilted to the left. I don't foresee it being an issue, but did notice it.
Also as mentioned above. Four people looking at the reticles. Three said they were crisp, one said they were fuzzy. It seems dependent on if you have any eye issues or wear corrective lenses.
All in all, this sight is a solid purchase. This will be going on an AR chambered in 300 AAC.
If your looking for a budget optic, this is the one to buy in my opinion. With those minor nitpicks aside, this thing is of good quality, it feels solid, and the reticle selection and brightness are really stellar.
I would highly recommend this sight, and give this 5 stars. It's a tremendous value, and it has many features found on sights upward of the $90-$100 mark. It's well above its similarly-priced competitors. You won't be disappointed, and in the off chance you are, Feyachi's awesome customer service team will be more than happy to take care of you." — Alex Rowan
