RT-3 Prism Sight is rated out of 5 by 4.
Rated 5 out of 5 by Theo JC from Great in every way. Exceptional sight by any standards. Clarity is top shelf. Ocular and objectives are nice and generous in diameter. The photo below doesn't do justice. The recticle may seem smaller at first, but a few minutes of acclimation solves that. But again, the clarity is tops. Reticle brightness in sunlight was usable, but the low settings are very well choosen for lower light conditions. Overall, the low weight, smaller form factor, excellent sight picture and price will hopefully make this RT3 a legend.

Rated 4 out of 5 by Skulltoy from Great idea, forward thinking instead of rehashing I have tried a couple things on my AR builds over the years. Decided to try the fad of LPVO's. While they have all been pretty good I just can't get over adding 14-20 oz of scope and another 3-6 oz with a mount. I tried various combos and got a LPVO setup down to low 20oz. That is still a lot of weight on top of a lightweight 16" AR. I have tried various Prism sights 3-4x, the weight being less, I found I actually preferred this set up. When I saw this announced at SHOT 2020, I was waiting for some initial reviews, nothing............. Then I caught a posting on AR15 forum where someone took the plunge and loved it, then another, all reporting good initial thoughts. So I snagged myself, I got to say that I am surprised this has not been tried before. This is absolutely PERFECT! A 3x prism sight the size of a common micro Red dot, a wide field of view, super lightweight, and great glass for the price range. The reticle while maybe a little smaller that I have used it other 3-4x scopes it was the same size as the Steiner I had tried. 5.56/7.62 BDC reticles don't always work as using different combos of ammo the BDC is useless, you got to learn what you shoot and how it is hitting at what ranges. I combined this 3x with fixed 45 degree sights, makes a perfect all around performer. I don't understand people expecting to take their 5.56 past 500 yds. At 3x this is perfect for hunting distance at 50-100 yds, or perfect for hitting a man sized target up to 400 yrds. BURRIS is the only one that has a 3x prism this size, weight and features. You need to get the word out BURRIS! My negatives which are not that negative, just little peeves. I have 3 things that would make this a 5 star product; 1.) make the reticle only light up the center dot and horseshoe, 2.) I hate buttons, give me a rotary dial, 3.) give me the ability to change mounts or do a quality QD mount instead.

Rated 5 out of 5 by Vinegarjoe27 from I’ve been waiting years for this optic The first optic I bought for my carbine length AR was a LPVO and instantly regretted the decision. It had its advantages but the size and weight made my rifle feel unwieldy even when I mounted it on my 20” AR. I wanted a low power fixed optic with illumination for red dot like utility, 5” or under in length without the depleted uranium weight of a prism scope. Such an optic didn’t exist so, I resigned to buying a red dot, but the thought of eventually adding an ungainly magnifier turned me off to the whole idea. Then I fortunately stumbled across the rt-3. I just returned from the range and I am left wondering why Burris isn’t marketing this more. The glass is clear enough that I stopped noticing it, FOV is amazing, the reticle naturally centers the eye, and most importantly, the weight of the rt-3 is imperceptible. Rifle balance was the same as when shooting with irons. Plenty of eye relief to aim comfortably with stock fully extended. Burris should be singing it’s praises to the hills. It’s superior to the vortex gen 2 prism because of its more forgiving eyebox. Yes, I mounted it all the way back and had to remove my rear sight, but I’m also not on duty or in theatre. Even if I was I’d still feel confident with this little beauty. Thanks for making my dream carbine optic

Having no etched reticle how would this do for people with astigmatism?
These have an etched glass reticle. No problem.

Is there any after market mount compatibility for the rt-1. Looking for something with lower 1/3 cowitness and qd.
They'll work with any of the micro mounts from Aimpoint for the T-1

What is the battery life of this optic? Does it have an etched reticle?
The RT-1 does not have an etched reticle. The battery life depends on the brightness, but likely somewhere around 1,000 hours.

Can the RT-1 handle being mounted on the slide of 45ACP pistol? I’m thinking of mounting this on a 1911 for bullseye shooting. Thanks Brian
They are not designed for use on a reciprocating slide. For a handgun I would highly recommend the Fastfire III or Fastfire IV. The RT-1 is rated to .50BMG but have not been tested on slides. I imagine this could cause issues with the mounting hardware as they are intended for a static receiver/rail mount.

Will the high base mount offer a 1/3 sight co-witness? and is the low mount full co-witness?
The higher mount it comes with we refer to sometimes as the "AR" mount. That one will be absolute cowitness. The other one is just a lower mount that will fit a variety of firearms not needing that sight height. The low mount works great on AK variants, MP-5s, and similar. I have an RT-1 on a PTR9C and I'm using the low mount. It offers the perfect cheek weld with the A3 stock or collapsible SB brace.
