RT-3 Prism Sight is rated out of 5 by 3.
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.

Is there a sun shade extension for this?
There is not a sunshade for the RT-3.

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.

I have a 20 ga. Winchester NWTF SX3 and I am trying to mount a Burris RT-1 sight but the cantilever mount does not match the supplied base. Can you suggest an adapter to fit ?
After looking at the shotgun you have, you will need a weaver to picatinny adapter for it to fit.

Since it states Prism, does that mean it’s a prism scope and not a true red dot? Does it have an adjustable diopter to adjust for vision differences and astigmatism?
I called Burris with this exact question and I was told it is a "prism" sight but does not have an etched reticle. Still looking for a real life review.

Is this a red dot you can shoot with both eyes open? Or will the magnification affect ones ability to do so?
Yes, you can use this sight with both eyes open. It won’t have a continuous FOV like a 1x, but you can and should still shoot with both eyes open.

Can iron sights be used by aiming through the RT-1? And can the RT-1 be used in conjunction with a magnifier?
Hello, Yes to both questions! The RT-1 is compatible with the Burris AR-Tripler and you can use it to cowitness with iron sights.
