Good Quality, Holds Zero
Lightweight and rock solid. Comes with a torx wrench and a spare mounting bolt in case you strip one. It looks good on the rifle and doesn't move under recoil or from moderate bumps. Good quality finish holds up well. Excellent mount for Bushnell TRS 25 and Primary Arms mini red dots. With Magpul MBUS sights, the 0.83 inch riser gives you a nice lower 1/3 cowitness. The sights sit below the dot in the lower third of the glass when looking at the dot alone. The 1.0 inch riser will just barely cowitness, but you can only see the very top of the front sight blade when using the iron sights with MBUS and the aforementioned red dots. The 1.0 inch riser was too tall for me, couldn't see enough of the front sight post, and much of area around the post is blocked by the emitter with the TRS 25. I've not tried the 0.75 inch riser, but I suspect it offers an absolute cowitness with the TRS / PA / MBUS setups. Pro Tip: If your iron sights are zeroed in, you can easily zero in your red dot without firing a single shot. Just look through your iron sights in perfect alignment while adjusting the elevation and windage of the red dot so that the dot sits on the top center edge of the front sight post. Make sure you are looking through both front and rear sights in perfect alignment when you do this. This works regardless of the height of the mount or type of cowitnes, and some people think this is cowitnessing. It is not the same as an absolute cowitness, which might explain the conflicting info on riser heights and cowitness. All correctly zeroed iron sights and red dots will appear to be cowitnessed when looking through the iron sights, regardless of the height of the riser. However, with a lower 1/3 cowitness, the dot is also visible above the sights when you move your eye above the iron sights.

QUALITY MOUNT; true ⅓ lower co-witness! (Paired with AT3 RD-50)
Love this mount! The looks, how compact it is, the light-weight, the finish. Seems super durable & quality machined (a lot of "extra" material has been removed to keep it as light as possible without compromising it's integrity). The logo is nice as well, the sizing & that it's etched. It has 2 mounting screw instead of just 1 like some mounts do. **MOST IMPORTANTLY: I'm using it on an AT3 RD-50, when I purchased that sight I opted for the 1" riser that stated it would be ⅓ lower co-witness, it was *not (using Kriss USA lo-pro poly BUIS). I couldn't see my irons through the sight at all, with the UTG mount on the same optic, it is a true ⅓ lower co-witness, fits the optic perfectly, & has an additional mounting screw. The only "con" which I can't really even put in that category is the fact it must be mounted with a tool/wrench intead of a QD mount (which I know they offer those options, which is why I can't knock it).

Excellent for the price - perfect height & light weight
Works as advertised, was a breeze to install, and holds fast. I used blue loctite on it, so I'm not worried about it coming loose. Love the .83" height for co-witnessing. Overall, it's a great budget riser. I use mine with a Bushnell trophy micro-dot.

Good for the money.
I bought this riser as a mount for a Bushnell TRS-25 red dot, which seems to be the best choice for budget optics. I went with the .83" for absolute co witness of iron sights, but ended up putting the whole assembly on a 300 Blackout pistol that doesn't have irons yet, so I could take it to the range and shoot it. The good: It's inexpensive, and light. The machining and finish were fine. The bad: The screws keeping the mount on the pic rail worked loose under the recoil. After 40-50 rounds fired, the whole assembly was in danger of falling off the pistol. After I got home, I backed the screws out, and applied some temporary (blue) loc-tite. I think it should work, but I haven't tested it since. I would recommend using loc tite before heading to the range.

Surprisingly good
A surprisingly sturdy and well built riser. Metal feels great, and fits very snug onto my airsoft rifle. Comes with torx screws as an added bonus. Would recommend for anyone looking for a no frills riser.

its a quality piece for the money
Paid 9 smacks for it in dec 2024 on sale, sold and shipped by amazon . a well machined lightweight piece , it's a picatinny stacker , not aimpoint mount . its very low pro in design , makes my other mounts look bulky , The supplied hardware is GTG . notice the 5 star reviews are 80% that is usually a good indication of quality .. i would buy again and have referred product to others .

I'm actually quite surprised with the quality of this riser for the money. It's small, lightweight and feels very sturdy. The 2 star headed screws are solid (wrench is included). The 0.83 gives you perfect co-witness with the Bushnell trs-25 on AR platforms. I use to go with the cheaper UTG riser which is also nice for the money, but this one is worth the extra 10 bucks or so. The 2 screws design is better and the mount is much smaller, slimmer and nicer looking. The TRS-25 combined with this riser gives you quite a decent optic for the money that really can't be beaten. Next step up would be a holosun micro or sig romeo 5, but they go for more than twice the price of this combo.
