-Aimpoint ACRO, Trijicon SRO, Trijicon RMR HD - approximately lower 1/4

- Due to the variation in suppressor tube diameters and optic heights, we do not guarantee that this sight will protrude over your particular setup, nor are we able to maintain a database of all possible height/fit variations.
Fitting is usually not required, but the QPQ/Melonite finish is harder than a normal steel file. If the sight is too tight and needs to be filed, use a diamond file or hone (see Brownells.com), as files will slide right off the surface.

Pretty much perfect…
Not sure what else one could want in a RMR backup rear sight. Appears to be made well. The only thing I can even come up with as a not perfect is the amount of material on the “ tail” sight doesn’t fill the dove tail. Does come with a set screw but would like to see just a bit more material. Great lower 1/4-1/3rd cowitness on a MOS w/ RMR. Exactly what I was looking for at a good price point.

Fit my Glock 43x
I was worried it wouldn't fit my milled 43x slide. 100% co witness with my Holosun 507k and direct milled slide.

Glock MOS sight
Excellent quality sights. I always check here first to see if they make sights for my pistol before buying elsewhere. I’ve installed several 1911 sights, Glock sights and M&P sights from 10-8 performance. Always excellent quality you know what your getting and seem to require the same fitting which is welcome. No surprises when fitting the sights. Thanks for making an excellent product.

Glock MOS rear sight
Installed smoothly and works great with tall 10-8 front sight

Rear sight
Sight is very high quality. Fitment was very tight. I paired it with the black front and am very happy with them. They just stick up just enough to co witness with an RMR, no more than necessary. Will definitely purchase more 10-8 sights in the future.

Glock Suppressor/Optic/MOS Rear Sight
I have this sight installed on my Glock 40 (10mm Auto) with a RMR and they work great. Perfectly co-witness with the RMR and the sight picture is excellent.

I CAN SEE
I love fiber optic over orange dot. It’s quick, it’s brighter, Iran’s it’s just awesome.

Great match for RMR optic
Installed this sight and the black .315 Extra Tall front sight on my G19 Gen 4 MOS. Installation was easy (used a sight pusher) and the sight combo gives a great lower 1/3 picture in the Trijicon RMR's window. Very pleased with the purchase.

easy to see
I have an astigmatism. This sight makes it easier to pick up front sight and not blurr my target
