Product Description

Tall rear sight for clearance over suppressors and mini red dot sights (RMR, MRDS, Delta Point, etc).  Fits Glock dovetail, including Glock MOS models.  CNC machined from prehardened 4140, QPQ (nitrocarburize) finish equivalent to Glock/M&P slide.

Due to the variations in custom installations, it is recommended that you contact your pistolsmith prior to ordering to ensure that you get the correct height.  Custom M&P optic installations by ATEi and others use a Glock sight dovetail, hence the listings below.  Height is listed as total height of sight with dovetail.

  • .395" - standard height for all Glock installations (including Glock MOS) and ATEi M&P custom install with sight behind optic
    • Use with .250" tall front on M&P
    • Is .070" taller than our standard height Glock Rear Sight, and as a default we suggest trying this with a .315" front sight
    • These sights are designed around a Trijicon RMR machined into the slide. 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. Please also note that we could make sights as tall as we could cut them, but they need to fit into holsters and not catch on everything, so these are as tall as we felt were appropriate before reaching diminishing returns.


****Does NOT fit M&P CORE or factory M&P dovetail.

    I have these sights on both my go to glocks and they are nice, only thing id like to see is a slope cut on the sides (like a pyramid shape) so you can see more of the target.
