Glock RMR Cutting

Gunsmith Services


We can machine the cut directly in front of the factory sight which allows the install of Dawson Precision co-witness sights or we can machine the RMR cut over the existing iron sight dovetail.

This page is for information only.  No need to prepay for gunsmithing services.  Services and any shipping charges (if applicable) will be invoiced when the work is complete and ready for pickup or shipping.

Product Details

Pilot Mountain Arms is now machining Glock slides to mount a Trijicon RMR to your pistol. The RMR cut will result in a co-witness with suppressor sights (not included). We can cut your slide for any slide mounted red dot sight (Trijicon, Leupold, Vortex, etc).

We machine indexing posts for the sight to index on. The posts fit precisely into the bottom of the sight to prevent it from moving due to recoil forces and help to maintain zero if you have to remove the sight for some reason. 4-40 threads are precision milled into the indexing posts to ensure precise centering and the highest quality threads. The posts also give the 4-40 screws more thread engagement. Sight cut depth: .120", includes two 4-40 x 3/8 Torx T-10 screws. Estimated turnaround on machining services is 3 weeks.
