SI Rear Sight Rail Adapter for Glock
Ratings & Reviews
Pretty awsome, fallow my install directions though!
Was sceptical of this design.
But after having it on the weapon with the charge handle, it's actually pretty stout and reasonable especially if you dont have access to a cnc or ability to drill/mill your slide.
I also enjoy the fact that they put the dots on the back of the rail you can paint and CO-WITNESS the iron sights while a red dot is on! Super cool design.
Except do not tighten the big back screw first.
Do the dovetail set screw and level set screws and tighten back screw last
