Airsoft USP AEP RMR Red Dot Sight Mount

thingiverse

This is an RMR Sight mount for Airsoft AEPs (only tested TM version). It replaces the rear iron-sight and mounts in each place, and the RMR then screw onto it. I used Brass Screw Inserts, specifically M2x6mm for the slide screws, and M3x3mm for the sight screws. You may want to print this fairly solid and with a strong/rigid material, like PLA or Nylon (??). I've had one printed in PETG break apart once (vertically, around the area of the RMR screw inserts), when my pistol fell on the ground, probably red-dot-first. Still under investigation!
