The EGW H&K USP Trijicon RMR sight mount gives you a clean, reversible way to run a modern red dot on your H&K USP without permanent modifications. This 7075 aluminum mount replaces your factory rear dovetail sight, letting you install a Trijicon RMR or Holosun HS507C in minutes—and remove it just as quickly if you want to go back to iron sights. No gunsmithing, no drilling, no drama.
Built from aerospace-grade aluminum and finished in matte black hardcoat, this mount is purpose-built for the USP platform and designed to hold zero through hard use. The engineering is straightforward: drop the mount into your existing dovetail, secure it with the included hardware, and you're ready to attach your red dot. If life changes and you need to swap back to factory irons, you can—the mount comes off cleanly without any permanent alterations to your pistol.
Installation is diy-friendly. The mount ships with all hardware you need: two 6-32 flat head screws for the Trijicon RMR and a single set screw for dovetail retention. EGW includes detailed torque specs (15 inch-pounds on the red dot mounting screws) and recommends blue Loctite for a secure, non-permanent bond. A small piece of paper between the red dot and mount body makes disassembly easier down the road and keeps threadlocker off your optic.
This mount is engineered specifically for the H&K USP. It does not fit Rock Island 1911s or other platforms, so verify your pistol model before ordering.
