GG&G HK USP Full Size Slim Line Picatinny Light Mount

The HK USP has its own light rail, and many lights and lasers are made for a Picatinny rail instead. This GG&G Slim Line (M3/M6) adapter clamps onto the existing rails of a full size USP and gives you a Picatinny section.

It fits tight against the trigger guard, so rear rocker switches can be worked with the trigger finger or the support hand thumb. The fit is tight enough to hold zero on a laser. Machined from solid billet aluminum.
