Description

The HK USP Compact carries that proprietary HK rail up front, which means most of today's flashlights and lasers won't drop right on. This GG&G Slim Line mount solves that. It's a three-piece adapter that clamps over the factory USP light rail and gives you a true Picatinny / MIL-STD-1913 surface to work with, opening the door to a whole catalog of modern accessory heads on a pistol that otherwise gets left behind.

What the Slim Line M3/M6 Mount Fits

This one is built specifically around the HK USP Compact and plays nicely with popular light and laser bodies including the Streamlight TLR-1, TLR-2, and the Insight/L3 M3 and M6 units it's named after. It keeps a low, slim profile so your setup doesn't turn into a brick, and it sits tight against the trigger guard on purpose. That fit means rear rocker switches on your light or laser stay within reach of your fire control finger or the thumb of your support hand, which is exactly where you want them under stress.

Built From Billet, Made to Hold Zero

GG&G machines this mount from solid billet 6061-T6 aircraft grade aluminum and finishes it in a Type III hard coat anodized matte black. It's featherweight at right around three quarters of an ounce, so you're not adding any real heft to a carry-sized pistol. More importantly, it clamps down tight enough to retain zero on a laser, which is the whole point of running one. A dab of blue thread locker on the clamp screws during install is smart insurance so nothing walks loose after a few range sessions.

A Practical Upgrade for an HK Classic

The USP Compact earned its reputation for being reliable and easy to run, and this mount lets you bring it into the modern lights-and-lasers world without buying a new gun. Installation is straightforward with basic tools, and once it's on, you've got a stable home for your weapon light or aiming laser. It's proudly made in the USA, which is what folks have come to expect from GG&G.

Frequently Asked Questions

What handgun does the GG&G Slim Line M3/M6 mount fit?

It's designed specifically for the HK USP Compact family. Users have reported clean fits on the USP Compact in .45 and other calibers. Keep in mind it's built for the Compact rail, not the full-size USP.

What lights and lasers will work with this mount?

The adapter gives you a standard Picatinny / MIL-STD-1913 surface, so it accepts a wide range of compact accessory heads. It's named for and works well with the Streamlight TLR-1, TLR-2, and the Insight/L3 M3 and M6 units. Anything sized for a standard Picatinny rail should clamp on fine.

Will this mount hold a laser's zero?

Yes, that's a core part of the design. It clamps tightly onto the factory USP light rail so it stays put and retains zero on a laser sight. Adding a bit of blue thread locker to the screws during install is a good idea to keep everything locked down through repeated range use.

Is the GG&G HK USP Compact mount hard to install?

Not at all. It's a straightforward clamp-on design that attaches to the existing USP light rails with basic tools. Most folks have it mounted and ready in just a few minutes.
