HK M320 Retention Clamp

Starting at $191.00

30-Day Manufacturing Warranty

The Heckler & Koch M320 Retention Clamp was born during a request from one of our Military partners needing an on-body, Soldier Systems retention system for the LMT M203 stand alone launchers. We wanted to make the HK M320 Retention Clamp similar to our battle-tested Rattler MCX clamps we did for a different Military partner. We knew this style of clamp would be successful with the addition of a strap or buckle. We are using squadron material with a small, 1/2″ buckle to clasp the system. The bulk of the retention comes from the 0.125″ thick KYDEX that is vacuum formed into the ribs of the grip on the 40mm tube. The HK M320 Retention Clamp also comes together at the trigger guard to prevent any sliding of the launcher system, in the retention clamp itself.

– Designed for HK M320 Launchers with left or right side mounted
– 0.125″ thick KYDEX
– Squadron with 1/2″ Buckle for Retention
– Blade Tech Tek Lok for on body Mounting
– Hole pattern matches Blade Tech Molle Lok Hinges for Molle compatibility
– Hard plastic bushings for minimal flexing of the clamp
– Flared shoulders for easy of insertion of the launcher
