Griffin Armament XM Linear Compensator with Grenade ring- Built using dimensions from the original Colt print and aesthetic geometry from an actual MAC-V-SOG XM177-E2. Manufactured from 17-4 SS, weighing 7.2 ounces per set of linear compensator and Grenade ring, the Griffin XM Linear comp is an actual functional muzzle device, not a slug of bar stock with a hole in the middle that resembles the XM Moderator.
Per NFA we built the XM Linear Comp as a linear compensator, so the baffling specific to the original part is not present and the XM Linear comp is designed new from the ground up as a functional retro muzzle device for your retro builds.
Pictured is a 12.37" barrel 16.19" non NFA pinned and welded build on a Griffin Armament XM Linear comp.
This product requires an A1 Armorers tool, Griffin Armorers tool, or thin 5/8" wrench for installation. Torque to 30-35ft lbs and visually check alignment prior to firing.
