Precision machined from heat treated stainless steel for superior durability, the M4-72 can withstand the extreme heat of combat conditions without being subject to rapid erosion. Available with an advanced Ionbond® high temperature CrCN coating (matte black), or stainless steel in-the-white (satin grey). Accu-Washer™ Muzzle Alignment System required for installation.
