The Aim Sports M4 Handguard (brand part number MT021) is a 6-inch, carbine-length quad rail built as a drop-in upgrade for a basic carbine handguard. Machined from aircraft-grade aluminum, it is compatible with most carbine-length direct impingement gas systems, and the two-piece design clamps on without any gunsmithing. All four rail faces follow the standard Weaver/Picatinny 1913 pattern, so lights, lasers, grips, and other accessories mount the same way they would on any other Picatinny-compatible handguard.
