Yankee Hill Machine Colt Carbine 2-Piece Handguard Assembly, Quad Rail, Black Anodized - YHM-9670-C

This 2-piece handguard assembly replaces standard plastic handguards on Colt AR-15 carbines with carbine-length gas systems and fixed front sight gas blocks. Constructed from lightweight aircraft-grade aluminum with hardcoat anodized matte black finish to military specifications, it features a 4-rail Picatinny design and measures 6.625 inches in total length. Installation requires no gunsmithing—simply remove existing handguard panels and insert these in their place; the bottom rail removes easily to accommodate accessories like grenade launchers and flare launchers.
