Modular aluminum handguard snaps into place like a plastic handguard with no gunsmithing required. Features T-marked MIL STD 1913 Picatinny top rail that lines up with flattop uppers for a clean, monolithic look. Includes three sections of moveable polymer rail for accessory mounting flexibility. Large ventilation holes help air circulate and keep overall weight down to a half-pound or less, depending on the length. Five anti-rotation QD sockets give many sling-mounting options.
