Double Star's M4 carbine handguard is a snap-on, USGI-type replacement for AR-15/M16/M4 rifles with a carbine-length gas system. It is molded from fiberglass-reinforced polymer in matte black, with a ridged gripping surface and top and bottom vent holes. A single-layer aluminum heat shield in each half keeps barrel heat off the hand.
