The IMI Defense USGI-type replacement for your carbine’s factory-original handguard is made of tough, fiberglass-reinforced, injection-molded polymer that delivers superior impact and abrasion resistance. The ridged gripping surface and top/bottom vent holes retain the weapon’s authentic military look, while an internal heat shield of lightweight aluminum protects your hand from barrel heat. M4 Mid model is available with standard-issue single heat shields for extra insulation during sustained rapid or full-auto fire. All models fit AR-15/M16/M4 with Mid-length gas system.
