Improves Handling & Reduces Heat Buildup

Tubular free-float forearm is made of lightweight, high-strength carbon fiber to reduce heat transfer to the shooter’s hand during sustained fire and provide excellent handling characteristics. Precision-made, aluminum barrel nut rigidly clamps the forearm to the upper receiver. Generous porting on some models enhances heat transfer while reducing weight even more. Rifle model fits rifle-length gas systems and is available in three styles: Target solid-surface tube; Ported/Railed with 28 cooling ports, three 3½" Picatinny rails that can be repositioned for specific needs, and an 8½" top rail; Ported/No Rails with 34 cooling ports for maximum heat dispersion. Mid-Length model has 6 cooling ports, three 3½" and one 5½" removable Picatinny rails. DPMS 308 is designed specifically for DPMS-pattern AR-style .308 rifles and includes four Picatinny rails.
