Free-float handguard with four MIL-STD 1913 Picatinny rails is engineered specifically for AR-15s with gas piston systems. The Piston Omega Rail features additional internal clearance for weapons with piston systems and a removable top rail for access to piston components. Installs in minutes with absolutely no permanent modifications to weapon. Two-piece design allows installation without removing the gas block, using only a common flat-head screwdriver and the included hex key. Tighten the four Allen-head screws against the barrel nut with the hex key to eliminate movement and align the extended top rail with the receiver rail for an exceptionally long expanse of accessory mounting space. Mil-Spec model fits AR-15s with carbine-length gas piston systems from Adams Arms, Ares Defense, LWRC International, and Primary Weapons Systems. Large Diameter model has additional internal clearance to accommodate Bushmaster, CMMG, and Patriot Ordnance Factory (POF) carbine-length gas piston systems. Plenty of ventilation cuts keep barrel cool and minimize weight—perfect for short tactical carbines where every ounce saved improves speed and maneuverability. Rail slots are indexed with white letters and numbers for precise positioning and remounting of accessories. Receptacles for push-button QD sling swivels in the side rails have built-in rotation limiters. Precision CNC machined from 6061 T6 aluminum and mil-spec Type 3 hardcoat anodized for added strength and a rock-hard surface that resists wear and scuffing.
