Lightweight, free-float, machined aluminum handguard has a unique attachment system to ensure proper alignment of top rail with receiver rail. Rotary-locking system uses a barrel nut that attaches to the barrel with the included index wrench. Handguard slides over barrel and gas tube at an offset angle, until the notched barrel nut indexes in the internal grooved channel for a secure fit. Two hex head screws lock down the handguard, and a built-in stop prevents over tightening. Vent holes let heat escape the barrel and minimize weight. White alpha-numeric designators on cross slots ensure easy repeatability of accessory positions. Standard (13" long) features full-length MIL-STD 1913 Picatinny rails at the 3, 6, 9, and 12 o’clock positions. Extreme (available in 9, 11, 13, or 15") is even lighter and sleeker with a single, top Picatinny rail, horizontal grooves for a secure no-slip grip, and additional ventilation holes to reduce weight and dissipate heat. Comes with one 4" and two 3" bolt-on rails for mounting additional accessories exactly where you need them.
