NLA AR10 MLOK Handguard Specifically designed to match our Ascend 308 upper receivers, we machine our AR10 Mlok handguard from aluminum extrusions in house and hard coat anodize to mil-spec tolerances. A solid, Nitride coated, billet steel barrel nut ensures a solid and stable mount to your receiver. Whether you shoot for competition, hunting, or competition, Next Level Armament designed our handguards for comfort and strength without added weight. Each handguard features MLOK attachment points on both sides and the bottom of the handguard. *Due to a slight variation on upper style with the Ascend 308 uppers, there may be a slight step between this handguard and other brand traditional DPMS Low Profile uppers.* Length : 15' Inner diameter: 1.6875'
