Noveske Lightweight Crusader AR-15 Barrel 5.56x45mm NATO 12.5" Lightweight Contour 1:7" Twist Stainless

Noveske's Stainless Steel AR-15 Match Barrels feature their exclusive 5.56 Match Mod 0 Chamber, designed to offer outstanding accuracy with both 5.56x45mm NATO and 223 Remington ammunition. Composed of 416R stainless steel that's hardened to 30 RC, the bore is given improved polygonal rifling that slightly boosts projectile velocity and reduces the speed of the bore's erosion, meaning superior accuracy retention that outlasts that of barrels with conventional rifling. All Noveske match barrels have a bead-blasted satin finish, M4 extended feed ramps, and are threaded at the muzzle for the addition of flash hiders, muzzle brakes and/or sound suppressors.
