Noveske SPR AR-15 Barrel 6mm ARC 18" SPR Contour 1:7" Twist Stainless

Noveske's Stainless Steel AR-15 Match Barrels feature 416R stainless steel that's hardened to 30 RC. The bore has polygonal rifling that slightly boosts projectile velocity and reduces bore erosion, improving accuracy retention compared to barrels with conventional rifling. All Noveske match barrels have a medium contour, bead-blasted satin finish, M4 extended feed ramps, and are threaded at the muzzle for the addition of flash hiders.
