Noveske EXTRA THICC SPR 6mm ARC AR-15 Barrel 18" DDF Contour Rifle-Length .9375 Gas Block Stainless Steel with Headspaced Bolt

Noveske's Stainless Steel AR-15 Match Barrels feature their Noveske Match Chamber, designed to offer outstanding accuracy. 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. Each barrel is shipped with a pinned, low profile gas block and barrel extension. The Disruptive Deep Fluting (DDF) is an external barrel structure designed to significantly reduce primary (blast compression and expansion) and secondary (sinusoidal resonance) wave events in barrels, improving accuracy, reducing heat, and extending barrel life.
