Product Information

Noveske's Stainless Steel AR-15 Match Barrels feature their exclusive 6.8mm SPC Mod 1 chamber (.100 freebore), designed to offer outstanding accuracy and reliability. 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 medium contour, 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 installed, as well as a gas tube and barrel extension. This match barrel also includes a factory-headspaced bolt, guaranteeing proper fit and lockup.

Technical Notes:
  • Noveske Match Stainless Barrels use a proprietary 1" long gas block that comes installed from the factory. Standard AR-15 front sight bases (1.9" long) are NOT compatible.
  • The 6.8mm SPC Mod 1 Chamber closely follows the dimensions of the improved 6.8x43mm SPC Spec II chamber by providing .100" of freebore. This allows for the use of either standard or high pressure 6.8mm SPC factory ammunition.
