Noveske Varmint Barrel with Headspaced Bolt AR-15 5.56x45mm 20 Medium Contour 1 in 8 Twist .875 Rifle Length Gas Port Low Profile Gas Block Stainless Steel

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 and M4 extended feed ramps. Each barrel is shipped with a pinned, low profile gas block and barrel extension.

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.
