Noveske Afghan Barrel Features The Noveske Afghan Barrel is machined from 416R stainless steel and cut with a 1 in 7 inch twist rate matched to stabilize the long high ballistic coefficient bullets favored in 6mm ARC. Its Disruptive Deep Fluting design removes mass along the barrel s length while preserving the stiffness a precision barrel depends on for consistent accuracy. A hand-polished Noveske Match chamber and extended hand-polished feed ramps work together to smooth feeding and tighten group sizes. Finished in a bead blasted silver coating the barrel resists glare while standing up to field conditions. A mid-length gas system paired with a pinned low-profile gas block positions the gas port correctly for this 14.5 inch barrel length giving smoother cycling than a mismatched gas system would allow. Threaded 5/8x24 at the muzzle the barrel accepts common 6mm ARC compatible brakes and suppressors without an adapter. Each barrel ships individually serialized along with a headspaced DLC-coated bolt matched specifically to its gas system and chamber dimensions. AR-15 builders working in 6mm ARC will find this barrel a complete precision-matched package for a dedicated long-range build.
