Built for serious precision shooters, the Impact / Lone Peak 6mm GT Buschman Pre-Fit Barrel delivers competition-ready performance with the convenience of a pre-fit design. Chambered and finished in-house by 2-Time World Champion and PRS Champion Austin Buschman, these barrels are engineered for shooters seeking exceptional accuracy, consistency, and reliability from their Impact Precision or Lone Peak Fusion action.

Designed specifically for Impact 737, NBK, and "FZ" serial Lone Peak Fusion actions, each barrel arrives ready to install and head straight to the range. Chambered in the highly regarded 6mm GT cartridge, this pre-fit combines outstanding ballistic performance with reduced recoil, making it a favorite among PRS, NRL, and long-range competition shooters.

Manufactured from premium stainless steel and finished in a polished stainless appearance, the barrel features a competition-proven CRB Comp contour and a fast 1:7.5 twist rate optimized for today's heavy-for-caliber 6mm projectiles. A 5/8x24 threaded muzzle allows easy installation of suppressors, muzzle brakes, and other precision shooting accessories.
