BSF Barrels Zermatt TL3, SR3 Carbon Fiber Prefit Barrel 6mm GT 26" 1:7.5" Twist

Overview

The BSF Barrels prefit carbon fiber barrel for Zermatt TL3 and SR3 actions is chambered in 6mm GT with a 26-inch length and a 1:7.5" twist. Featuring a match-grade 416R stainless steel core, the barrel is jacketed in a roll-wrapped carbon fiber sleeve under tension rather than wrapped directly, leaving air gaps that allow the barrel to cool rapidly and prevent delamination. The carbon fiber material shares the same expansion rate as stainless steel, and machined vents in the sleeve assist with heat dissipation while maintaining superior stiffness, a vibration-dampening effect, and a lightweight profile. The barrel is double stress-relieved with 6-groove button rifling and an 11-degree target crown.
