Proof Research Seekins Precision HIT Carbon Fiber Prefit Barrel 223 Remington 20" Sendero Contour 1:8" Twist 4 Groove

Overview

The Proof Research Seekins Precision HIT prefit barrel features a 20-inch length, a .223 Remington chambering, a Sendero contour, and a 1:8-inch twist with 4-groove cut rifling. Built in-house from double-stress-relieved 416R stainless steel, the barrel is wrapped in aerospace-grade carbon fiber using a helical pattern. This advanced carbon fiber construction provides superior longitudinal thermal diffusivity, allowing the barrel to dissipate heat rapidly, cool faster, and maintain match-grade accuracy and durability over extended strings of fire.
