The Proof Research Stainless Steel Bolt-Action Competition Barrel (brand part number 123317) is a 26-inch .223 Remington barrel built in a competition contour for short-action bolt guns. Machined by Proof Research from stainless steel, this barrel carries a 1:7 twist rate suited to heavier .223/5.56 bullet weights common in competition loads, and it is threaded 5/8-24 for a standard muzzle device or brake. The extended 26-inch length helps squeeze extra velocity out of the cartridge, a real advantage in speed-sensitive precision disciplines.
