PROOF RESEARCH Competition Bolt Action Barrel .264 Cal 28", Stainless Steel

Upgrade your rifle's performance with a premium bolt-action barrel, delivered ready for custom threading and chambering by your gunsmith. Combining decades of industry expertise-including the precision legacy of Lawrence Barrels-PROOF Research manufactures high-quality stainless steel barrels engineered for extreme match-grade accuracy. Every barrel is crafted from double stress-relieved 416R stainless steel, a specialized pre-hardened chromium alloy designed specifically for ultimate durability and consistency. This premium material ensures your custom rifle build delivers the elite, long-range precision that top marksmen demand.Choosing 416R stainless steel provides the following essential characteristics: Excellent machinability for gun drilling and reaming, plus exceptional polishability for uniform lapping-a must for bore accuracy.A homogeneous microstructure which responds to heat treatment providing a uniform hardness along the length of the bar, necessary for accurate rifling to precise groove dimensions.An optimum combination of high tensile strength along with adequate toughness to withstand typical chamber pressures encountered during firing.416R arrives at the factory in long lengths and is then cut to finished barrel length. The barrels are then drilled, contoured and reamed to the bore diameter of the cartridge for which they are to be chambered. The barrels are then rifled, hand lapped and individually inspected with a bore scope.
