Proof Research Stainless Steel Bolt Action Barrel - 106396:

Proof stainless steel barrels are manufactured with an absolute commitment to extreme accuracy and quality. Starting with double stress-relieved 416R stainless steel, a pre-hardened chromium stainless steel ideally suited for use in precision, match-grade rifle barrels. 416R was specifically designed by engineers in collaboration with barrel makers and rifle manufacturers to provide the consistency, high quality and durability the firearms industry demands..

Advantages of 416R Stainless Steel Rifle Barrels

• Excellent machinability for gun drilling and reaming
• Exceptional polishability for uniform lapping, a must for bore accuracy
• A homogeneous microstructure which responds to heat treatment
• A uniform hardness along the length of the bar
• An optimum combination of high tensile strength along with the toughness to withstand typical chamber pressures encountered during firing
