Description

Details

These stainless steel barrels are made in-house with an absolute commitment to extreme accuracy and quality. They start 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.

416R is our stainless steel of choice because it has the following 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.

PROOF 416R arrives at your door chambered. threaded and tapered to finish-out at specified lengths. The barrels are then drilled, contoured and reamed to the bore diameter of the cartridge for which they are to be chambered. Every barrel is then cut rifled, hand lapped and inspected with a bore scope for superior quality and consistency.

They are shipped ready to be assembled onto your Ruger Precision™ Rifle by a qualified individual. The barrel will come pre-chambered in the specified caliber, threaded for the receiver and threaded at the muzzle for a supressor or brake.

Proof SS barrel on RPR nails it.Review by Will
Rating
A while back I converted my Ruger Precision Rifle, that was chambered as a 308, to 6.5 CM with the replacement of the stock barrel with a Proof Industries stainless steel 6.5 CM barrel.
There was an immediate improvement in target results. Group size reduced and consistency improved. With the stock barrel I had an occasional one hole groups for 3 shots but with the Proof barrel I have now shot three, 3 shot one hole, groups on the same target at 100 yards. Centerline to centerline the target groups were .281, .248, and .191 respectively.
Thank you Proof Industries for making such a fine product.
Best regards
Will
