When PROOF Research joined with Lawrence Barrels in 2012 they acquired 15 years of experience in manufacturing precision steel barrels. PROOF Research's stainless steel cut-rifled 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.
These barrels are shipped ready to be fitted, chambered, threaded and crowned by a qualified gunsmith.

Best barrels in the game
The barrel I got was concentric down to .0002, nice and tight towards the crown. Can’t get better tubes than these.
