When PROOF Research joined Lawrence Barrels in 2012 they acquired 15 years of experience in manufacturing precision steel barrels. PROOF manufatures stainless steel barrels 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 the material of choice because it has the following characteristics: Excellen Mfg: Proof Research, Inc

When the added velocity of a longer barrel needs to be preserved, but the desire for additional weight reduction remains, barrel fluting serves as an excellent solution to help shave away unwanted bulk. Criterion fluted AR-15 barrels are designed to ensure maximum concentricity and consistent dimensions throughout the full length of the bore. Eight flutes are machined around the circumference of the barrel to the front and rear of the gas port. Each flute is polished to smooth jagged edges while retaining a sharp appearance.
