About Our Barrels
The custom machined match barrels used in RGUNS rifles and uppers are made from 4150 chrome-moly vanadium steel manufactured in the USA. Each 5.56 NATO barrel is properly head spaced with an M4 feed ramp extension installed.

Barrels are particle tested, air gauged, concentrically cut and, where threaded, muzzle threaded -28 R.H. twist to accept flash hiders/suppressors, stressed relieved, turned on center to prevent accuracy robbing distortion when the barrel heats up, and hardened to 26-33 Rc giving the barrel a long life. 

Each barrel has an eleven degree crown, polished chamber and lapped bore, as well as a pulled-button rifling,  producing a superbly accurate bore diameter with uniform rate of twist. Fluted models feature unique fluting designs to improve rigidity and aid in barrel cooling.
