More Information:

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/.223 barrel is properly head spaced with an M4 feed ramp extension installed.

Barrels are particle tested, air gauged, concentrically cut and muzzle threaded ½ -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.
