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/.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. |
