DEZ Arms' custom machined match barrels are made from 4150 chrome-moly vanadium steel manufactured in the USA. Barrel are head spaced with M4 (nickel boron) feed ramped extension installed, pre drilled gas port hole with parkerized finish. Barrels are particle tested, air gauged, concentrically cut and muzzle threaded 5/8” x 24. 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. The 11 degree crown, polished chamber and lapped bore makes the difference! Our pulled-button rifling produces a superbly accurate bore diameter with uniform rate of twist.

The match barrel is machined to rigid specifications

Optional flash hider and bolt (no carrier) (NOT INCLUDED: sold separately)
