DEZ Arms' custom machined match barrels are made from 4150 chrome-moly vanadium steel manufactured in the USA. Barrel are head spaced with M4 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.

YOUR choice of fluting: Twister or Straight Flute. Our unique fluting designs improve rigidity and aid in barrel cooling. The pulled-button rifling produces a superbly accurate bore diameter with uniform rate of twist. The match barrel is machined to tighter specifications producing a tighter fit for greater accuracy. This barrel uses a mid length gas tube, mid length hand guard, .750 dia. gas blocks, and front sight (not included).

*Nitro carburized interior and exterior finish which is also applied to the barrel extension and gas port during heat treating and creates a monolithic black finish that is superior to hard chrome. The process does not add material to the internal dimension of the bore, increasing surface hardness to between 58-65 HRC, lowering bore friction, enhancing surface lubricity, improving running wear performance, enhancing corrosion resistance and heat resistance over industrial hard chrome.

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