DEZ Arms' custom machined match barrels are made from 416R stainless steel manufactured in the USA. Barrels are head spaced with Alexander Arms' 6.5 bolt, have M4 feed ramped extension installed, pre drilled gas port hole with Nitro Carburized 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, 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. Fluted models feature DEZ unique fluting designs to improve rigidity and aid in barrel cooling.

*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.

The match barrel is machined to rigid specifications
