20" Match Fluted H-Bar Barrel 1/7 Twist ($220)

20" Match fluted h-bar barrel is made from durable 4150 chrome moly vanadium, 5.56 NATO Chambering, 1 in 7 R.H. twist, 6-groove, stress-relieved, turned on center for precision accuracy and functioning, hardened to 26-33 Rc, corrosion resistant *Nitro Carburized finish. Particle tested, air guaged and threaded to accept standard 1/2"-28 tpi flash suppressors and muzzle brakes. The gas block diameter is .750. Beautiful top and bottom flutes aid in cooling and lighter weight. Includes ramped barrel extension w/M4 cuts, alignment pin, gas port hole drilled for a rifle length handguard and .750 gas block (not included; sold separately) area and head spaced. Made in the U.S.A.

*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.
