20" TWISTER - Fluted H-bar (med. wt.) Barrel ($220)

20" Match Fluted Twister Barrel. The precision 4150 chrome moly vanadium barrel with M4 cut extension, chambered 5.56 NATO, 1:7 RH twist, 6-groove, pulled-button rifling process, lapped bore and 11º target crowned barrel delivers pinpoint accuracy. Muzzle thread 1/2 x 28 and the diameter at the gas block .750. Each barrel is concentrically cut and target crowned, 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. Exterior includes detailed contouring, rich dark black *Nitro Carburized finish. Our 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. Barrel is sold stripped; set it up your way without paying for extras. Ready for YOUR choice of rifle hand guard, .750 dia gas blocks, and front sights (not included; sold separately).

*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.
