Barrel Description: 300 AAC Blackout Barrel * 1x8 Right-Hand Twist, 6 groove * Button Rifled * Manganese Phosphated * Threaded Muzzle * 4150 CMV (chrome-moly vanadium) Steel. The precision 4150 CMV barrel with M4 cut extension, pulled-button rifling process, lapped bore, polished chamber. This barrel delivers pinpoint accuracy. Each barrel is concentrically cut and muzzle threaded 5/8 x 24 R.H. 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. Exterior includes detailed contouring, rich dark black manganese phosphate finish (parkerized). This fluted model features DEZ unique fluting designs to improve rigidity and aid in barrel cooling. This SBR uses a pistol length gas tube and hand guard.

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.
