Precision 4150 CMV barrel with M4 cut extension, chrome lined, 9 mm, pulled-button rifling process, lapped bore, polished chamber and 11º crowned barrel delivers pinpoint accuracy. Each barrel is concentrically cut and muzzle threaded ½ -36 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), and oil.
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.
