We started with a 11.5" 1/7 twist barrel for this build. The barrel is made from 4150 machine gun steel with QPQ nitride treatment to the exterior, bore, and chamber. The upper receiver is T marked and is type 3 hard coat black. This does have M4 ramps. The Flash hider is a A2 this is for PISTOL OR SBR USE ONLY. Our barrels are Mil-Spec or better. We recommend a 55gr or 62gr bullet for best accuracy. The front sight is a A2 F-Marked with bayonet lug and attached with taper pins.
