I have a unfired proof research 16 inch AR barrel available. It's a 1-8 twist. 223 wylde. Mid length gas. It is pin drilled for a geissele super gas block .750. Barrel was installed but is unfired.I decided to go with a longer setup. The stainless areas have also been cerakoted black. 600.00 shipped firm. Chance to save a ton here on a precision or lightweight build.
