AbstractA firearm barrel nut assembly including barrel nut, generally cylindrical in shape with a threaded central bore, and an externally threaded locknut which is used in conjunction with the barrel nut to secure a barrel to a firearm upper receiver. The barrel nut has an integral bushing on its exterior constructed to support either the gas tube or piston of the host firearm's operating system. The barrel nut is configured so that it may be independently and non-rotationally held within a vice or other fixture during installation of the barrel and while the locknut is tightened to a preset torque to hold the barrel in place while the barrel nut is independent of the torque applied to the locknut to properly secure the barrel to the upper receiver.
