    摘要: A barrel nut assembly for use on a variety of firearms is provided. The assembly is made up of a 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. The barrel nut assembly affords the user a method and apparatus that aligns a central bore in the bushing with the opening in the upper receiver that receives an operating system component of the firearm while the barrel nut is independent of the torque applied to the locknut to properly secure the barrel to the upper receiver.

    摘要: An externally threaded fastener is captivated by a component that includes an opening. The externally threaded fastener includes a thread and a non-threaded shaft. The opening includes a major diameter and a minor diameter. The minor diameter includes a first diameter portion, a second diameter portion, and orthogonal portions that connect the first diameter portion and the second diameter portion. To captivate the externally threaded fastener with the component, the externally threaded fastener is positioned within the component opening and the externally threaded fastener is angled relative to an axis of symmetry of the opening in order to engage the threads of the externally threaded fastener with the component opening until the non-threaded shaft is fixed against at least two planes of the component by the first diameter portion of the minor diameter.
