  • Patent number: 10845152
    Abstract: An interchangeable barrel assembly for a firearm including a novel barrel and tool assembly which are used with a receiver having an open aft end. The tool assembly is configured to be inserted into the receiver open aft end so as to engage the aft end of the barrel. Torque applied to the tool assembly thereby transfers torque to the barrel without transferring forces to the action. This enables the same action to be used with different barrels and the barrel may be removed without removing the receiver or other components of the modular chassis or accessories mounted thereon. Additionally, standard torque may be applied to the barrel for connection to the receiver and firearm precision is maintained.

  • Patent number: 10808748
    Abstract: 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.

  • Patent number: 9506712
    Abstract: A firearm with tubular handguard mounting system is provided. The firearm includes receiver, a barrel having a breech threadably engaging the receiver, and a handguard. A primary barrel nut threadably engages the breech end of the barrel and is moveable into abutting contact with the receiver to form a tightened barrel to receiver connection. A secondary barrel nut threadably engages the primary barrel nut and is tightened thereto to trap an external annular barrel flange between the primary barrel nut and an annular abutment surface on the secondary barrel nut. The secondary barrel nut provides a free float tubular handguard, such as an AR-15 type handguard. Additionally, the primary barrel nut and secondary barrel nut provide a dual locking feature which resists loosening of the barrel connection.
