摘要： A firearm includes a receiver, a forearm pivotally attached to a distal end of the receiver, and a barrel having a barrel extension. A proximal end of the barrel and the barrel extension are secured within the forearm such that the barrel and barrel extension are laterally pivotable with the forearm relative to the receiver between a first assembled position and a second folded position. The forearm, barrel, and barrel extension may be secured to the receiver in the first assembled position for use of the firearm, after which the firearm may be folded for storage and/or transportation.

摘要： A method of modifying a firearm barrel comprising the steps of milling an existing barrel to create a sloped area with a larger diameter at a chamber end and a small action moving toward the muzzle end; placing an barrel nut on the barrel; placing a chamber bushing having a step with the step disposed at the chamber end; placing a brass pressing guide on the barrel and placing the barrel assemble with brass press guide and rear jacket tube in a press to press fit these components together; placing a gas block on the barrel adjacent to the rear jacket tube pressing the components tougher using the press; placing a front jacket tube on the barrel adjacent to the gas block and pressing the components tougher using the press; covering the threads of the barrel and placing a pour guide on the barrel; filling a void defined between the front jacket tube, rear jacket tube and barrel with a filler; placing a centering device on the barrel so that it is operatively associated with the front jacket tube to center the barrel in the front jacket tube while the filler is curing; placing a muzzle brake cap on the barrel and pressing the muzzle cap into the front jacket tube using the press; and, attacking a muzzle brake.

摘要： A barrel nut assembly for a firearm is disclosed. The barrel nut assembly may include a barrel nut comprising a plurality of expansion flanges. The barrel nut assembly also may include an expansion plug comprising an expansion surface. The expansion surface may be configured to abut and expand the plurality of expansion flanges when the expansion plug is attached to the barrel nut.

摘要： A suppressor assembly for a firearm including a barrel, a bore and a muzzle end. The suppressor assembly may include a gas block mount positioned about the barrel, and outer tube configured to be attached to the gas block mount, and a baffle configured to be attached to the muzzle end of the firearm. The baffle is telescopically received and configured to have a clearance fit with the outer tube. The baffle may also include one or more outer edges configured to scrape debris from the inner surface of the outer tube when the baffle is removed from the outer tube.

摘要： Quick take-down firearms and methods of using quick-take down firearms. The quick-take down includes an upper receiver coupling and a barrel coupling. The quick take-down can be unlocked by sliding a sliding lock collar in a translational motion to an unlocked position to release locking elements from a locked configuration. In the unlocked position, a barrel and handguard may be installed onto and removed from the upper receiver of the firearm. Releasing the sliding lock collar returns it to a locked position, securing the barrel and handguard to the upper receiver.

摘要： The invention comprises various minimal modifications to the upper receiver assembly of an AR-platform semiautomatic firearm whereby the firearm is reversibly converted to a pump-action firearm. The modifications comprise a means to introduce a push rod which passes through the front end of the upper receiver and connects a pump hand grip and the bolt carrier group of the firearm. The pump hand grip is guided and supported by the barrel and by a secondary guide rail disposed above the barrel.

摘要： This application is directed to a firearm that is functional, but is not fully functional as it is incapable of discharging ammunition, e.g., causing ammunition to ignite and discharge a bullet. Related methods, techniques, and approaches are also discussed. In embodiments, the firearm is functional, but not fully functional and it is impractical and/or irreversible to alter the firearm to make it fully functional through replacement of interchangeable parts that correspond to that particular firearm model. In embodiments, the firearm is also identifiable as being less than fully functional, e.g., it is incapable of discharging ammunition.

摘要： A method of making a continuous fiber barrel wrap sheath onto a steel riffled barrel liner of a gas-operated firearm is described. A wrap made up of composite fiber is wrapped onto a steel riffled barrel liner in a continuous fashion, with no interruption within the steel liner for the purpose of delivering high pressure gas through the steel liner. After joining the composite wrap to the steel barrel liner, either by mechanical or chemical procedure, a slot is formed by carving out a top and/or a bottom of the composite. A gas key insert is then placed in the made slots and retained by mechanical or chemical procedure. Finally, a gas port is drilled through the key insert.

摘要： A Universal Custom Recoil Solution will comprise of, a provided Firearm or barrel, prismatic shaped shell housing mounted or connected to the Gas Block Base, a Gas Block Base with pathways to direct firearms gas pressure from firing bullet into device interior pushing a Counter Weight, and Spring to counter act the firearms recoil when fired. This device is fitted to or around a provided barrel where the Counter Weight and spring are mounted on and reciprocate from front to back of the systems interior volume. The systems main function is to create a counter balance to the firearms kinetic energy by providing a moving mass, to counter the recoil from the firearms action movement when firing. The gas pressure is also expelled and redirected allowing the device to cycle synergistically with the firearm actions.
