An upper receiver assembly for a firearm having an upper receiver with an integral barrel nut, a handguard assembly and a barrel nut assembly with a barrel and lock nut is provided. The barrel is received by the upper receiver and is secured directly to the upper receiver using the lock nut. The upper receiver also includes an integral handguard mounting member to which the handguard assembly may be directly attached. The upper receiver assembly allows the user to attach both the barrel and handguard assemblies directly to the upper receiver, independently of one another.

The present invention is directed to an adaptor for a suppressor comprising a gate for locking the suppressor on the muzzle and a threaded receiver for securing the suppressor to the firearm such that excessive play of the suppressor is removed. It is further directed to a method of securing a suppressor on a firearm by engaging a gate on an adaptor in a groove on a barrel of the firearm to lock on the adaptor, and any attached suppressor, and then tightening the suppressor and the adaptor on the barrel by threading the suppressor into the adaptor until excessive play is removed.

Presently disclosed is a locking device for a firearm that includes a longitudinally extending frame and a configurable butt support, a configurable action housing, and a barrel lock. The configurable butt support defines an opening for receiving a butt of the firearm, with one or more of the width, length or base of the opening being configurable. The configurable action housing defines a channel between interchangeable opposing profiles, which are associated with the configuration of one or more firearms and inhibit access to at least a trigger of the firearm. The barrel lock is configured to secure the barrel of the firearm when in a locked position, and to release the barrel of the firearm when in an unlocked position. The locking device may also include a biometrically activated lock, such as a fingerprint reader, and a communication interface to provide information about attempts to access the firearm.

Firearms have an alignment element configured to connect to the barrel with the threaded muzzle portion exposed forward of the alignment element, the alignment element having a lock element movable between a release position and an engaged position, a muzzle device having internal threads configured to mate with the threaded portion of the barrel, the muzzle device defining a lock channel adapted to receive the lock element in the engaged position, the lock channel including wall portions configured to contact the lock element in the engaged position to prevent rotation of the muzzle device, and the lock element in the release position being clear of the lock channel to enable the muzzle device to rotate for removal from the threaded muzzle portion. The alignment element may define a first bore portion configured to closely receive a selected barrel portion immediately aft of the shoulder surface.

A surface-mounted wall and/or vehicle locking and securing device for a firearm comprises a mounting bracket having a hinged lock bar connected at the second end of the mounting bracket. A magazine block is connected to the mounting bracket carrying a spring-loaded lock pin, which is dimensioned to pass through a hole or cut-out provided in the magazine block and the second end of the mounting bracket. A magazine mount tab is permanently attached to the mounting bracket for holding the magazine block. The device prevents the firearm from being loaded with ammunition and locks the firearm to a mounted surface using an external lock. The spring-loaded lock pin goes through the mounting bracket, magazine block inside the firearm and goes through a hole on the lock bar that comes through the firearm ejection port. The device has an automatic unlocking feature via a lock pin spring when the external padlock is removed from the pin lock tab and the lock pin. This allows the lock bar to automatically open for quick and easy removal of the firearm. Different external locks can be used to lock the firearm.

A device for assisting loading rounds into a firearm magazine (70) includes a body (12) that locks to the magazine using a catch pin 16. The body has a top opening (32) for a round (74). A press (40) hinged to the body top includes two plungers (44, 46) projecting down and aligned to enter the opening. A bullet pusher (60) is hinged to the body front and has a tongue (68) with a pushing surface (64). A wire (54) couples the press and pusher so that when the press is moved down, the pusher is moved out, and vice versa. A round is placed in the opening and on the tongue and the press is moved down to withdraw the tongue and push the round partly into the magazine. The pusher is then moved to the body to raise the press and push the round fully into the magazine.

A firearm apparatus is described comprising a firearm upper assembly and a firearm lower assembly, the firearm lower assembly comprising a firearm magazine container, wherein swapping of or refilling of a firearm magazine that is resident within the magazine container necessitates at least partial removal of the firearm upper assembly or may require complete removal of the firearm upper assembly from the firearm lower assembly. Further, such an apparatus requires removal of a firearm magazine retaining device that secures a firearm magazine lock wherein the retaining device is inaccessible without the at least partial removal of the firearm upper assembly from the firearm lower assembly. The firearm lower assembly may have a firearm magazine container that has a closed or partially closed bottom end to prevent switching out of a firearm magazine and the firearm lower assembly may have an opening in the top end sized for receiving a firearm magazine. A new firearm lower assembly is described that has no magazine position button as well as a conversion kit and a method of using a conversion kit to convert a semi-automatic firearm with a readily detachable firearm magazine into a firearm having a non-readily detachable firearm magazine.

A stock assembly and related method are provided. The stock assembly can include a base that can be joined with a weapon and a butt portion that movably extends from the base so the stock assembly can be adjusted in length. The stock can include an adjustment limiter configured to stop extension of the butt portion at a predetermined length, which can be set by a user to fit their stature. The butt portion can include a longitudinal axis and a limiter surface offset at an angle relative to the axis. The adjustment limiter can be a wedge that wedges against the limiter surface to set the stock assembly at the predetermined length, thereby automatically setting that length in a consistent and repeatable manner. A lock, separate from the adjustment limiter, can selectively lock the butt portion in a fixed position as or after the stock assembly attains the predetermined length.

An accessory mount for removably attaching an accessory to a firearm rail includes a base having a mounting rail, a lock block moveable in a recess of the base and a throw lever, which when activated, allows springs to move the lock block in the recess so the lock block disengages the firearm rail in an open mode. The thumb lever also can engage the lock block to a closed mode in which it clamps the mount to the firearm rail in a fixed position relative to the firearm. An accessory thus can be firmly, consistently and securely mounted relative to the firearm with the mount. The thumb lever can be joined with a threaded shaft that engages a threaded element, for example, a keps nut, associated with the lock block. A toggle lock can selectively engage notches in the threaded element to set the overall clamping force of the lock block and mount on the firearm rail.

The present invention is an ammunition magazine utilizing slide lock release relief depressions made to fit around a firearm slide lock release lever. The magazine body can further comprise trigger bar relief and frame relief depressions configured to fit around the corresponding components of a firearm, permitting the function of firearm components while maximizing the thickness of the firearm magazine body material.
