A brace assembly includes a firearm attachment member to which a pivot arm is pivotally attached at a pivot. The pivot arm includes a brace member at an end opposite to the pivot. The firearm attachment member includes firearm mounting structure which includes a receiver support shelf for supporting thereon a receiver of a firearm, and a distal abutment against which a forward end of a receiver and/or a slide of the firearm is abuttable.

Firearms with combined bolt catch and ejector have a bolt defining a bolt face configured to receive a case head of a cartridge, a bolt catch connected to a frame and movable between a first operational position in which bolt reciprocation forward from the rear position is enabled, and a second restraining position in which a portion of the bolt catch restrains the bolt in the rear position, and the bolt catch having an ejector surface portion positioned clear of the bolt face when the bolt catch is in the first operational position and in registration with a portion of the bolt face when the bolt catch is in the second restraining position such that a case head received by the bolt face strikes the ejector surface portion upon movement of the bolt from the forward to the rearward position when the bolt catch is in the second restraining position.

The present folding stock adapter can be used with many types of military-type assault rifles that typically comprise a receiver extension, buffer and action spring. The present folding stock adapter can be used to add a folding capability to a standard stock allowing it to fold against a rifle's receiver when the weapon is not in use, thus reducing the overall length of the weapon. This reduction in length can facilitate its maneuverability, storage and transport in cramped quarters. The present device can also allow for the quick unfolding of the stock in order to allow the weapon to function and fire normally.

An adjustable stock system for a firearm can include a buttstock slider configured to be slidably attached to the firearm for moving relative to the firearm between a collapsed position and at least one extended position. The buttstock slider can include a plurality of buttstock grooves defined therein. The system can include a lower stock assembly that is configured to mount to a firearm and a latch assembly disposed within the lower stock assembly. The latch assembly is configured to be moveable between a latched position where the buttstock slider cannot slide relative to the firearm and an unlatched position where the buttstock slider is free to slide relative to the firearm. The latch assembly can include at least one latch tooth configured to mate with the plurality of buttstock slider grooves when the latch assembly is in the latched position. The latch assembly is biased to the latched position. The system includes an actuator assembly configured to move the latch assembly between the latched position and the unlatched position.

A handguard grip assembly has a connector to be fixed to a barrel of a rifle, the barrel having a barrel axis, a grip having a grip axis and adapted to be held by a user of the rifle and a flexible joint connected between the connector and the grip for allowing the grip and grip axis to pivot to any angle with respect to the barrel axis.

A stock mount assembly, which mounts a stock to a weapon, can include a base block including a longitudinal axis separating a first side and an opposing second side; a first lateral wedge opposing a second lateral wedge; a locking block slidably engaging the first lateral wedge and the second lateral wedge at a plurality of facets angled relative to one another; and a fastener aligned with the longitudinal axis. Rotation of the fastener can displace the locking block relative to the base block to urge the first lateral wedge and the second lateral wedge away from one another to forcibly engage first and second side surfaces of a cavity within the firearm to secure a stock to the firearm with the assembly. A related method of use is provided.
