A pistol brace for a pistol having a frame with a rear end portion and defining a median plane longitudinally through the pistol. The pistol brace has a longitudinal support configured to attach to and extend rearwardly from the pistol frame. A first plate and a second plate are pivotably attached at an upper end portion to the longitudinal support and extend down from the support in opposed alignment. The first plate and second plate can pivot independently of each other. Optionally, a flexible strap is connected to the first plate and second plate. The strap defines an adjustable passageway for the user's forearm.

A multi-caliber automatic rifle (AR) magazine is configured to alternately receive a first cartridge having a first caliber and a second cartridge having a first caliber. The multi-caliber AR magazine includes a first pair of ribs, a second pair of ribs, and a third pair of ribs such that the first pair of ribs and the second pair of ribs are configured to both support the body of the cartridge when loaded in the magazine. The second pair of ribs are indented toward a center of the multi-caliber AR magazine housing more than the first pair of ribs such that a distance between the second pair of ribs is less than a second distance between the first pair of ribs. The third pair of ribs can be rebated to form a dual-curved rib having a central convex portion connected between two concave portions.

A firearm trigger assembly is disclosed. The disclosed assembly may include a trigger, a disconnect, and a hammer, each of which may be configured to be spring loaded when installed in a firearm receiver. Installation of the trigger assembly in a firearm receiver may include pivotally coupling the trigger and disconnect to the firearm receiver using a trigger pivot pin, and pivotally coupling the hammer to the firearm receiver using a hammer pivot pin. The trigger may include an integral sear feature configured to provide a mechanical stop to the hammer. The disconnect may be configured to be at least partially located in a disconnect slot located alongside or adjacent to the trigger sear feature when the disconnect is pivotally coupled to the trigger. The disconnect and hammer may each include integral cam features configured to buffer hammer contact during firearm recoil.

An adjustable stock assembly includes a housing, a stock rail, a release, a key movable with respect to the release, a latch rotatable about a latch pivot between a latched position, an unlatched position and a disassembly position, and a latch cam pin coupled to the release. The housing is extendable and retractable with respect to the stock rail. The stock rail has a slot and one or more recesses adjacent to the slot that can engage the latch, thereby preventing disassembly of the rail from the housing and further securing the rail in a particular configuration. When partially depressed along with the key, the release disengages the latch from the stock rail recesses, allowing the housing to extend and retract within its adjustment range. The housing can be disassembled from the stock rail when the key and release are fully depressed.

Latch and release mechanism for adjustable firearm stock

A foldable firearm sight assembly including a leaf spring is disclosed. The disclosed assembly may include a base, a sight arm, and a leaf spring. The base of the sight assembly may be configured to attach to a firearm rail using, for example, a clamp bracket and a clamp bolt. The sight arm may be rotationally coupled to the base, and the leaf spring may be positioned between the base and the sight arm. When installed in the sight assembly, the leaf spring may be deflected and may apply a biasing force to the sight arm, causing the sight arm to favor either a deployed or stowed (undeployed) position. The sight arm may be lockable in stowed and/or deployed positions using a tooth and aperture configuration. In such lockable cases, the arm may be unlocked/released by manually depressing an end of leaf spring.

A non-detachable magazine configured to be used for new manufacture of firearms or configured to replace a detachable magazine of an existing firearm is disclosed. The magazine may be pivotally mounted on a firearm using a hinge pin, allowing the feed end of the magazine to enter and retreat from the magazine well of the firearm. The magazine includes a magazine body and at least one arm connecting the magazine body to the hinge pin. In some embodiments, a firearm can be made compatible with the disclosed non-detachable magazine such that removal of the magazine is tantamount to disassembly of the firearm, and/or removal of the magazine renders the firearm inoperable.

Non-detachable magazine

A locking adjustable cheek rest comprising an upper U-shaped portion and a lower portion located on the stock of a rifle or other firearm. The U-shaped portion is biased against the lower portion, such that the walls of the U-shaped upper portion press against the lower portion, thereby locking the upper portion in position. A first release and a second release are depressed to release the bias and enable the upper portion to be raised and lowered relative to the lower portion. Interlocking mechanisms located on the upper and lower portions facilitate locking of the cheek rest in a position determined by the user.

Adjustable cheek rest

A rail mountable diopter rear sight has a housing, a drum arm pivotably connected to the housing, a sight drum rotatably engaged with the drum arm, and elevation adjustment screw connected to the drum arm and the sight drum. The sight drum rotates on a common axis with the elevation adjustment screw. The sight drum threadedly engages a threaded portion of the elevation adjustment screw.
