The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot. The first-pivoted charging handle may then be pulled rearwards to unfold the firearm. The first-pivoted charging handle may then be pulled further rearwards to rack the slide of the foldable firearm.

This disclosure describes systems, methods, and apparatus for a magazine assembly for a firearm, the magazine assembly comprising: an elongated housing, a spring positioned in an interior of the housing, a first and second plate at a proximal end of the housing, at least one follower configured to support one or more cartridges and move or slide within the housing based on a compression and decompression of the spring, one or more feed lips positioned at a distal end of the housing, the one or more feed lips adapted to prevent upward movement of a topmost of the one or more cartridges until a bolt or slide chambers the topmost of the one or more cartridges, and wherein the topmost cartridge is arranged off-center from the bolt of the firearm so as to increase an engagement or overlap between the bolt and the topmost cartridge.

A firearm stock includes a comb and a storage cavity that includes an opening extending through at least a portion of the comb. A storage lid is configured to at least partially cover the opening, wherein the storage lid has an open position and a closed position. In some embodiments, a cheek riser is attached to the storage lid. Other firearm stocks and firearm stock accessories are disclosed.

A translucent magazine for a firearm may be formed from a mixture of Polyetherimide (PEI) and at least one of the following: Polyphenylsulfone (PPSU), Polyethersulfone (PES) and Polysulfone (PSU). The translucent magazine including a follower, floor plate, and a follower spring. The follower being opaque. The follower residing within a casing.

A device may include a housing defining a first groove and a second groove and a clamp system comprising: a first clamp comprising a first protrusion and a second protrusion, and a second clamp comprising a first protrusion and a second protrusion. The first protrusion of the first clamp is configured to couple with the first groove of the housing and the first protrusion of the second clamp is configured to couple with the second groove of the housing, wherein the second protrusion of the first clamp is configured, to couple with the rearward facing rail and the second protrusion of the second damp is configured to couple with the rearward facing rail.

This disclosure describes systems, methods, and apparatus for detecting and displaying a number of rounds in a firearm magazine comprising a maximum number of N rounds. The magazine may comprise a follower, magnets on the follower, and <N magnetic-field-sensing sensors arranged along a path of the magnets when the follower moves along a length of the magazine, the sensors generating round count data based on a position of the one or more magnets relative to the <N magnetic-field-sensing sensors, and a first substantially flat antenna arranged on an inside of the magazine and configured to wirelessly transmit a round count indication to a second substantially flat antenna on the firearm, the round count indication based on the round count data, the second substantially flat antenna affixed to an inside of a magazine well of the firearm and mostly overlapping with the first substantially flat antenna.

A safety selector lever assembly may include a selector core comprising an elongated section having a curved and at least one angled face, a first and second extension positioned on opposing ends of the selector core, each comprising an extension aperture, and wherein the elongated section is positioned between the first and the second extensions, a plurality of levers, each comprising: a proximal and distal end, a recess for receiving one of the first and the second extension, a pin aperture, a pin, wherein at least a portion of the pin can pass through the first pin aperture and the extension aperture, and wherein rotation of the levers to a first position enables firing of the firearm and rotation to a second position precludes firing of the firearm.

Embodiments of the disclosure relate to adjustable stocks for firearms and methods for installing an independently sprung tensioning mechanism. The adjustable stock comprises a stock body attached to a buffer tube, with a lever-operated tensioning mechanism. The mechanism includes a tensioning block with fins to grip the buffer tube, an indexing pin, and a retaining pin. When the lever is depressed, the tensioning block and indexing pin disengage, allowing longitudinal adjustment of the stock on the buffer tube. The tensioning block applies upward pressure on the tube, compensating for rotational tolerances during assembly. Both the tensioning block and indexing pin move independently when engaging with the buffer tube but move together when disengaging. The indexing pin is biased towards the buffer tube by a spring, while another spring biases the tensioning block. The lever engages the retaining pin to retract both the indexing pin and tensioning block.

This disclosure describes a knife, the knife including a blade having a cutting edge and a tang, wherein the cutting edge comprises a serrated portion having a plurality of serrations, the plurality of serrations positioned between a proximal end of the blade and a distal tip of the blade, wherein the serrated portion further comprises a plurality of recessed portions, and wherein each of the plurality of serrations is positioned adjacent at least one recessed portion; and wherein each recessed portion includes a top edge, a bottom edge, and at least one tapered portion, wherein one or more of the at least one tapered portion of each recessed portion is positioned adjacent at least one of the plurality of serrations.
