Folding gun

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.

Knife handle

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.

Ammunition magazine with asymmetric feeding

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 switches arranged along a path of the magnets when the follower moves along a length of the magazine, the switches configured to activate based on a magnetic field exceeding a threshold, and a first antenna arranged on an inside of the magazine and parallel to a firing direction of the firearm, and configured to wirelessly transmit a round count indication to a second antenna on the firearm, the round count indication based on the round count data, the second antenna affixed to an inside of a magazine well of the firearm and mostly overlapping with the first antenna.

Determination of round count by hall switch encoding

A firearm magazine assembly and a related method are disclosed. The follower has a top platform, a proximal end, a distal end, and at least one slider rail on a first side of the follower. At least a portion of the at least one slider rail is at a position that is between and remote from both the proximal end of the follower and the distal end of the follower. The housing is shaped to receive the follower. The housing has a first wall having a first recess for receiving the at least one slider rail, the first recess defined by opposing surfaces. At least a portion of the at least one slider rail is shaped to engage the two opposing surfaces to limit tilt of the follower.

Compact anti-tilt follower for an ammunition magazine

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 &#x3c;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 &#x3c;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.
