The cable organizing member may include one or more elongated cable securing grooves, and the cable can be received in the cable securing groove by simply being pressed therein instead of dangling around. The organizing member may further include a cable receiving slot at a predetermined location on each of the cable securing grooves, and the cable can be slightly deformed and inserted into the cable receiving slot so the cable can be further secured on the cable organizing member.

Abstract: A device implementable on a firearm includes an adjustable multi-angle grip. The grip includes an upper portion and a lower portion. The upper portion is configured to be coupled to a receiver portion of the firearm. The lower portion is pivotably coupled to the upper portion via a hinge on a front side of the grip such that an angle between a longitudinal axis of the lower portion and a longitudinal axis of a barrel of the firearm is variable.

Abstract: A device is movably attachable to an upper receiver of a firearm adjacent to a rear end of an ejection port on the upper receiver. The device is configured to move linearly in directions parallel to a longitudinal axis of the upper receiver to function as a forward assist to cause a bolt carrier of the firearm to move forward with respect to the upper receiver. The device comprises a shell deflector having a deflection surface configured to deflect spent casings ejected out of the ejection port when the firearm is in operation.

Abstract: A device implementable on a firearm includes a forward assist assembly which is configured to be installed on an upper receiver of the firearm. When pressed, the forward assist assembly moves along a longitudinal axis thereof to engage with a serration cut on a bolt carrier of the firearm to push the bolt carrier forward with respect to the upper receiver when pressed. The forward assist assembly includes a modular component slidingly attachable to and detachable from the forward assist assembly.

Abstract: In one aspect, a gun sight may include a main body and a light tube. In one embodiment, the main body may include an elongated light tunnel housing and a base, wherein the light tunnel housing is formed on top of the base, and a light tunnel is formed inside the light tunnel housing. The light tunnel has a front end and a rear end, and the light tube is disposed at the rear end. In one embodiment, the light tube can be a fluorescent optical fiber that can be used as a light source for the shooter's eye even when the environment is relatively dark. In other embodiments, the light tube can be an integration of optical fiber and tritium. The light tunnel is tapered from the front end to the rear end to enhances the effect of light concentration in the light tunnel.

Abstract: In one aspect, a firearm grip may include an elongated grip body that includes a front side, a rear side, and opposing sides. The grip body may further include a front notch, side notches and a rear notch. A flange is formed on each side of the grip body between the rear notch and side notches. The front notch may include a first front securing edge and a second front securing edge. Likewise, the rear notch may include a first rear securing edge and a second rear securing edge. In one embodiment, the first front securing edge of the front notch and the first rear securing edge of the rear notch are configured to lean against the uneven surface, such as the edge of the desk to stabilize the firearm.

Abstract: Present invention discloses a rifle charging handle where one or two polymer pieces are made to fit over a T distal end of a main rigid body. A small protrusion on a hook shape latch, with limited elasticity, provides the locking mechanism to the upper receiver. The polymer pieces are secured by screws or other means; they provide a cost-effective option for ambidexterity variation and reduce metal wear on the upper receiver. The polymer pieces can also be secured to the main rigid body via a click-tab/click-hole mechanism. Other composite materials can be used to make the polymer pieces as long as they provide substantially similar rigidness and limited elasticity.

Abstract: A modular trigger control unit Is configured to be removably installed on a grip frame of a firearm and includes a locking block and a locking block pin. The trigger control unit has a protruding tab protruding rearward. The locking block includes slide rails extending forward, with each slide rail of the pair of slide rails having a flat wall extending downward with respect to the grip frame when the trigger control unit is installed on the grip frame. The trigger control unit is secured to the grip frame by: (1) the protruding tab received in a recess on an interior wall of a beavertail portion of the grip frame; and (2) the locking block pin traversing through a through hole on each flat wall such that removal of the trigger control unit from the grip frame requires removal of the locking block pin.

Abstract: Various examples of a modular trigger control unit for firearms are described. A trigger mechanism housing, as part of the modular trigger control unit, can be removably received in a grip frame of a semi-automatic firearm such that, when received in the grip frame, a serial number of the firearm displayed on the trigger mechanism housing faces a back side of the grip frame and is visible through an opening on the back side of the grip frame.

Abstract: Various examples of a modular trigger control unit for firearms are described. The trigger control unit can be removably installed on a grip frame and installed between the grip frame and a slide assembly of a semi-automatic firearm. The trigger control unit includes at least a trigger pin and a trigger pivotable around the trigger pin when pulled. In response to the trigger being pulled by a user when the trigger control unit is installed between the grip frame and the slide assembly, a firing pin lug of a striker-firing mechanism in the slide assembly is released thereby allowing a striker of the striker-firing mechanism to move forward with respect to the slide assembly. Moreover, the trigger control unit is secured to the grip frame at least by the trigger pin such that removal of the trigger control unit from the grip frame requires removal of the trigger pin.
