A chassis includes an internal portion which corresponds to a rifle action of a first type. The chassis further includes an external portion which corresponds with a rifle stock. The chassis is attached to the rifle action of the first type and to rifle stock.

Firearm associated electronic devices are provided. In one aspect a firearm associated device has a housing having a holding area and an opening through which a removable component may be positioned in the holding area, a door movable relative to the housing and having a door latch that moves along a path as the door moves and a housing latch movable between a first latch position where the housing latch is not in the path to a second latch position where the housing latch blocks movement of the door latch from a first range of positions where the door prevents the removable component from passing through the opening to a second range of positions where the door does not prevent the removable component from passing through the opening. A housing latch biasing member biases the housing latch into the second latch position. When the door latch is in the first range of positions and the housing latch is in the second latch position the door latch is movable along the path but is blocked by the housing latch from passing to the second range of positions.

Trigger module securing apparatus using internally threaded pins and threaded fasteners to secure a trigger module into the lower receiver of a rifle.

A apparatus implementable on a firearm includes a handguard assembly which is configured to at least partially surround a barrel of the firearm when the handguard is installed on the firearm. The handguard includes at least first and second physical features such that: (a) the first physical feature is configured to accommodate mounting of an accessory of the firearm on the handguard, and (b) the second physical feature is configured to secure a cable of the accessory onto the handguard.

A firearm includes a barrel having a breech end. An upper receiver is engaged with the breech end of the barrel such that a majority of the barrel is outside of the upper receiver. A lower receiver is releasably connected to the upper receiver, and the firearm includes structure for slidingly connecting the upper receiver to the lower receiver.

A fully automatic small arms demilitarization system includes individual infeed conveyance systems loaded at a single process initiation location; multiple hydraulic press stations fed by the individual infeed conveyance systems; and the multiple hydraulic press stations configured to crush one section of each weapon per cycle, incrementally crushing an entire length of each weapon, completely distorting each weapon to preclude restoration to a useable condition. The system further including an output system configured to output demilitarized weapons onto a common outfeed conveyance system that delivers the demilitarized weapons to a single recycle bin.

Takedown pins for rifles have a pin movable in a direction along its length between an operating condition and a released condition. The pin has a first end portion that prevents relative movement of the upper receiver with respect to the lower receiver when the pin is in the operating condition. The first end portion has a lower end portion surface adapted to resist upward movement of the upper receiver's lug. The pin has an intermediate portion adjacent to the lower end portion surface defining a lower channel having a lower channel surface above the level of the lower end portion surface. When the pin is in the released condition, the lower channel is registered with the lug, and the lug is enabled to move upward with respect to the lower receiver by a limited distance to a disengaged position.
