Magazine release apparatus and firearms including such magazine release apparatus are disclosed. An example bolt release for use with a firearm includes a first handle to protrude from a first side of the firearm and a second handle to protrude from a second side of the firearm. The first and second handles are integral. The first and second handles are to enable the bolt release to be operable from the first and second sides of the firearm. The bolt release includes a pivot axis adjacent the first side or the second side. The pivot axis is to enable the bolt release to be pivoted between a release position and a retained position. The bolt release to be biased toward the release position.

Bolt releases and firearms including such bolt releases

Magazine release apparatus and firearms including such magazine release apparatus are disclosed. An example magazine release apparatus for use with a firearm includes a magazine retaining arm including a longitudinal slot, a first handle to protrude from a first side of the firearm and a second handle to protrude from a second side of the firearm. The second handle includes a rocker arm having a feature to be supported on a receiver of the firearm. The first and second handles are actuatable to move the magazine release apparatus between a magazine retaining position and a magazine releasing position. In the magazine retaining position, the second handle is at least partially supported by the longitudinal slot and the feature extends toward the receiver.

A firearm includes a cocking lever, a shoulder-stock receptacle and a shoulder support having a shoulder stock configured to be joined by a connector to the shoulder-stock receptacle. A shoulder-stock adjuster is configured to adjust a position of the shoulder stock relative to the shoulder-stock receptacle along an adjustment axis. A cheek rest is mounted via a bearing on the shoulder stock so as to be movable in a direction parallel to the adjustment axis. A stop is disposed on the shoulder-stock receptacle so as to limit a movement path of the cheek rest towards a front of the firearm. At a position of the cheek rest defined by the stop of the shoulder-stock receptacle, the cocking lever does not collide with the cheek rest, even in a completely retracted state.

Coupling pins for connecting weapon components are described. An example fastener to couple weapon components includes an elongated body defining a first aperture. The first aperture being defined along a longitudinal axis of the elongated body. Tension member and a biasing element being positioned within the first aperture. The elongated body defining a second aperture. The second aperture being defined through a portion of the elongated body to enable a tension element, positioned at least partially within the second aperture, to be urged from the elongated by via an interaction with the tension member. The fastener is insertable into aligned apertures of respective first and second weapon components. The tension element being urged from the elongated body to interact with the second weapon component to urge the second weapon component into further engagement with the first weapon component.
