Embodiments of the present disclosure relate to trigger mechanisms for firearms. In one aspect of the present disclosure, the trigger mechanism can include a linkage between a striker sear and a main sear to control an amount of force exerted on the main sear by the striker sear. A portion of the force exerted on the striker sear by the striker can be exerted on the main sear through the sear linkage. In another aspect of the present disclosure, trigger mechanisms are described which additionally, or alternatively utilize one or more biasing members to provide a variable trigger pull weight.

Trigger mechanism for a firearm

An adjustable insert for a firearm magazine can include: a contact surface to contact a cartridge shoulder; and an engagement interface positioned on a mating surface, the engagement interface being engageable with a portion of the firearm magazine, wherein the mating surface is positioned perpendicular to the contact surface; and wherein the engagement interface includes a predetermined adjustment resolution for incrementally adjusting the adjustable insert forward and backward along a plane parallel to a longitudinal axis of the firearm magazine to accommodate multiple sizes of cartridges.

A firearm can include a receiver, a bolt, and a gas block. In certain implementations, the receiver and/or barrel extension includes a locking shoulder, a lug-interface region forward of the locking shoulder, and a channel wall that defines a bolt channel and a bolt-lug raceway rearward of the locking shoulder. In some implementations, the bolt includes a bolt lug. The bolt lug can be sized and shaped to slidably engage the bolt-lug raceway. Additionally, the bolt can be positioned within the bolt channel of the receiver. Further, the gas block can be positioned at the lug-interface region. In some implementations, the gas block is rotatable with the bolt lug. In particular implementations, the gas block includes a raceway plug sized and shaped to block the bolt-lug raceway. The gas block can also include a bolt-lug notch sized and shaped to mate with the bolt lug.

Gas management for firearms

A number of embodiments of a firearm are disclosed where the firearm includes a magazine configured to hold the bolt in an open position when the magazine is empty. In one embodiment, the firearm includes a bolt stop mechanism that moves between a first position where it allows the bolt to cycle between an open position and a closed position and a second position where it holds the bolt in the open position. The magazine is configured to actuate the bolt stop mechanism to the first position when the magazine is empty.

Implementations of the present invention relate to devices, systems, and methods for the safe and efficient use of exercise equipment and, in particular, weight training equipment. A locking hub for weight training equipment may include a first hub and second hub, the first hub and second hub having a sleeve located therebetween. The first hub and/or second hub may hold one or more pads adjacent the sleeve. Rotation of the sleeve relative to the first hub and/or the second hub may compress the one or more pads to force the pads radially inward against a weight bar, substantially restricting movement of the locking hub relative to the weight bar.

A shotgun includes a forearm and a fastening mechanism that is used to couple the forearm to the remainder of the shotgun. The fastening mechanism moves between a first position where the forearm is coupled to the remainder of the shotgun and a second position where the forearm is uncoupled from the remainder of the shotgun. In one embodiment, the fastening mechanism is a lever-type fastening mechanism. In another embodiment, the fastening mechanism includes an anchor that is shaped to be received in a hole in a magazine of the shotgun. The anchor rotates between a first position where the anchor is unable to exit the hole so that the forearm is coupled to the magazine and a second position where the anchor is able to exit the hole so that the forearm is uncoupled from the magazine.

A magazine for introducing a plurality of ammunition cartridges into a firearm is disclosed. Particularly, a magazine may include a first rotor configured for rotating about a first center of rotation and a second rotor configured for rotating about a second center of rotation, wherein a position of the first rotor and a position of the second rotor are fixed with respect to one another. Further, operation of the first and second rotor may cause at least one ammunition cartridge of a plurality of ammunition cartridges that are movable by the first and second rotor to move along a serpentine path. Firearm systems including such a magazine are also disclosed. Another aspect of the present invention relates to a method of introducing an ammunition cartridge into a firearm. More specifically, an ammunition cartridge may be moved along a selected serpentine path prior to introducing the ammunition cartridge into a firearm.
