An adjustable firearm stock has a frame having a forward extending barrel defining a barrel axis and defining an elongated passage adapted to receive a reciprocating bolt, the frame having a first attachment facility registered with the barrel axis and adapted to receive a buffer tube defining a cavity adapted to receive a buffer spring operable to interact with the bolt, the frame having second attachment facility spaced apart from the barrel axis and from the first attachment facility, a telescoping stock defining a sleeve bore coaxial with the barrel axis and closely and slidably receiving the buffer tube, the stock defining a second bore parallel to and laterally offset from the first bore, an elongated support element slidably received in the second bore, and the support element having a forward end operable to removably engage the second attachment facility.
Firearms where the bolt catch can be released from either side using the same or a substantially similar motion using contact features that look, feel, or operate similarly on both sides, that are located within the firearm rather than externally, that can be used more easily or reliably, or a combination thereof. In some embodiments, a bolt catch engagement feature, magazine release mechanism, or both, are also (e.g., similarly) ambidextrous. In many embodiments, a user action on one side of the firearm is substantially similar to, but in the opposite direction from, a user action on the other side that performs the same function. In various embodiments, a left button, pad, or feature is directly opposite and in line with a right button, pad, or feature. Bolt catches can use two levers and magazine release mechanisms can use two parallel elongated members perpendicular to the barrel and a catch actuator.
F41A 3/42 - Semi-rigid bolt locks, i.e. having locking elements movably mounted on the bolt or on the barrrel or breech housing having rocking locking elements, e.g. pivoting levers or vanes hand-operated
F41A 3/72 - Operating handles or levers; Mounting thereof in breech-blocks or bolts
F41A 35/06 - Adaptation of guns to both right and left hand use
Firearms with improved systems and methods of controlling which side of the firearm shell casings are ejected from, with ejection port covers on both sides of the firearm that open to provide cross ventilation, or both. In some embodiments, the bolt can be installed in one of two different orientations to select whether shell casings are ejected from the left or the right ejection port without a need to replace any parts. In a number of embodiments, spring loaded ejection port covers on both sides open when the firearm is fired or when the bolt or carrier of the firearm moves to provide cross ventilation through a passageway through the firearm to cool the firearm. The covers can be manually closed by the operator when the weapon is not being fired to keep dirt and debris out of the firearm.
F41A 35/02 - Dust- or weather-protection caps or covers
F41A 15/14 - Cartridge extractors, i.e. devices for pulling cartridges or cartridge cases at least partially out of the cartridge chamber; Cartridge ejectors, i.e. devices for throwing the extracted cartridges or cartridge cases free of the gun for bolt-action guns the ejector being mounted on, or within, the bolt
F41A 3/12 - Bolt action, i.e. the main breech opening movement being parallel to the barrel axis
F41A 3/26 - Rigid bolt locks, i.e. having locking elements rigidly mounted on the bolt or bolt handle and on the barrel or breech-housing respectively the locking elements effecting a rotary movement about the barrel axis, e.g. rotating cylinder bolt locks semi-automatically or automatically operated, e.g. having a slidable bolt-carrier and a rotatable bolt
F41A 35/06 - Adaptation of guns to both right and left hand use

Firearms that pull back the carrier using a charging handle and carriers and charging handles for firearms. In various embodiments, the charging handle engages the carrier at a gas key or tab thereon. In some embodiments, the charging handle has a bridge or engagement face located between a rearward end and a forward end of the charging handle. In particular embodiments, the bridge extends from a left wall to a right wall of the charging handle. In some embodiments, the bridge, the left wall, the right wall, and a top wall are all one piece and a stem of the charging handle has an open bottom between the left and right walls. In various embodiments, the bridge does not extend below the left or right wall, the tab on the gas key extends upward between the left and right walls to engage the bridge on the charging handle, or both.
F41F 5/00 - Launching-apparatus for gravity-propelled missiles or projectiles
F41A 3/72 - Operating handles or levers; Mounting thereof in breech-blocks or bolts
F41A 5/24 - Mechanisms or systems operated by propellant charge energy for automatically opening the lock gas-operated by direct action of gas pressure on bolt or locking elements

Ambidextrous bolt catch and magazine release and firearm
Firearms where the bolt catch, magazine, or both, can be released from either side using the same or a substantially similar motion using contact features that look, feel, or operate similarly on both sides, that are located within the firearm rather than externally, that can be used more easily or reliably, or a combination thereof. In some embodiments, a bolt catch engagement feature is similarly ambidextrous. In many embodiments, a user action on one side of the firearm is substantially similar to, but in the opposite direction from, a user action on the other side that performs the same function. In various embodiments, a left button, pad, or feature is directly opposite and in line with a right button, pad, or feature. Bolt catches can use two levers and magazine release mechanisms can use two parallel elongated members that are perpendicular to the barrel with a catch actuator located between.
Firearms and handguards for firearms having three pivotably attached pods wherein a first pod is deployable as a monopod and second and third pods are deployable together as a bipod, or having at least one pivotable pod having at least one hinge pin, at least one locking pin, and at least one return spring that biases the at least one locking pin. In some embodiments, a return spring, a slide spindle, a locking spindle, or a combination thereof, push two locking pins, for example, into opposite detents when the pod is pivoted into a deployed position, and the pod can be released by moving a slide button and secured in a stowed position with a catch. In certain embodiments, the monopod is pivotably attached to the handguard aft of where the bipod is pivotably attached to the handguard. In particular embodiments, the firearm is an AR-15 or an M-16.
