The firearm lock is an independent structure requiring no installation process.

US12292249 - Adjustable bipod

A firearm support includes a housing, two or more legs, a column, a firearm mount, and a remote actuator. The housing including a first hydraulic cylinder. The two or more legs are pivotally coupled to and extending from the housing. The column resides at least partially within the first hydraulic cylinder. The firearm mount supports a firearm and is attached to a distal end of the column opposite the first hydraulic cylinder. The remote actuator is fluidly coupled to the first hydraulic cylinder through a hydraulic hose. The remote actuator adjusts a height of the column by moving hydraulic fluid through the hydraulic hose in response to rotation of a height adjustment knob on the remote actuator.

US12292250 - Recoil buffer assembly

A recoil buffer assembly for cushioning the impact of recoiling components of a firearm. The recoil buffer assembly comprises a first spring, a second spring, and a buffer. The first spring extends along a first axis. The second spring extends along the first axis. The buffer is positioned between a first end of the second spring and a second end of the first spring. The first spring is configured to act between the buffer and a bolt within the firearm. The second spring is configured to act between an end of the firearm and the buffer. A receiver assembly and firearm comprising the recoil buffer assembly are also included.

US12292251 - Adjustable gas block for firearm

An adjustable gas block for a firearm comprises a housing adapted to be attached to a barrel of the firearm. The housing has a first passageway adapted to be aligned with a gas port in a barrel of the firearm and a second passageway adapted to receive a gas tube of the firearm, such that a bore of the barrel, the gas port of the barrel, the first passageway, and the gas tube are in fluid communication. A valve member is mounted in the housing for forward and rearward sliding movement and has a first portion and a second portion. The first portion has an upwardly facing surface having a radius of curvature that closely approximates a radius of curvature of an outer diameter of the gas tube, and the second portion has threads. A nut is carried by the housing for rotational movement and has threads mating with the threads on the second portion of the valve. Rotating the nut in a first direction translates the valve member forwardly and rotating the nut in a second opposite direction translates the valve member rearwardly. The axial position of the first portion of the valve member controls the amount of gas passing from the first passageway to the gas tube by completely opening, partially opening, or completely closing the first passageway.

US12292252 - Feeder door and method of use

A feeder door of a feeder of a machine gun, the feeder including a feeder housing and the feeder door spring-loaded and pivotally coupled via a pivotal coupling to the feeder housing between at least an open position and a closed position, the feeder door comprising a base including a slot; a retainer lever; and a pivotal coupling independent of the feeder door and feeder housing pivotal coupling configured to spring-load and pivotally couple the retainer lever to the feeder housing between at least a stowed position with the retainer lever retracted in the slot of the base of the feeder door and a deployed position with the deployable portion extending outwardly from the slot of the base feeder door.
