  • Patent number: 10281233
    Abstract: A system for reducing a recoil force transmitted upon firing of a firearm. The system includes a first stock portion having a first proximal end coupled to a receiver of the firearm and a first distal end having a distal contact surface, a second stock portion having a second proximal end with a proximal contact surface and a second distal end having a rear contact surface, and a resilient insert positioned between the distal contact surface and the proximal contact surface which is compressible by the relative motion between the first and second stock portions. The gun stock further includes a guide structure extending between the first stock portion and the second stock portion to control the relative motion between the first and second stock portions in response to the recoil force transmitted upon firing of the firearm.

  • Patent number: 10228202
    Abstract: A magazine for a firearm can have a housing defining a cavity with a biased follower arranged therein. The magazine may be configured to be received within a magazine well coupled to the receiver of the firearm so that rounds of ammunition stored in the magazine can be fed into the chamber of the firearm. In addition, multiple spacers can be received within the cavity defined by the magazine housing, which spacers may be configured to change or alter a width, dimension, size, and/or configuration of the magazine housing to allow the magazine to store and feed various and/or different caliber, length, size, and/or types of ammunition.

  • Patent number: 9816768
    Abstract: A firearm may have gas operating system that renders the firearm capable of firing a wide range of shot loads by passively or automatically compensating for different shot loads. The firearm may include a plurality of ports formed in the firearm barrel, and corresponding ports formed in a gas block of the gas operating system. The ports tap gases generated during firing which are used to cycle the firearm. When firing different cartridge loads, differing combinations of the ports are selectively at least partially blocked or otherwise obstructed by the cartridge casing according to the size of the cartridge. Additionally, the gas operating system includes compensating gas pistons with internal relief valves that can bleed off excess gas to compensate for larger shot loads regardless of the size of the cartridge.

  • Patent number: 9778002
    Abstract: A wad or shot cup having a forward cylinder portion receiving a payload and a rear cylinder portion receiving a charge of propellant. One or more latent deceleration features can be formed in a surface of the sidewall extending along the rear cylinder portion. The latent deceleration features can be spaced apart from a rearward end of the shot cup and can be deployed to form deceleration petals after the shot cup is fired from a firearm. A series of longitudinal slits can be formed in the forward cylinder portion so that a portion of the sidewall expands radially adjacent the longitudinal slits after the shot cup is fired from a firearm for urging at least a portion of the payload to exit the forward cylinder portion.

  • Patent number: 9658019
    Abstract: The disclosure generally relates to a booster for a silencer. The booster includes a piston with a proximal end and a distal end. The proximal end of the piston is configured to couple to a firearm such that a projectile can pass thorough the piston from the proximal end to the distal end. The distal end of the piston includes a flange with a plurality of spokes. The booster further includes a housing with an eccentric bore configured to couple to a silencer. The eccentric bore aligns the silencer below the sight plane of the firearm.

  • Patent number: 9562730
    Abstract: A feed ramp system for feeding cartridges into the chamber of a firearm. The feed ramp system includes a feed ramp insert having a body with at least one attachment tab projecting therefrom. The feed ramp insert is received within a mating recess formed in the receiver and is removably coupled to the receiver to enable replacement of the feed ramp insert. The feed ramp insert includes a pair of proximal ramp surfaces that align with distal ramp surfaces form at a breech end of the firearm barrel, to define a pair of feed ramps for directing cartridges into the chamber.
