  • Patent number: 10309736
    Abstract: A shell loading system for a firearm in one embodiment includes a barrel, receiver, reciprocating slide and bolt assembly, tubular magazine, tilting carrier operable to receive and feed shells from the magazine into the action, a spring-biased carrier latch laterally moveable to engage the carrier, and a pawl pivotably mounted on the carrier. A carrier latch disconnect is movable between an unblocking and blocking position that prevents engagement of the carrier latch with carrier. To prevent bouncing of the carrier after firing a shot, a first detent feature on carrier assembly automatically engages a second detent feature in the receiver as the carrier returns downward from an upward position when the action is cycled by discharging the firearm. The detent features automatically disengage when the slide moves rearward to permit normal operation of the carrier when cycling the action.

  • Patent number: 8925230
    Abstract: A bolt handle assembly for a firearm is disclosed. In one embodiment, the bolt handle assembly includes a bolt having an internal channel and a laterally extending slot, a bolt handle including a mounting tang insertable through the slot and having a locking aperture positioned in the internal channel, a firing pin striker slidably disposed in the internal channel, and a locking member mounted on the firing pin striker. The locking member is insertable through the locking aperture of the bolt handle and is configured for engaging the mounting tang of the bolt to removably secure the bolt handle to the bolt. The locking member is rotatable between locked and unlocked positions to secure and release the bolt handle from the bolt. A method for mounting the bolt handle to the bolt is also disclosed. In one embodiment, the firearm is a bolt-action rifle.

  • Patent number: 8881444
    Abstract: A stock bedding system for a firearm is disclosed. In one embodiment, the stock bedding system includes a stock having a pair of bearing surfaces that are configured and arranged to mutually engage a mating pair of bearing surfaces formed on the barrel-receiver assembly. At least one of the four bearing surfaces has a predetermined convex surface profile which causes the barrel-receiver assembly to roll in an angular direction away from one lateral side of the stock towards the opposite lateral side when the barrel-receiver assembly is mounted to the stock. The convex surface profile acts to tighten the engagement between the opposing bearing surfaces of the barrel-receiver assembly and stock providing a secure and vibration resistant mounting. In one embodiment, the convex-shaped bearing surface is defined by a pillar lug mounted in the stock which engages a mating substantially flat bearing surface formed on the barrel-receiver assembly.
