    摘要： A firearm with safety mechanism in one embodiment comprises a receiver, a trigger-actuated firing mechanism with movable trigger operable to discharge the firearm, and a safety mechanism configured to arrest the firing mechanism. The safety mechanism is movable between a first position preventing movement of the trigger and a second position allowing movement of the trigger for discharging the firearm. In one embodiment, an elongated stock bolt attaches a buttstock to the receiver. The stock bolt passes through a portion of the safety mechanism to engage the receiver. This allows an operating button of the safety to be ergonomically mounted on a top surface of the firearm above the stock bolt. In one implementation, the firing and safety mechanisms may each be operably mounted in a fire control module disposed in the receiver and removable therefrom as a separate self-supported unit.

    摘要： A firearm with barrel extension comprises a receiver, a barrel supported by the receiver that defines an ammunition shell chamber, and a rotatable locking bolt having radial bolt lugs. The bolt is carried by a slide disposed in the receiver for forward and rearward movement. A barrel extension is mounted on a rear end of the barrel which includes radial bolt locking lugs that rotatably engage the bolt lugs when the bolt is in a closed locked breech position in battery with the head of a chambered shell. The barrel extension includes a rear facing annular rim seating surface formed integrally on the barrel extension as a unitary structural part thereof. The rim seating surface extends radially inwards from an interior surface of the barrel extension to engage and support the rear rim of the chambered shell. The headspacing is defined entirely by the barrel extension independently of the barrel.

    摘要： A shell feeding system for a top loading shotgun in one embodiment includes a barrel, receiver, and a magazine. The magazine includes a cavity configured to receive a plurality of ammunition shells in stacked end-to-end relationship. The magazine is positioned above the barrel and extends forward from the receiver. Shell guide grooves are formed by internal surfaces in the receiver which engage and guide each shell in a feed pathway towards the lower part of the receiver for chambering. A portion of the guide grooves may be arcuately shaped to rotate and reposition the shell for loading by the bolt into the chamber. In one embodiment, the receiver and magazine may be formed as a unitary integral structure formed as either a single piece or in half sections coupled together.

    摘要： A magazine assembly for a firearm in one embodiment includes an outer magazine housing configured for attachment to a firearm and a magazine removably insertable into the housing. The magazine includes an axially extending internal cavity configured to hold a plurality of ammunition shells in stacked end-to-end relationship. In one embodiment, the magazine has an elongated tubular body. A shell catch lever is slideably mounted on the magazine for linear and pivoting movement in one arrangement. The shell catch lever retains a shell in the magazine in a first lateral position and releases the shell from the magazine in a second lateral position. The shell catch lever operates to retain and release shells from the magazine when either removed from or positioned in the magazine housing for loading the firearm.
