Abstract: A camblock assembly with a camblock and a guide rod is employed in a firearm having a frame constructed of synthetic polymer material. The camblock has a front flange with flange surfaces that engage corresponding bearing surfaces of the frame to distribute forces and energy to the frame during recoil of the firearm. A shelf member is positioned at a front end of the camblock and a coiled flat wire buffer spring is positioned about the guide rod to resist movement of a reciprocating slide. A detent mechanism positioned within the camblock contacts a surface of a slide stop pin to hold the slide stop latch in place. The interior of the slide stop latch contains an elongated wire having an end that engages the frame such that the slide stop latch is biased in a down position.

Abstract: A semi-automatic, two-shot, gas-operated shotgun having a side-loading port, lower barrel configuration with bottom shell ejection. Gas exit ports are spaced around the barrel and operate a piston which actuates a connecting rod assembly rearwardly. The rearward movement of the connecting rod assembly will comprise a recoil spring and cycle the next shell into the chamber from a shell space in the carrier above the breech. The bolt assembly has upper and lower bolt members. Locking lugs on the opposite sides of the lower bolt are released by rearward movement of the upper bolt member. Reciprocal guide pins are located in the lower bolt member and are retracted into the face of the lower bolt to allow a spent shell to be ejected through the ejection port. The impact of the lower bolt member at the rear of the receiver will drive the pins forwardly to direct a new shell into the breech.

Abstract: A short bolt rifle that enables increased barrel without an increase in weight. A longer barrel increases bullet velocity, which increases the range and accuracy of the weapon and the bullet impact energy. In this action, the bolt is simply pulled back and pushed forward. The design includes a loader mechanism that ejects spent cartridges and loads a new cartridge. This happens while the bolt is drawn back and pushed forward. A rotating lock secures the bolt in the firing position. A second version of the action uses a pistol grip. A lock holds the pistol grip, which can be released. After it is released, the user pulls down and back on the grip to open the action. The grip is pushed forward and upward, to load a shell, while the bolt is moved forward and locked. The action also can easily be adapted to fully automatic operation.

Abstract: A high power bolt action rifle combined with a removable “back up” single shot barrel. The bolt action barrel would preferably be on top of the single shot barrel. This arrangement facilitates with the ease of converting it from hunting dangerous game (incorporating both barrels) to hunting non-dangerous game (removing lower single shot barrel). When hunting dangerous game with this rifle one receives the full benefit of a bolt action, and that of a double rifle. After the bolt action is fired the hunter can decide whether to immediately follow up the shot by firing the single shot barrel or work the bolt and load the bolt action and fire the bolt action barrel again.

Abstract: A housing for use with a firearm is provided.

The second housing section has a forward portion which is offset from the first housing section and which includes a forward surface defining an opening sized for receiving a connecting element operatively connecting a lever disposed adjacent the top external surface outside the first housing section and the breechblock within the second housing section. The connecting element moves perpendicularly to the opening and not, as in prior art housings, along it, so that the previously required longitudinal slit, which severely weakened the structure of prior art housings, is avoided.

Abstract: The invention provides an apparatus for reducing recoil on a firearm or gun and to increase rate of firing. The invention uses a dual mass system to dynamically balance the gun wherein some of the energy of firing is absorbed within springs and thereby reduces the recoil force imparted to the gun user. The apparatus also comprises an ejector mechanism for ejecting a spent round and reloading a new round from the gun magazine with increased speed over conventional designs. The apparatus is applicable to automatic and semiautomatic handguns as well as rifles and machine guns.

Abstract: A bolt for a firearm has a front and rear portion with increased diameter front and rear bosses, thereby allowing for reduced clearance between the bolt and bolt runway. The front boss has major and minor diameter portions, with the major diameter portions being located directly behind the locking lugs, and the minor diameter portions being equal in diameter to the rest of the bolt body. The rear boss is located directly in front of the handle, and has a uniform diameter equal to the major diameter of the front boss.

Abstract: A muzzleloading rifle has a bolt with a laterally extending handle. The bolt is operationally connected to the cocking piece of the firearm by means of engaged cam surfaces of the bolt and the cocking piece which will permit the rifle to be cocked only by moving the bolt handle in an upwardly and rotational motion without any longitudinal movement of the bolt towards the cocking piece. After the firearm has been loaded by means of depositing a disc element with a primer element in the center bore thereof in the breech opening of the firearm, the firearm is placed in a firing condition by reversing rotational motion of the bolt handle. The disc element has a center bore which is adapted to receive a conventional nipple and a percussion cap, or in lieu thereof, and preferably, a shot gun primer. The latter is preferred in that it provides a hotter and more intense ignition of the gun powder in the muzzleloading rifle art.

Abstract: An improved bolt carrier for a firearm is provided that improves the overall reliability and performance of the firearm bolt assembly. The bolt carrier includes a bolt with a body having a number of lugs extending therefrom. The lugs are integrally connected to the body and define a fillet extending between a sidewall of the lug and the outer surface of the body of the bolt. The bolt also includes an extractor pivotably engaged in a recess formed in the bolt. The extractor has a pair of flanges configured to engage a pair of springs disposed on either side of a firing pin bore extending through the bolt.

Abstract: A repeating rifle having a bolt action comprises a breech housing (1), a breech body (3) which can be moved and can be rotated in this breech housing (1) and has a movable plug (4) and a firing pin (6) which is loaded by a firing pin spring (7) and has a cocking piece (8), in which case the breech body (3) has in its interior a cocking guide which interacts with the cocking piece (8). In order to achieve maximum safety and maximum operating convenience with as little physical complexity as possible, a cocking cam bush (33) is guided such that it can be moved in the longitudinal direction in the breech body (3) as the cocking guide, on which cocking cam bush the firing pin spring (7) is supported, and the plug (4) has a guide sleeve (36) which interacts with the cocking cam bush (33).

Abstract: A sleeve made of spring plate is positioned between the mushroom head and the breechblock carrier of a locked firearm. The sleeve is supported in the expanded state between the mushroom head and the breechblock carrier and, thus, prevents their being pushed together. During closure of the breechblock, the sleeve enters a fixed cone which compresses it radially in elastic fashion so that the sleeve can be inserted into an annular space in the mushroom head and/or the breechblock carrier. The radial compression of the sleeve permits the mushroom head and the breechblock carrier to be pushed together and, thus, permits relative rotation between the mushroom head and the breechblock carrier.
