The muzzle-loading firearm has a barrel with a protrusion on the breech end of the barrel that fits into a matched groove within the mono block for use in aligning the barrel during assembly of the firearm. The muzzle-loading firearm has a barrel retaining nut, wherein the barrel retaining nut is internally threaded to accept the threaded end of the barrel thereby retaining the barrel in the mono block.

Abstract: The light-weight handheld less-lethal ballistic projectile launcher is configured as an “over/under” double barrel handheld device with a “break open” loading action. The launcher includes a barrel section pivotally connected to receiver section. The barrel section pivots between an open load/unload position and a closed firing position. The barrel section includes two metal barrel sleeves that are press fit into axial bores formed in the body of the barrel section. The barrel section also includes an ejector, which locks the barrel section in the closed firing position and partially expels spent rounds from the barrel sleeves when the barrel section is opened. The receiver section houses the launcher's fire control mechanism. The fire control mechanism uses a traditional single action operation and ensures that rounds are alternatively discharged from each barrel and prevents rounds from both barrels from being discharged simultaneously.

Abstract: A semi-automatic firing carbine anti-jamming cartridge loading system is provided wherein no feed lips or a portion of said feed lips are removed, wherein the cartridge to be loaded is fed to the carbine breech along a feed ramp. A bolt enclosing the firing pin includes a pivot plate mounted on the bolt nose, rotating about an axle. A recess formed in the bolt nose provides spacing for the pivot plate to rotate about said axle. If the firing pin protrudes through an aperture formed in the pivot plate, while the pivot plate is still in its collapsed state, then the weapon will jam by the firing pin hanging on the top part of a rim portion of the next loading round, thereby thwarting attempts at reconfiguring the weapon, that employs my novel system, to be re-converted as a fully-automatic weapon.

Abstract: An ejector mounting arrangement in a pistol frame cavity readily disassembled in which a pivot pin unit includes spring loaded detents engageable in holes in the cavity walls. The holes communicate with the exterior of the pistol so the detents can be pushed into the cavity to allow the ejector and pin unit to drop out. The ejector may also hold the hammer pin in place.

Abstract: The reliability of a cartridge ejection device can be improved by the interposition of a readily deactivatable control flap, arranged on the outside of a monobloc unit, between a control bolt and a cartridge ejector of a break-open gun-housing of at least one barrel. The arrangement has the advantage wherein when no shot has been fired, the ejector will move into the extended position gradually during tilting of the barrel. When a shot has been fired, the ejector will remained tensioned until the barrel has been entirely tilted. Another advantageous feature is obtained by constructing the cartridge ejector of two parts coupled by way of a spring, namely a cartridge extractor and an extractor element, because thereby stress peaks can be further reduced and the cartridge extractor can already be entirely in the retracted position even before the barrel is completely closed.

Abstract: A hand-held, single-shot grenade launcher including a receiver and attached stocks for both hands, a barrel slidable in the receiver, an assembly of Belleville springs for absorbing recoil and a breech connected to the end of the barrel. A grenade round is manually inserted in a firing chamber defined by the breech and the inner end of the barrel and cammed into firing position by a sliding breech block that carries a pivotal firing lever operated by a striker mounted in the receiver. The striker is biased by a helical striker spring and is cocked by a cocking lever associated with the right hand grip. The weapon is fired by depressing the cocking lever and thus pulling the trigger to cam the striker upward and release it from a sear operated by the cocking lever. Upon release the striker impacts an arm of the firing lever to drive a firing pin carried by the other arm of the firing lever into the primer of the grenade round casing.

Abstract: A double barrel derringer has an extractor mechanism which includes a T-shaped extractor element supported in a T-shaped slot which opens laterally outwardly through one side of the barrel and through the breech end thereof and communicates with the cartridge chambers. The extractor engages rimless cartridges disposed with the cartridge chambers within annular extraction grooves formed in the cartridges. A locking strap pivotally supported on the barrel locks the barrel in a closed position. Pivotal movement of the strap to a releasing position allows the barrel to be tilted from its closed position to a loading/unloading position. Further pivotal movement of the locking strap operates the extractor to simultaneouslly partially extract both cartridges from the cartridge chambers. The extractor is arranged for general lateral movement relative to the barrel to release the partially extracted cartridges which may then be dumped or manually removed from the cartridge chambers.

Abstract: A firearm with a barrel tiltable about a breechblock includes an ejector for throwing out a cartridge or cartridge case. The ejector is prestressed by a spring so as to be movable in discharge direction and cooperates with a locking pin such that in a first stage the movement of the ejector during initial tilting of the barrel is braked and is brought to a standstill while upon further tilting of the barrel, the ejector is accelerated in a second stage to expel the cartridge.
