A variety of apparatuses and associated methods are provided for providing a retractable suppressor system for gas generator systems such as a firearm. One embodiment includes a suppressor system that includes a retractable structure and housing, a fixed baffle, floating baffles, and springs to displace the floating baffles within the suppressor as the suppressor is extended from the housing along a gas generator system, e.g. a barrel of a firearm and thereby enclose the barrel within the suppressor. Embodiments of the invention permit full retraction, partial retraction/extension, or full extension of an exemplary suppressor with respect to an emission section of the gas generator e.g., firearm muzzle. Embodiments of the invention include an external latch which enables an operator to latch or unlatch the suppressor as it moves from one position to another and prevents accidental activation. Embodiments of the invention are configured to operate with accessory mounting systems.

A suppressor assembly attachable to a firearm is disclosed. The firearm may include a barrel and a muzzle end. The suppressor assembly may include a gas block positioned about the barrel, an outer tube attached to the gas block, and a baffle attached to the muzzle end. The baffle may push against the outer tube to compress the outer tube and apply tension to the barrel.

A muzzle adaptation system facilitates the attachment of adaptors to the muzzle of a firearm. A converter is attached to the muzzle of a firearm using existing features such as threads. The adaptors are secured to the converter by a release device that allows the adaptor to be attached without precise alignment or fasteners.

One aspect of the present disclosure is directed to a crush washer for a firearm that comprises a ring of material about a center axis having an inner surface towards the center axis and an outer surface away from the center axis, and at least one groove in the inner surface or outer surface. The groove forms: a first flange having an inner surface and an outer surface with a thickness therebetween; a second flange having an inner surface and an outer surface with a thickness therebetween; and a bridge connecting the first flange and the second flange, the bridge having an inner surface and an outer surface with a thickness therebetween. In an undeformed state, the inner surface of the first flange is adjacent to, but spaced apart from, the inner surface of the second flange. In a deformed state, the inner surface of the first flange is closer to the inner surface of the second flange compared to the undeformed state. The thickness of the bridge is less than the thickness of the first flange and less than the thickness of the second flange.

A silencer for a gun, in particular a handgun, is provided, comprising a silencer housing with a rear end wall which faces the barrel of the gun and with a front end wall which lies opposite the rear end wall. The silencer also comprises an attachment rail for attaching the silencer to the gun, with the attachment rail being arranged on the rear end wall of the silencer housing. The silencer can also be used as a duel simulator. Furthermore, a holster is also provided for holstering the firearm according to the invention.

A system for attaching an accessory to a firearm includes a muzzle device configured for attachment to the muzzle end of the firearm, the muzzle device having a first coarse-threaded engagement means and one of an annular grooved surface and a grooved surface engagement mechanism, and an adapter device. The adapter device includes an adapter having a forward portion including an accessory engagement means for receiving the accessory and a rearward portion having a second coarse-threaded engagement means formed on an inner surface of the adapter, a biasing mechanism received on the rearward portion, and a retainer ring received on the rearward portion adjacent to the biasing mechanism, the retainer ring having the other of the annular grooved surface and the grooved surface engagement mechanism. The male coarse-threaded engagement means and the female coarse-threaded engagement means cooperate to releasably secure the adapter device to the muzzle device.

A suppressor has a central expansion chamber and a coaxial expansion chamber. A front cap has at least one port in fluid communication with the coaxial chamber and an adjustable cover selectively movable between a closed position, in which the cover closes each port, and an open position, in which each port is open, thereby allowing selective control of the flow of gases and particulates exiting the coaxial chamber through each port.

An attachment system for attaching an accessory to the muzzle end of a firearm includes an accessory such as a silencer or sound suppressor, a muzzle adapter, and a multi-functional assembly, disassembly and locking device that locks the muzzle adapter onto the body of the suppressor. An end of the device is also configured to mate with the muzzle adapter to provide torque to selectively assemble or disassemble the muzzle adapter to the suppressor.

The disclosed magazine cap choke adapter allows a user to store an extra choke in place of the shotgun magazine cap. The magazine cap choke adapter is formed from a body that includes a first female threaded end, or proximal end, that threads onto the magazine adapter of the shotgun. Moving away from the proximal end, the magazine cap choke adapter tapers to a second female threaded end, or distal end, into which a choke is optionally threaded.

A firearm silencer includes a substantially cylindrical outer sheath having a first end and a second end, a barrel hole in the first end of the outer sheath, a damping element inside said outer sheath and connection means for connecting the silencer to a firearm barrel. The connection means include at least one clamping surface adapted to be pressed against the outer surface of said barrel. Further said connection means comprise a locking frame, at least one mounting lever hingedly connected to the locking frame and a twisting device functionally connected to the mounting lever for turning the mounting lever. At least one clamping surface is integrated to the mounting lever. Functional connection with the twisting device is arranged in a way that the mounting lever can by turned by using the twisting device.
