A practice weapon, having a conventional handle piece with a lock for a drop barrel, with a trigger mechanism which optionally has a rotary bearing for a rotatable trigger, with a spring base on which the return spring is supported; and with a practice breech with a fixed practice barrel. In order to permit a conversion without the use of a tool, an adapter is inserted into the handle piece, the adapter being supported firstly above the trigger mechanism, optionally above the rotary bearing, on a brace and secondly in the upper region of the spring base of the handle piece. Furthermore, the upper region of the adapter has guides for the practice barrel, and the lock interacts with a locking carriage, which is formed in a locking slot of the adapter, in such a manner that the locking carriage secures the practice barrel.

A method of modifying a firearm barrel comprising the steps of milling an existing barrel to create a sloped area with a larger diameter at a chamber end and a small action moving toward the muzzle end; placing an barrel nut on the barrel; placing a chamber bushing having a step with the step disposed at the chamber end; placing a brass pressing guide on the barrel and placing the barrel assemble with brass press guide and rear jacket tube in a press to press fit these components together; placing a gas block on the barrel adjacent to the rear jacket tube pressing the components tougher using the press; placing a front jacket tube on the barrel adjacent to the gas block and pressing the components tougher using the press; covering the threads of the barrel and placing a pour guide on the barrel; filling a void defined between the front jacket tube, rear jacket tube and barrel with a filler; placing a centering device on the barrel so that it is operatively associated with the front jacket tube to center the barrel in the front jacket tube while the filler is curing; placing a muzzle brake cap on the barrel and pressing the muzzle cap into the front jacket tube using the press; and, attacking a muzzle brake.

A training method and apparatus are disclosed. The training method may include converting a firearm capable of firing live ammunition to a pneumatic training device incapable of firing live ammunition. The training method may further include cycling a pneumatic training device through one or more cycles. Each of the cycles may simulate an actual firing of the firearm. Each of the cycles may also include triggering a trigger assembly of the pneumatic training device, using a charge of a pressurized gas to reset the trigger assembly, and advancing a counter of the pneumatic training device. After a certain number of cycles have been completed, a next cycle may be attempted, but not completed. Accordingly, the training method may enable a user to safely and realistically practice reloading, jam or malfunction clearing, or the like.

A barrel for a handgun includes an imaginary barrel bore axis along which it extends in the x-direction, around which barrel axis the following are formed in the interior of the barrel, in succession from a rear end to a front end: a cartridge chamber, which has a first diameter; a cartridge chamber opening, which has a second diameter; a conical transition, which transitions from the second diameter to a third diameter, which is associated with the guide region; and a barrel opening, an end face being formed around the cartridge chamber opening, and the barrel being suitable for a bullet driven by hot gases to accelerate therethrough. The end face is at least 1.5 times larger than the cross-sectional surface formed by the third diameter.

Methods of manufacturing metal, metal-matrix, metal-metal-matrix composite weapon barrels offer barrels with improved thermal performance and rigidity with no, minimal or negative weight increase. A barrel may include a barrel core surrounded by a lightweight, thermally conductive sleeve made from metal, metal-matrix composite (MMC) materials, also referred to as metal-matrix material. The barrel core and barrel sleeve may include aligning features to prevent separation and movement of the sleeve along the core. The disclosed methods provide for material combinations and part designs that prevent separation of their parts over the life of the weapon barrel and allow the barrel to perform at high cadence over the whole temperature range the barrel is used.

A noise suppressor for a firearm is provided that can be disassembled and is able to withstand full automatic fire. In various embodiments, a noise suppressor might include an outer tube, a distal end cap, and a pin(s). The outer tube might include a plurality of first holes spaced apart from each other along a circumference of a distal end of the outer tube. The distal end cap might include a plurality of second holes spaced apart from each other along a circumference of the distal end cap. One of the distal end cap or the distal end might be threaded into the other. Each of the pin(s) might be releasably inserted and affixed to at least one first hole and at least one second hole. A blank firing adapter is also provided that can be coupled to the noise suppressor (and can withstand live rounds being fired into it).

Improvements in a less-lethal force device are disclosed. The less-lethal projectile device generally comprising a projectile that is mated to a docking base by way of a spherical shaped projectile ball in a retaining spherical sockets or base. The projectile ball may include a locating/orienting that locates the projectile ball in the docking base. The retaining socket has one or more wings that partially wrap around the projectile ball. The material, thickness and splits in the socket adjust the retention force placed on the projectile ball. The projectile captures a fired bullet and is propelled along the original path of the bullet at a less lethal velocity. The disclosed system results in converting a normally lethal weapon into a less-lethal blunt impact system.
