摘要： PROBLEM TO BE SOLVED: To provide gun barrel arms avoiding approximately a stroke effect of the gun barrel, dispensing with a guide slot in a cradle tube, and slidably journaled in the cradle tube capable of replacing the gun barrel.
SOLUTION: The gun barrel (2) is journaled to first and second slide bush bearings arranged on the ends on the muzzle side and the rear body side of the cradle tube (3). The first slide bush bearing is constituted without the stroke effect and has a tube bush (7), and the outside face (8) of the tube bush is journaled movably by sliding in the cradle tube. Each tube bush has inside four groove-shaped recessed parts (9) distributed and arranged uniformly in the circumferential direction. Four strip-shaped projections (10) are arranged on the gun barrel, and the projections are inserted into the groove-shaped recessed parts on the tube bush. Plays for absorbing extension of the gun barrel generated at the firing time are provided between the outside surface (11) coupled with the gun barrel in a complementary shape and the inside surface (12) of the tube bush, and between a strip head (13) and the inside surface (14) of the groove-shaped recessed parts.

摘要： A weapon system includes a receiver and an operating group with a barrel extension arranged to axially translate relative to the receiver. In the firing condition, the op-rod assembly and bolt assembly are driven by the drive spring such that the round is guided into the chamber and the op-rod assembly and bolt assembly are locked to the barrel extension and a forward momentum of the op-rod assembly is imparted to the operating group and the round is fired. A portion of an impulse stops the forward momentum of the operating group. In the recoil condition, the operating group is driven rearward by the remaining portion of the impulse, the gas accelerator imparts additional rearward momentum to the op-rod assembly and bolt assembly and stops rearward momentum of the barrel and barrel extension, and the op-rod assembly and the bolt assembly are stopped by the drive spring.

摘要： A semi-automatic and automatic firearm of the "bull pup" configuration with bosses on the receiver for direct mounting of the sighting device and fixing thereon by rotatable fasteners. The bolt carrier has guide tubes riding on guide rods fixed to the stock; and, the tubes and rods have longitudinal grooves to expel water. The firearm is gas operated with an adjustable gas block with raised dots and letters indicating the setting. The firearm has a two stage operation in which a first trigger position results in a single shot and a second trigger position results in multiple automatic shots when the selector is In automatic position. When the selection is in the burst position, the first trigger position gives a single shot and the second selector gives a predetermined number of shots in a burst. The magazine is provided with longitudinal and transverse reinforcing ribs with a recess in the ribs allowing the magazine to be inserted in the firearm. A forward assist button is provided forward of the front of the bolt. The bolt carrier is provided with rollers at its top; and, sliding contact surfaces are micro-finished and coated for wear and friction resistance.

摘要： A modular system for hunting guns comprises barrels (13) of various calibres capable of being attached to a stock which forms a basic unit by means of fixing rails (19) arranged on the barrel and a corresponding fixing tongue (11) arranged on the stock. The stock may constitute a repeater rifled gun of long or short construction or a single-barrel rifled gun, so that different combinations of calibres and types of gun can be composed as desired. The barrel has a locking bush at one end with locking buttons which co-operate with an interchangeable locking head (47) provided with corresponding locking buttons. A longitudinal guiding system for the lock can be accomodated under the barrel outside the locking region, in particular between the fixing rail (19) and the fixing tongue (11), which makes it possible to reduce the length of the gun. The length of the gun is further reduced by means of a downward facing notch (53) in the locking bush (17) through which the tip of the bullet can pass.

摘要： A riot-gun comprises a gun body (10) with a breech block (16) having a snap fit arrangement (34) for releasably mounting selective barrels, for example barrel (32). The barrels are interchangeable and can be of different lengths to be suitable for firing different types of ammunition. One or more of the barrels is also adapted to receive a barrel insert which enables the riot-gun to fire ammunition of different calibres. The riot-gun is therefore adaptable to fire ammunition such as large- or small-caliber flare rounds, baton rounds, gas cartridges and live ammunition.

摘要： A firearm with barrel interlock system for a rotary mounted quick coupling barrel assembly. In one embodiment, the firearm includes a receiver and barrel assembly rotatably mounted thereto. A bolt carrier supporting a bolt is slidably disposed in the receiver and axially movable into and out of battery with the barrel assembly. The barrel interlock system may include a first barrel anti-rotation locking element disposed on the barrel assembly and a mating second barrel anti-rotation locking element disposed on the bolt carrier that is engageable with the first element. When mutually engaged, the first and second locking elements form a meshed relationship and prevent rotation and removal of the barrel assembly from the receiver. In some non-limiting embodiments, the locking elements may be in the form of a protrusion and complementary shaped recess.
