Bull pup gun trigger mechanism

Bull pup gun trigger mechanism

Invention relates to weapons. Trigger mechanism comprises trigger, lengthwise link arranged along left inner side of breech box under structural web and above autorelease and trigger pins. One end of said link is connected with trigger and opposite end is connected with adapter fitted on the pin of standard trigger. Or, directly with standard trigger adapted to link connection.

Lockwork

Lockwork

Automatic gun lockwork comprises sear with trigger, trigger pin, drop-in auto sear fitted in trigger pin, decocking and spring-loaded automatic release trigger, firing spring, trigger pin, spring-loaded automatic release with sear and spring-loaded release pin. Trigger is composed by L-like leer with stepped full cock to interact with spring-loaded U-shape automatic release with its pin arranged between trigger pin and hammer pin.

Automatic gun

Automatic gun

Automatic gun comprises barrel (6) sliding in breech frame (1), gas vent gear (35), spring loaded bolt carrier (19) with bolt (20), buffer mechanism (118), feed mechanism (2), lock mechanism (17) and trigger mechanism (18) in case with sear (84), barrel angular shift device (5), cover (176) with strap (183) and guides. In incorporates the assembly arranged under barrel (21) and barrel and recoil part residual pulses damper (16). Lock mechanism (17) has fire springs (70, 71) and trigger assembly (69). Guides (22, 23) are composed of the left and right assemblies. Trigger mechanism (18) consists of trigger (90), lever (93), release plate (92) with pin (97) and trip (99) on pin (103), seat (84) with bearing surface (88). Trigger (90) interacts via ledge (95) of lever (93) with displacing release plate (92) fitted in release mechanism case (82). Pin (103) and trip (99) serve to interact with bearing surface (88) of sear (84) which interact with trigger assembly (69).

Weapon trigger mechanism

Weapon trigger mechanism

Trigger mechanism is installed on small arms of a carriage-mounted gun of a bullpup configuration with prior recoil of a firing device inside its guide bed, equipped with the right and left gun handles. A trigger mechanism comprises the following: a figured spring-loaded slider trigger element with two triggers, a muzzle ledge, acting at a transversely moving spring-loaded strut of a full bent in the front position of the firing device, and a breech ledge of the trigger element acting at the strut. The breech ledge is installed on a spring-loaded cam available on the slider trigger element. The breech and muzzle full cocks of the slider trigger element are installed at the distance, the value of which provides for locking of the spring-loaded hinged cock in the cocked position immediately after the first shot in the "fixed" burst firing mode. The trigger mechanism comprises a cock moderator to reduce the firing rate in the "burst of arbitrary length" mode. The longitudinal figure slider trigger element is placed on the carriage-mounted gun equipped with a basic longitudinal metal element, which carries the movable firing unit and metal bases of weapon gun handles. The return spring of the trigger element is placed on a breech rod of the slider trigger element with a rest of the muzzle end at the crank transition of the trigger element, and of the breech end - at the breech wall of a seat for this spring.

Firearms counter-recoil mechanism

Firearms counter-recoil mechanism

FIELD: firearms. SUBSTANCE: counter-recoil mechanism comprises a pullback string (1); a step-like connecting rod (2) divided into attachment area (3), fixation area (4) with side planes (5) and thrusting area (6); and a coupling (7) with a slot (8) and edgings (9). The size (10) of the attachment area section is smaller than the coupling (7) slot (8) width, while the size (11) taken on edgings is larger than the coupling (7) slot (8) width. EFFECT: mechanism operation reliability increase, design simplification. 2 cl, 4 dwg

Automatic small arm

Automatic small arm

Invention relates to anti-personnel small arms. Hammer retarder represents plate 15 interacting with hammer tail and has one end fitted on the axle. Plate 15 stays in permanent contact with tail of hammer 4. Fire rate regulator is made up of plate 17 fitted in the same axle to interact with eccentric washer 18 to adjust force spring 16 acts on retarder of hammer 4. Washer 18 is arranged between plates 15 and 17. Hammer tail is furnished with roller to allow plate 15 with said hammer tail.

Automatic gun

Automatic gun

Invention relates to small arms and represents an automatic gun that comprises barrel, breech box with bolt, hammer with spring, trigger with spring, automatic fire sear with spring, single fire sear with spring, firing lever with spring, shots counter with spring and safety lock and four-position fire selector: "safe", "single fire", "limited burst" and "burst". In "single fire", fire selector moves trigger lever and automatic fire sear out of engagement with firing lever, breech frame and trigger. Single fire sear stays in contact with trigger, breech frame and cock. Note here that shots counter is set into position whereat one of its ledges stays in contact with single fire sear. All ledges of shots counter stay in contact with single fire sear when in "limited burst" position. In "automatic fire" position, fire selector moves single fire sear and shots counter out of contact with cock, trigger and breech frame, while trigger lever interacts with breech frame in its counter recoiling between locking the bolt and coming into breech frame extreme front position, with single fire sear after breech frame comes into extreme front position and with cock after it comes off the sear.

Small-arms trigger mechanism

Small-arms trigger mechanism

The small-arms trigger mechanism has a spring-loaded sear, intermediate sear and a spring-loaded trigger. The trigger is made hollow. The intermediate sear is fastened inside the trigger on a common axle, it is made double-arm with one arm positioned vertically, and the other-horizontally. The vertical arm of the intermediate sear is permanent engaged with the spring-loaded sear for engagement with the front wall of the trigger. The horizontal arm is made for engagement with the lower edge of the trigger front wall.
