摘要： A firearm using blowback action has a barrel which is movably mounted within a shroud which is fixedly mounted on the firearm's frame. A gas space is formed between the barrel and the shroud by a difference between the inner diameter of the shroud and the outer diameter of the barrel. At least one gas port provides fluid communication between the bore of the barrel and the gas space. During firing of a cartridge, pressurized gas in the gas space applies a force to the barrel which moves relatively to the shroud away from the muzzle end of the firearm to engage a slide or bolt, helping to move it out of battery and extract the spent cartridge casing. Gas is vented to the atmosphere through a gas vent defined between the barrel and the shroud in fluid communication with the gas space.

摘要： In an exemplary embodiment of the present disclosure, a target marker for a firearm may comprise a module having a first portion, and a second portion electrically connected and coupled to the first portion. A light source may be disposed within and electrically connected to the second portion. An optical component may be coupled to the first portion at a first fixed distance from the light source. A circuit board may be electrically connected to the light source via at least one lead, wherein the lead may permit relative movement between the circuit board and the light source and may maintain a second fixed distance between the circuit board and the light source.

摘要： A suppressed pistol has a breech block and a slide mounted on a frame. The breech block and slide are separate pieces, movable relatively to one another and the frame. A link extends between the breech block and the frame. The link carries a cam and a cam follower. The cam follower on the link engages a cam on the frame, the cam on the link engages a cam follower on the slide. Action between the cams, cam followers and the link causes separation between the breech block and the slide during operation of the pistol. The suppressor includes a container having baffle plates with truncated cones defining openings offset from the geometric centers of the baffle plates.

摘要： A firearm gas redirection assembly directionally directs discharged gases from a barrel towards a bolt frame, and uses the energy from discharged gases to force a bolt rearwardly in an action. The barrel has an elongated body, an inner barrel sidewall, an outer barrel sidewall, a rear end, and a forward end. The forward end of barrel forms gas vents. The barrel is fixed motionless on the frame of the weapon. A jet nozzle concentrically couples around the barrel and integrates with a bolt frame. The jet nozzle has inner and outer jet sidewalls and a jet nozzle edge. The inner jet sidewall and outer barrel sidewall form a gas space that is in communication with the bolt frame. Discharge of firearm forces high velocity gas through gas vents that form in the barrel, through gas space, and finally against the jet nozzle edge. This forces bolt frame rearwardly.

摘要： The present disclosure presents a firearm. The firearm includes a frame having a handle and a slide rail guide, the slide rail guide comprising two parallel grooves extending through a long axis of the frame, and a slide having a long axis, the slide comprising two parallel slide rails extending through the long axis of the slide, the two parallel slide rails operable for slidably engaging the two parallel grooves. The firearm also includes a first spacer, the first spacer fixedly attached to one of the frame and the slide, the first spacer operable to slidably engage the slide rails and the slide rail guide providing a first gap between one of the slide rails and the one of the grooves and a second spacer.

摘要： The invention relates to a self-loading-pistol which comprises a frame (1), on which is slidably mounted a slide (11) for reciprocating movement, through the front part of which passes a barrel (9), which is fixedly and non-movably mounted on the frame (1), whereby a recoil spring (25) of the slide (11) is mounted on the guide (26) arranged under the barrel and a mechanism for locking the slide (11) during the firing process is arranged in the front portion of the frame (1) under the barrel (9). The mechanism for locking the slide during shooting comprises a two-armed lever (16) arranged swingingly on the axis (17), on whose front arm a locking member (14) is mounted in a seat (18) and on whose rear arm the damping member (15) is mounted in a seat (19), as well as a two-armed locking spring (21), pushing the locking member (14) and the damping member (15) upwards towards their seats (18 and 19), the locking member (14) and the damping member (15) being situated in the path of the motion of the support plate (13) of the slide (11). When the trigger is pulled rearwards for shooting, it causes a lever (37) to block any pivotal movement of the two-armed lever (16) and to retain it in place with its front arm and seat (18) in the uppermost position. When the trigger is in its forward rest position, however, the pivotal movement of the two-armed lever (16) is not blocked, so that during manual retraction of the slide the front arm of the two-armed lever (16) together with the locking member (14) in seat (18) can be brought out of the path of the motion of the support plate (13) with little or no effort.

摘要： A blowback bolt for a firearm has a distal bolt face having an axially relieved lower lip closest to the ammunition magazine. The axial relieved lip strips the lead cartridge from the magazine by contacting the rim of the cartridge and scoops it into the counterbore seat on the distal bolt face while maintaining contact with the rim. Chamfered lateral guides at the angular extremities of an arcuate upper guidewall restrict lateral movement of the rim during the scooping.
