摘要： A firearm operating system includes a housing, a central pivoting member disposed within the housing, a trigger including a portion disposed within the housing and a portion extending outside the housing such that the portion of the trigger within the housing includes a hole and at least one finger that extends in a first direction from the hole. Due to movement of the trigger, the at least one finger presses against the central pivoting member to cause the central pivoting member to rotate.

摘要： A delayed rotary blowback mechanism integrated into a firearm bolt and carrier subassembly. A plurality of radial locking lugs are configured at a rear end of the bolt and seat within a mating profile of a barrel extension of the firearm in a fully chambered position. A plurality of chamfered locations are configured between the lugs and a receiving profile in the barrel extension for influencing linear to rotational motion of the bolt. A cam pin extends upwardly from the bolt and seats through a circumferentially directed slot configured within the bolt carrier. Upon initiating of the discharge cycle, signaled by the round traveling through and out the end of the barrel, the chamfered configuration results in the bolt and cam pin rotating within the carrier and the lugs subsequently separating from the barrel extension, with the bolt and associated carrier retaining sufficient inertia to cycle through the discharge cycle to the set position concurrent with reloading a subsequent cartridge.

摘要： A firearm with a tool-less adjustable trigger pull. The adjustment may be facilitated with a thumb rotatable wheel for tool-less tension adjustment of a trigger tension spring. The rotatable wheel may be accessed by snapping a trigger guard away from a stock of the firearm. Accordingly, the force required to actuate the trigger can be adjusted to the user's preference without having to remove the trigger assembly from the stock, and without need for external tools or accessories.

摘要： A firearm (1) includes a detection system (10) suitable to detect a configuration change of the firearm from an initial configuration. The detection system (10) includes a detection device (100), on the slide (20) suitable to be moved, starting from an initial position, to a detection position in which the detection device (100) detects a configuration change of the firearm. An idler device (200) on the slide (20) engages with the detection device (100) which moves the idler device (200). The detection device (200) includes at least one primary sensor element (250), a receiver device (300) on the main body (5) suitable to receive the information of the configuration change of the firearm from the primary sensor element (250) and at least a secondary sensor element (350).

摘要： A bolt action firearm that cocks the firing pin upon closing the bolt and includes a cam pin with dual heads for a high velocity rimfire cartridge. In one embodiment, actuating the main spring while closing the bolt, instead of while opening the bolt, more uniformly distributes the physical energy required by the user over the bolt actuation cycle. The dual heads of the cam pin provide symmetric reactive forces with dual cam slots, thereby preventing the cam pin from skewing or canting within the cam slots. A safety system is provided for the trigger mechanism and a robust connecting systems for the stock.

摘要： The automatic fire arm is provided with a bolt and hammer which reciprocate along the axis of the barrel. A first spring normally biases the bolt against the breech end of the barrel and a second spring normally biases the hammer against a firing pin which is slidably mounted within the bolt. A moveable retaining lever is pivotally mounted below the chamber in which the bolt and hammer are located. An upwardly extending projection is provided on each end of the lever which is extendable into the chamber through axially spaced apertures. A trigger mounted pin normally holds the lever with the rearmost projection extending into the chamber so that upon retraction of the bolt and hammer the hammer will be held in cocked position by the rearmost projection when the bolt returns to engage the breech end of the barrel. When the trigger is operated, the forwardmost projection on the lever will be free to move upwardly into the chamber only when the bolt contacts the breech end of the barrel, thereby allowing the hammer to force the rearmost projection downwardly out of the chamber so that the hammer can contact the firing pin.
摘要翻译：自动消防臂设置有沿着枪管的轴线往复运动的螺栓和锤。第一弹簧通常将螺栓偏压在枪管的后端，而第二弹簧通常将锤子偏压抵靠可滑动地安装在螺栓内的击发。可移动的固定杆枢转地安装在螺栓和锤子所在的腔室下方。在杠杆的每个端部上设有一个向上延伸的突出部分，该突出部分通过轴向隔开的孔可延伸进入腔室。触发器安装的销通常保持杠杆，最后面的突出部延伸到腔室中，使得当螺栓和锤子缩回时，当螺栓返回以接合枪管的后端时，锤将被最后面的突起保持在被锁定的位置。当触发器被操作时，杠杆上的最前面的突起将仅在螺栓接触枪管的后膛端时自由地向上移动到腔室中，从而允许锤将最后面的突出部向下压出腔室，使得锤子可以接触撞针。

摘要： A recoil brake or block mechanism for an automatic fire arm having a linearly reciprocating breech block. This mechanism includes a slide which is reciprocally mounted on the breech block. A two-armed lever is pivotally mounted in the housing of the fire arm and is adapted to coact with the slide so as to absorb a portion of the recoil energy. The slide has front and rear contacting surfaces and the two-armed lever has a pair of arms, each of which has a control surface which is adapted to respectively coact with one of said contacting surfaces. The center of gravity of the two-armed lever is located in the longer arm of the two-armed lever at a distance from its pivot support.
