摘要： A locked breach, gas operated long action firearm capable of firing heavy caliber shotgun or rifle shells with substantially reduced recoil. The gas piston and bolt carrier assembly are supported for recoil movement along a single guide rod which extends the entire length of the gun, permitting a longer recoil path resulting in reduced impulse due to recoil. The guide rod has a noncircular or radially-assymmetrical cross-section mating with a corresponding opening in the gas piston, so that the bolt carrier assembly remains in alignment over the entire recoil path. Separate close-bolt and open-bolt embodiments are disclosed, and the open-bolt embodiment is selectively capable of firing either semi-automatic or full-automatic while permitting reliable cartridge feeding from a box or drum magazine.
摘要翻译：一个锁定的违规，气体长时间行动的火器，能够发射重口径的霰弹枪或步枪炮弹，后退力大大减少。气体活塞和螺栓支架组件被支撑用于沿着延伸枪的整个长度的单个导杆的反冲运动，允许更长的反冲路径导致由于后坐而引起的减小的冲击。导杆具有与气体活塞中的对应开口配合的非圆形或径向不对称横截面，使得螺栓承载组件在整个反冲路径上保持对准。公开了单独的闭合螺栓和开放螺栓的实施例，并且开启螺栓实施例可以选择性地能够点燃半自动或全自动，同时允许从盒或滚筒盒中进行可靠的盒输送。

摘要： A sear actuator has a rotatable cylinder (770) mounted between opposing side walls of the receiver (1) and a slidable rod (771) extending transversely to the cylinder. The actuator is arranged so that in one position the trigger applies a rotating force to the sear through the slidable rod (771). In a different position of the cylinder (770) the slidable rod is moved out of the path of the force exerted by the trigger and the trigger abuts a wall of the cylinder and thus the sear is rendered inoperative.
摘要翻译：撞击致动器具有安装在接收器（1）的相对侧壁之间的可旋转气缸（770）和横向于气缸延伸的可滑动杆（771）。致动器布置成使得在一个位置中，触发器通过可滑动杆（771）向冲击器施加旋转力。在气缸（770）的不同位置，可滑动的杆移动离开由触发器施加的力的路径，并且触发器抵靠气缸的壁并因此使火花不起作用。

摘要： A hand weapon includes a weapon housing, a breechblock accommodated in the housing for reciprocating motion, a bolt affixed to the breechblock and a slot, having opposite longitudinal edges, provided in the weapon housing. The bolt projects through the slot. There is further provided a slot guard arranged for covering the slot. The slot guard comprises a first and a second sealing lip held by the housing along respective longitudinal edges of the slot and projecting outwardly. The sealing lips are, at least along outer edge portions thereof, in a face-to-face engagement with one another and are locally spread apart by the bolt.
