摘要： A bolt hold open (BHOA) catch assembly configured for operating with rimfire ammunition for use with a firearm including a receiver with an exposed receiving chamber. A BHOA housing is supported upon the lower receiver in communication with a receiver chamber in communication with a bolt assembly. A catch is supported in elevatable fashion relative to an end of the actuator housing and an end most and downward extending structural portion of the elevatable catch is capable of being manipulated by an externally configured and toggled bolt catch so that an inner pivoting end portion thereof engages the structural portion to raise the BHOA supported catch into contact with a forwardly traveling bolt, such as upon release of a previously retracted charging handle. The BHOA catch can alternatively be actuated upwardly by a suitably configured follower associated with an attachable and cartridge holding magazine, this again following a last shot hold open protocol.
摘要翻译：螺栓保持开（BHOA）捕捉组件，其配置用于与用于与包括具有暴露的接收室的接收器的枪支一起使用的火焰弹药。 BHOA壳体被支撑在下部接收器上，与与螺栓组件连通的接收器室连通。卡扣相对于致动器壳体的端部以可升降的方式被支撑，并且可升降的卡扣的端部最大和向下延伸的结构部分能够被外部构造和切换的螺栓卡扣操纵，使得其内部枢转端部接合结构部分，以使BHOA支撑的卡扣与向前移动的螺栓接触，例如在释放先前缩回的充电手柄时。可替代地，通过与可附接和盒式存储盒相关联的适当配置的跟随器可以向上致动BHOA捕捉，这又是在最后一次拍摄保持打开协议之后。
