Abstract
A sear trip bar for use in an automatic firearm is disclosed. In accordance with some embodiments, the sear trip bar can be operatively interfaced with the bolt carrier and the automatic sear of the host firearm. The disclosed sear trip bar can be configured such that, upon sufficient displacement thereof (e.g., exhaustion of its stroke length) by the bolt carrier, the automatic sear may be caused to trip. Thus, the disclosed sear trip bar can be utilized, for example, to transfer the force of the moving bolt carrier during a given firing cycle to automatically trip the sear so as to initiate one or more subsequent firing cycles without having to release and again operate the trigger of the host firearm. The disclosed sear trip bar can be utilized, for example, in pistol-caliber and/or rifle-caliber automatic firearms.
