Abstract
A firearm single-shot bolt catch assembly and method of operation. The automatic firearm single-shot bolt catch assembly uses a tensioned spring that operates with a bolt catch. The tension from the spring works to pivotally articulate a plate in the bolt catch to a catch position, which restricts the recoiling bolt carrier group in linear path of the firearm. The tension from the spring presses the plate upwardly into the linear path to restrict the passage of, and hold, the bolt carrier group towards the rearward end of the firearm. This restriction of movement inhibits automated recoiling responses from the bolt carrier group, consequently creating a single-shot mode by disabling automated firing sequence of the firearm. Applying force to a lever that forms in the bolt catch overcomes the spring bias to displace the plate out of the linear path followed by the bolt carrier.
