Patent attributes
A device for converting a semiautomatic firearm to a non-semiautomatic firearm. The device includes a bolt stop lever pivotally attachable to a receiver of a firearm, a spring configured to be installed in contact with the bolt stop lever and a firearm receiver such that the spring exerts a force on the bolt stop lever to retain the bolt stop lever in a first position, and, a bolt release mechanism operatively coupleable to the bolt stop lever and configured to pivot the bolt stop lever against the force of the spring into a second position. The bolt release mechanism is operatively decoupled from the bolt stop lever when the bolt stop lever reaches the second position. When in the first position the bolt stop lever restricts motion of a bolt of the firearm, and when in the second position, the bolt stop lever permits motion of the firearm bolt.
