US12578155 - Automatic firearm with pressure controlled inertia mechanism

An automatic firearm is provided, which operates with a system which unlocks the rifle with a certain force and makes it ready for firing again by using this energy, while the mechanism accelerates backwards with the force created by the pressure formed in the barrel after the weapon is fired, and the idle parts in the mechanism move forward due to inertia, creating create kinetic energy and includes apparatus suitable for this system.

The patent describes an automatic firearm that utilizes a pressure-controlled inertia mechanism to enhance firing efficiency by harnessing the energy generated from barrel pressure after each shot. This system includes various components such as recoil springs, an inertia weight, and a lever charging handle, all designed to optimize the firearm’s operation.

Claim 1

1 . An automatic firearm with a pressure-controlled inertia mechanism, comprising: at least one recoil spring located in side walls of a body, and a pressure-controlled inertial mechanism, comprising: a lock, a needle comprising a needle spring, a mechanism cover, an inertia weight, an inertia spring, a lever charging handle, and an inertia pin. at least one recoil spring located in side walls of a body, and a pressure-controlled inertial mechanism, comprising: a lock, a needle comprising a needle spring, a mechanism cover, an inertia weight, an inertia spring, a lever charging handle, and an inertia pin. a lock, a needle comprising a needle spring, a mechanism cover, an inertia weight, an inertia spring, a lever charging handle, and an inertia pin.
