A pressure controlled inertia system for automatic fire weapons is provided. The system enabling a lock, especially in automatic rifles, to be opened by using a kinetic energy of a mechanism and a sliding handle block, wherein the kinetic energy is lost by hitting a case, after an empty cartridge is fired.

A weapon system that includes a breechblock, which is formed at least by a breechblock carrier and a breechblock head, the breechblock carrier being designed so as to carry the breechblock head. To achieve the fact that forces acting upon the breechblock drive during the unlocking of the breechblock and the withdrawal of a cartridge casing are minimized or even eliminated, the breechblock head is freely movable relative to the breechblock carrier. To separate the breechblock with a breechblock drive of the weapon system during the recoil of the recoiling masses of the weapon system, a device is designed in such a way that a mechanical separation takes place between the breechblock and the breechblock drive during the recoil of the recoiling masses of the weapon system. During the forward motion of the recoiling masses, the mechanical connection between the breechblock drive and the breechblock is reestablished via the device.

An assembly for a modular, compact firearm includes a universal action and an interchangeable, non-reciprocating barrel. The barrel may directly mount various optical sighting systems and provide integral muzzle compensation and sound suppression capabilities. The firearm utilizes a universal action comprised of a slide assembly, breechblock assembly, recoil assembly, and receiver which mounts a variety of barrel assemblies and assembles into a variety of different grip frames. The action of the firearm utilizes a partially-locked breechblock which amplifies the inertia of a slide.
