Abstract: FIELD: firearm, applicable in production of automatic weapon with various rate of fire. 
     SUBSTANCE: the transversal working surface of the breechblock assembly lug turns the larger arm of the joint lever and at the same time the smaller arm brings in motion the barrel in the opposite direction of the breechblock assembly motion. The moving barrel actuates the ammunition feed mechanism. The joint level at sliding of its larger arm on the longitudinal working surface of the breechblock assembly lug stops the barrel when the barrel recoil is completed thus preventing its reverse motion up to the completion of recoil of the breechblock assembly and the coincidence of the cylindrical working surfaces on the lug of the latter and on the larger arm of the lever. The ammunition feed mechanism, linked with the moving barrel, feeds the successive ammunition to the extractors of the breechblock assembly, which with the aid of the joint lower prevents counterrecoil up to the completion of ammunition feed to the ramming line. After the stop of the barrel in the initial position the counterrecoil of the assembly is completed under the action of the return spring. The barrel of the automatic firearm is installed in the guides of the box for longitudinal motion and provided with a spring. The larger arm of the joint lever in the lower part is made in the form of a cylindrical surface with the center in the axis of rotation of the lever. Lugs are made on the barrel and breechblock assembly, on the barrel- for engagement with the smaller arm, on the breechblock assembly - for engagement with the larger arm, having transversal, longitudinal and cylindrical working surfaces. 
     EFFECT: simplified construction of the weapon and improved its dimensional and mass characteristics.
