The KB-P-65 (КБ-П-65) was an aircraft machine gun.
Shortly before the war began, the project of a rapid-fire aircraft machine gun using Ya.P. Avdysheva with movable in antiphase barrel and bolt, connected with each other kinematically, introduced the designer KB-2 Kovrov machine-gun plant Ivan Ilich Slostin, the author of multi-barrel "squall" machine guns. The outline design of the machine gun with the internal designation KB-P-65 (sample 150/3) was developed by I.I. Slostin at the beginning of 1941 in an initiative order and approved by the head of KB-2 VA. Degtyarev. After that, a technical design of a machine gun was developed, in which, besides AI Slostin, A.A. Dementiev, O.L. Bykova, N.P. Platonov, N.A. Bugrov, On May 12, 1941, the technical project was reviewed at the technical council of the People's Commissariat of Armament, as "Degtyaryov's aviation machine gun," while the name of the developer, Slostina, was not mentioned. It was noted at the technical council that the machine gun differs in its extreme simplicity in design, while the rate of fire is close to or even greater than that of the SHKAS serial machine gun, its low weight and dimensions, the minimum number of parts, with complete disassembly - only 78 including fasteners, and is of interest in the new principle of automation. As in the projects of machine guns SN Savin and Norova and Ultrakshkas Shpitalnogo and Komaritskogo in the machine gun KB-P-65, was applied a scheme of the barrel moving on the length of the barrel, in which its forward motion was carried out due to the gases withdrawn from it. Just as in the aforementioned samples, the gas tube in the machine gun was missing, and the stem of the gas engine itself was the barrel enclosed in the sleeve-cylinder. The barrel through the rack-and-pinion gear was connected with a gate having sectoral protrusions. The bolt locked the cartridge in the chamber chamber by turning by 75 degrees. The food could be carried out both from the loose tape from the SHKAS machine gun, and the cloth from Maxim on either side of the receiver. The machine gun had a gas regulator, allowing to change the rate of fire from 1300 rds / min to 1960 rds / min. At the same time, the weapon, being very compact (675 mm long) and lightweight - only 6.5 kg, was supposed to be used as an aircraft - in turret, wings and synchronous variants, and hand-held from bipods or machine tools, it was equipped with a light retractable butt. Several prototypes of the KB-P-65 machine gun were manufactured after the war began and after the martial law was introduced at the plant in connection with the emergency release and development of serial weapons, this interesting project was closed.
