Abstract
Conventional grenade launchers, loaded from muzzle have short barrel, short range and big recoil forces transmitted into frame. Claimed grenade launcher has longer barrel and part of recoil forces are self compensated. Invention gives possibility to use in grenade launchers more powerful and long-range grenades without increasing of recoil forces. Technical result is achieved by shot executing in manner "fire-out-of-battery" and using special cartridgeless grenade. For this, grenade launcher has composite barrel, one part of it can fulfill reciprocating movement both under action of gases of carrier and gases of grenade's propellant and grenade is loaded into moveable part only by rear part having rifling. Grenada charged into moveable part of barrel risen by hand lever into charging position. For shot execution moveable part of barrel is returned in back position. Shots' gases bypassed from carrier initiate both igniting of grenade's propellant and executing moving forward of moveable part.

6 For loading of the grenade launcher, the movable chamber that is consist of joined together HP and LP barrels, is pulled out into charging position by a charging handle.
A grenade is put up into LP barrel and is rotated thereby that a rifling of the grenade comes into a rifling of chamber. Fig 2, Fig 3 After that, the chamber is moved onto the shot position up to that the male union of the launcher puts into the inlet port of the grenade. Fig 4 In initial moment of shoot, powder gases from a gas operated weapon, which coming into the LP barrel of the grenade launcher, relocates forward a movable chamber and carries out mode "fire-out-of-battery" and, after that, they initiates a propellant charge in the grenade. Fig 4 When a propellant charge of the grenade is ignited, the grenade leaves the rifled chamber and realizes shoot out of LP barrel. In this time, under influence of gases of a propellant charge the chamber goes backward and partly compensates recoil force of this shoot.
