Definitions

• Grenade Launcher having a barrel which is arranged slidabiy relative to a trigger mechanism base
• the invention relates to a grenade launcher having a barrel which is arranged slidably relative to a trigger mechanism base between a front and a rear position, the barrel being locked in the rear locked position by a latch.
• the grenade launcher can be used either on its own or attached to an assault rifle.
• the barrel When a new cartridge is being loaded or a spent one is being extracted, the barrel can either be tilted to the side or moved forwards.
• a latch that is housed in the frame of the weapon is sometimes used to lock the barrel.
• the goal of the invention is to design a barrel lock that is simple both to manufacture and to operate.
• the guide rails pass through longitudinal holes in the barrel.
• the guide rails are interchangeably connected to the trigger mechanism base, preferably screwed on.
• the latch of a grenade launcher for right-handed persons is positioned on the left, side of the barrel and engages a recess in the left guide rail
• the latch When the barrel is in the extended position, the latch preferably rests on the front of the guide rail to prevent the barrel from retracting spontaneously.
• the desired extent to which the barrel is to be extended can be easily adjusted by selecting different lengths of exchangeable guide rails.
• the barrel guidance on the side guide rails and the locking by means of a latch positioned on the side of the barrel enable the weapon to be lowered in height, making it ergonomically more user-friendly when the grenade launcher is deployed under the host weapon or on a separate carrier.
• the side latch is much more intuitively accessible to the non-shooting hand.
• the grenade launcher has a barrel 1, which is slidably arranged between the front and rear positions relative to the base 5 of the trigger mechanism.
• Guide rails 2 are screwed to opposite sides of the trigger mechanism base 5.
• the barrel 1 is slidably mounted on guide rails 2 which pass through longitudinal holes in the barrel 1 .
• the latch 3 In the extended position of the barrel 1 , the latch 3 rests on the front of the guide rail 2 and thus preyvents the barrel 1 from retracting spontaneously, This locking of the barrel 1 in the open position makes it easier for the user to remove a spent cartridge that is otherwise difficult to extract, where greater force is required to remove the cartridge from the chamber.
• the latch 3 When the grenade launcher is being loaded, the latch 3 is pressed against the force of the unshown spring, causing the latch to disengage from the recess 7.
