Name: Automatic grenade launcher  

The 40mm Y3 Automatic Grenade Launcher (AGL) is a left-hand, belt-fed, long-recoil, open-breech grenade launcher with air-cooled barrel, in 40mm x 53mm calibre. The weapon is ideally used as a tripod-mounted support weapon for infantry as a vehicle or tripod mounted weapon, with a nominal rate of fire of 320 rounds per minute.

Functional Description

The weapon operates on a long-recoil principle. This means that the barrel group and the breech block group stay locked for the complete recoil distance of the breech block group. Linked grenades are fed through pawls into an extraction position above the barrel group. The barrel group movement and a cam profile in the feed slide activate the feed pawls. From this position the reciprocating breech block group extractors clips onto the base of the cartridge and extracts the grenade from the belt when the breech block group moves backwards. The grenade is then pushed down to align with the barrel group by means of a cam and follower situated on the right in the rear receiver. Empty cases are ejected through an opening in the bottom of the rear receiver.
