40mm Y3 MK1 Automatic Grenade Launcher

Introduction

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.

40mm Y2 MK1 Multi Grenade Launcher

Introduction

The 40mm, Y2 MK-1 Six Shot Grenade Launcher is a lightweight, semi-automatic, shoulder fired grenade launcher for infantry use. It fires the widely used 40mm, low velocity family of grenades. The weapon is based on the revolver principle with a cylinder holding six rounds. A gas piston activates the cylinder, which is spring driven. The 40mm, Y2 MK-1 Grenade Launcher is fitted with an Occluded Eye Gun-sight (OEG), which means that the weapon is fired with both eyes open. The sight is operational in poor light conditions as long as the target can be seen.
