Description
This grenade consists of a fragmentation type body similar to the Hand Grenade Mk IIA1 assembled to a fuze and stabilizer assembly similar to that for the anti-tank and practice rifle grenades. The stabilizer and fuze assembly threads into the grenade body.
The fuze is a simple impact type. The striker is held away from the detonator by a safety pin and a creep spring. The safety pin projects through the fuze body and clamps around the stabilizer tube. When the pin is withdrawn, a drop of two feet, nose-first, to a hard surface will cause the fuze to explode the grenade. Detonation will not occur upon impact with water, mud, or soft sand. This grenade is designed primarily for use against personnel.
Functioning
The grenade must be placed on the launcher before the safety pin is withdrawn. The safety pin is removed before firing. When the grenade is fired, set-back holds the striker away from the detonator. On impact, the striker overcomes the creep spring .and hits the detonator.
