Description
The CN1 Hand Grenade Riot ABC-M25A1 is a bursting type grenade used for riot control and to simulate casualty agents during training.
The grenade body is spherical. It is made of two plastic hemispheres cemented together. The two pieces together form a burster well and slider housing.
The fuze is a pyrotechnic delay-detonating type integral with the grenade body. The fuzing components consist of an arming sleeve, firing spring, slider assembly, and firing pin. The slider assembly contains a primer, pyrotechnic delay column, and a detonator. The grenade is assembled with a safety pin and pull ring.
Safety clips are not required with these grenades.
The CN1 produces a powerful lachrymal effect and is irritating to the upper respiratory passages. In higher concentrations, it is irritating to the skin, causing a burning and itching sensation. The onset of incapacitation is from 15 to 30 seconds and the duration from 5 to 20 minutes depending upon dosage concentration.
Functioning
The safety pin locks the arming sleeve to the grenade body through the slider assembly. It also retains the arming pin in a horizontal position. When the safety pin is removed, the arming sleeve is free to separate from the grenade body. The slider assembly is released and is driven against the firing pin. The firing pin initiates a primer in the end of the slider. The primer initiates the delay column which, in turn, initiates the detonator. The detonator shatters the grenade body, dispersing the agent.
