Description The streamlined body is of high-fragmentation nodular cast iron and is fitted with a plastic obturating ring at the bourrelet.

The charge system consists of one primary cartridge fitted in the tailboom and horseshoe plastic secondary charges fitted around the tailboom in front of the fins. There are five increments in the

Charge 5, or Super charge, consists of the Primary plus five increments. This is only for use in high-pressure mortars such as the US M252 and UK L16A1 . It cannot be fired from low or medium pressure mortars such as the US M1 and M29 types. Manufacturer MECAR SA.
