BB Grenade Tokyo Marui M320A1

This Tokyo Marui BB grenade for the M320A1 grenade launcher looks pretty real and it has markings in different places. Despite its realistic look, this 40 mm BB grenade has a lightweight design and you can easily carry a few around with you.

Essentially, the M320A1 BB grenade by Tokyo Marui functions as a magazine, with six loading chambers that can each be loaded with three BBs. After inserting the BB grenade into the M320A1 grenade launcher, the BBs are thrust forward using the gas stored in the grenade launcher’s grip. There’s a circular opening in the bottom of the BB grenade that evenly distributes the gas among the BBs in the six loading chambers.
