G&G Armament have shared details of their new GM406 grenade 70R:
We’re adding some extra firepower to our arsenal with the new G&G GM406 70-Round Grenade! A durable, lightweight aluminum outer shell reduces the overall weight of the grenade. Easily fuel the grenade on the bottom with green gas. The new MG406 grenade fits most standard 40mm airsoft grenade launchers and sends a shower of BBs at your targets.
