BB Grenade Madbull M433

This 40 mm Madbull M433 BB grenade is designed to look like a real M433 grenade. The robust metal construction can handle some abuse and the filling valve for airsoft Gas is level with the exterior to prevent damaging.

The Madbull M433 BB grenade can be loaded with 48 BB’s of 6 mm and is activated by a primer-like activation that is pushed in by the firing pin of a grenade launcher.
