Lựu đạn Airsoft V0.9 (Airsoft Grenade V0.9)

THIS MODEL IS STILL IN BETA

This is an spring powered grenade for airsoft. It works with a screw hanging of a ridge. If the grenade impacts something, the Screw is pulled down, and the BBs catapult out of the bottom plug. 

Hardware needed:
M3x20 (x4) 
M3x25 (x1)

The two halves, to secure the grenade are held on with hot glue. The “solution” sucks, and I have thought about using other methods, to hold them together. If you have a good idea to join the two halves together, I would love to know your ideas.

Be aware, that not all airsoft fields allow all types of grenades. Be aware of your local regulations.
My local field does allow my self build grenade.

Update to V0.9:

Bottem is now screwed on, stronger spring holder, easy reloading
