We tested out the durability and the quality of the epsilon bb training grenade. We have dropped the epsilon from 6 meters and still not stopped working. The quality is really great and works every time again.
Have a look at our youtube video:
CNC 7075 Aluminum is the high grade standard in the market. We use this version because of the strength and durability. This airsoft bb grenade works every time you throw it. Easy to install and reliable as always.
