ball bearing
I just recently bought a grenade launcher and a shell. I open the and i saw a small ball bearing in the plastic. I just wondering what does it do and what would happen if I take it off thank you.

You found a loose ball bearing in the package? Well the shells use 4 ball bearings in the valve assembly.

It's used in the valve assembly, to friction lock the release valve going up and down.
