Commando Archive

On the Acid Rifle tree, you can make these enchancment items. I can craft them all since I have Acid 4 done. What exactly do you do with these things. I make them and it is just a metal slab thing. I can examine it and destroy it.

Anyone know?

These can be given to weapon smiths to be added into grenades during construction. However they dont actually make grenades better so its just another worthless feature of the commando class.
