I am not sure where to post this but i suppose this section will do and if its not the correct area I do apologize.
So not long ago i purchased a large lot of gun supplies, ammo, and other stuff and within this lot was 4 hollowed out grenades.
At the time i thought "Oh sweet grenades...". I have seen them at gun shows and such but i really don't know much about them or the legality of having them.
Right now they are sitting in the gun safe and each time i open the safe i wonder "WTH am i going to do with these?"
Here is a picture of the grenades (they are all hollowed out)
The pins are all bent do that you cannot pull them unless you really tried.
I live in Illinois and after a short amount of searching haven't found anything about their legality. I have seen some places say that to be legal they needed to be filled with something like cement but im not sure.
Also for those who know anything what else can you tell me about these?
