Garage Sales

[Gawdzilla Sama]

Got these (not the actually guns, but a handy image) from the yard sale across the street. Dude forgot some things when he took off with his new girlfriend.

I presume the bulbous part of the stock near the butt serves a purpose but what?

Storing gun powder. That's what it has been used for on my gun, but I haven't read the specs yet to see if that was a kosher application. I've had them for about six hours now. I'll update if any better information is provided. (Boss Lady doesn't want me waving them around the house, so I'll dig into them when she goes to work tomorrow.)
