Magazines, what are these for?

[sillymike]

Ok, somehow ended with magazines that I don't have a gun for...
(can't have that, can we)

So anybody have any idea what kind of rifle I'll need to get in order to be able to use these? The short one will hold 5 rounds, the big one 9 rounds.

Thanks for your help,

Mike.

Tall one looks like a Squire Bingham, the short one looks like a mossberg.
