Turn em into art pieces,,,
I once took an old dead revolver and filled it up with epoxy,,,
Then I made a shadowbox and mounted it with a 45 PRM record of "Saturday Night Special".
Gave it to my musician brother.
I also made a standing table lamp out of an old S&W Pump Shotgun,,,
Again I completely filled the workings with epoxy.
Sold it for $175 if I recall correctly,,,
That's more than I could have parted the gun out for.
Get creative my friend.
