i picked up a spartan remington 310 20ga from a local shop. the previous owner didnt maintain the gun like they should have and i found some residue of some kind inbetween the barrels. how would i go about cleaning that out so no further damage is done?

try some hoppes barrel blast spray, and see if you can fit a thin rag in there and wipe it out.

Pipe cleaners work well too...
