looking for beefy 12 gauge barrels, don't need the receiver or any stocks, just a plain barrel. condition does not matter, can be scratched, missing blueing, cut down(nothing illegal), but the beefier the better as this is going to be used for load testing.
prefer a barrel that is easy to attach a homemade remote firing device, I do not want to be close during testing.
its a long shot but if any body already has a 12 gauge pressure test system I would be interested in that.
