That is cool.
I don't think caliber has anything to do with it. The feds simply made that up. The is Striker illegal because it was cool looking. :supergrin: The Rossi 28 ga is ok to be imported and here is 12 ga. Russian shotgun that is double action.As long as it stays under .50 caliber(which would only leave the .410 bore) there shouldn't be a problem. Also, since it looks to be a "sporting" gun there also shouldn't be a problem.
The Striker was a 10 round semi-auto(well, wind up,LOL) revolving shotgun with a folding stock and forward pistol grip, totally EVIL with no sporting use.LOL. :supergrin:
