I don't know about that, but where the barrel mates to the receiver appears larger than my 20 gauge and 28 gauge receivers. They are kind of cool. I am thinking about getting it up and running and putting my 12 ga bbl on it. Just have to come up with all of the internals. The firing pin hole looks quite a bit smaller than the shotguns I have. Might try and find a used 220/219 and go from there. Jim
