What caliber is an American Gun Company double barrel shotgun with a number 5511 on all parts smaller than 20 gauge bigger than 20 gauge and where can you get parts for it?
Parts for an American Gun Company shotgun will only be found as part of another shotgun. Haunt the local gunshows for one that is being parted-out. As for the gauge (not caliber), did you mean "bigger than a 410"? There have been 24, 28, and 32 gauge shotguns made. Of these, only the 28 is still available in the US, but I believe 32 gauge shells may still be commercially loaded in Europe.
