It has come to my understanding that 12 ga shotguns (since the bore is larger than .50") cannot have a mag over the size of 10rds or it no longer falls into the "sporting purpose" category. But I have seen an ar upper that is a belt fed shotgun. Since you register the lower, is it still considered a rifle since it is registered as one? If so, can it have a 16" barrel instead of 18"? Also, is that automatically a destructive device regardless of mag limit since it fires a round larger than .50"?
Another question I had is what is the legality of an under-barrel shotgun attachment (the "masterkey")? If it comes from the factory as an AOW (so we don't run into the SBS problem) would it be legal to have one mounted? Or would we run into a problem with a combination gun? But it they are registered as two separate weapons would it be legal to have them mounted together since they are both registered separately? Just a few questions I had. Thanks in advance for any help
