Except the holster is a NFA Class III AOW, requiring federal registration and a $200 transfer tax. Failure to garners a $250,000 fine and 10 years prison.

Yeah, you're right. Just found that out myself.

FYI, the transfer tax on an AOW is FIVE ($5) dollars, not $200.

An AOW shotgun versus a Short-barrel shotgun means the AOW can't have a stock, only a pistol grip.

The main difference in ownership is a $195 savings.
