There are AOW double barrels out there but they are pretty darn rare. Few double barrel receivers leave the original manufacturer without having a stock attached.
A few years back I was hunting for a AOW SXS and the few I found commanded a higher price due to rarity. I gave up in favor of a Serbu Super Shorty.
