It says turkey gun, but slap a modified choke in it and it's one hell of a goose/duck gun. If you can find one with a 30" barrel, so much the better.
I tried to buy one of those at the gunshow a while back, but the seller and I couldn't agree on the price. Thats a neat gun that would kick the crap out of the shooter. Right up my alley.
