Here's a question - at the gun counter at work, they just received a couple of 590A1's. They have the heavy barrel, and 590A1 is stamped on the receiver. They have ghost ring sights, and the bayo lug, and come with 20" barrels. However, they have a regular stock, not a speedfeed version. The box says "590A1 Persuader", but I can't seem to find this one on the Mossberg website...the barrel is parked, but the receiver appears to be finished differently...any thoughts on this? The price is $549.99, which I thought was really cheap for a 590A1...
