Sorry everybody for the off topic, but I'll keep it short.
I like the Benelli Nova/Supernova line of shotguns. One of the sponsors here has a Nova Tactical for sale at $550. If you are eligible for the military discount, that price goes down to $495. Sweet deal if you ask me. Receiver protected from the elements, chrome lined chamber (probably nicest machining available on the market), bolt and barrel also chromed, high quality ghost ring sights. Twin action bars, very good placement of the controls. Not so great trigger, but otherwise a very good platform. Comparing to Remington, one gets a great quality shotgun with no need for any upgrades at lower price that the "tactical" line of Remington Express. Parts are available even via Brownells. Mossberg also offers some decent choices those days too. I would go out and give different shotguns a try before committing to one brand. Good luck!
