Remington 870 Express Tactical - This model is really hard to get these days! Its the 18 inch combat shotgun with XS ghost ring sights (factory installed) and the barrel is threaded for rem chokes. It came with a breacher choke, I put a full choke in it. The pattern on this thing is extremely tight within 25 feet. I have pimped it out with a Mesa Tactical 8 shell carrier and Urbino stock. There is a ton of marks on it around the ejection port from combat loading. The gun has been fired about 4-500 rounds at the very most, and mostly field loads. Its seen more non-fire training than live fire. $625 shipped.
EDIT: Comes with the original box and manual and the original synthetic butt stock.
