This is the 18.5 deep polished blued barrel found on Police model 870. Had this on a wingmaster with one mag tube shot through it. Its in very good condition but i must add their is some faint marks where i had mounted a 2" mag extension with a clamp, I must say very minor! Tried to take pictures but the glare and my camera wont show this. $150
Also have a like new Remington +2 shot Blued mag extension included extended spring, lock nut, and clamp. Had the same use the barrel has $50 shipped
ill take the extension..
