RE: Rem 11-87
I have the sportsman model in camo and I love it. It's is chambered for 3" like chaselton suggested. I don't have a problem with that and I picked mine up at Wal-Mart for $549.
Also I couldn't agree more with chaselton about the extra O rings. I don't think that mine have ever failed while the gun was operating, but I've had two that were broken when I took the gun apart to clean. I think that they broke while I was removing the fore grip and barrel, but can't say for sure. The gun has never not fired which is why I say that.
I must say though, if you had the money, browning is the way to go. I helped my buddy break his down, and it puts my 11/87 to shame. All of my internal parts look like stamped crap compared to that of the browning. All of his parts looked machined. That said, the gun shoots great, so I guess that is what really matters. I guess you get what you pay for.
Good luck,
