Hello, I've been looking around all over trying to get a decent estimate of the value of a friend's shotgun I'm looking at. I haven't hunted since I was a teenager and decided to jump back into the fray this year. It's a Remington 1100 w/ full wood stock bought in the early 90's, 3" receiver, 30" full choke barrel. He's also throwing in a 24" cantelever rifled slug barrel, a tasco pro red dot scope and a synthetic thumb hole stock. He said there's a small patch where the blueing has worn a little but other then that looks and functions flawlessly. He's asking $450, thoughts? Thanks!
