You will always do better by selling parts separately. Rifle is used. The small pics are hard to see. I'd use postimage or imgur, so guys can see it better. Gunbroker prices are pretty accurate. Look to see what they have sold for there. I can't remember what they sell for new, I haven't looked at one in a couple months. $2,100.00 or something like that??? I saw one that sold on GB for $1,600.00 and it was "factory new". It's easy to check them and get a good average and then decide if you want to let it go for that much.
