Not sure why they are so cheap? I almost never shoot mine casually except to verify the sights. After the seal was replaced it is deadly accurate out to long distances. Not sure if I would ever buy one in .177 though. Now if they had a .20......
All I know is I paid a LOT for mine this summer and WISH they were the price you can buy them today. If I knew then, what I know now I might have bought a B-28 or a TF 89 for my hunting. In fact for what I have in my 350 I could have bought BOTH with scopes for them as well!
Oh well, I have it now and I love it and you won't see mine in the bargain bin anywhere
