Helix SFP 6-24x50. Comes with everything it came with. Absolutely nothing wrong with it. It was on a dreamline I sold. $250 shipped. Prefer paypal f&f, but I will take a bank check or money order.
If you are going to shoot pellets just get it and shoot it, the factory tune will be fine, but if you want to shoot slugs, watch utube and do it yourself, not difficult. Remember you are buying a “pellet” gun.
Get rid of the barrel tensioner. When you tension the barrel, I believe you bow the liner. I had same type issues, and went back to stock shroud, shoots straight again.
It was a CJ5. I do remember the book that came with it gave directions on how to plow farm fields with it. It would go pretty much anywhere I took it. I lived in the UP of Michigan and I sold it to a guy moving to Alaska for $2200 in approximately 1981. Perfect body with no rust.
