Some of the ring vortex using are from Seekins. I think. They look the same. So they are good to go.

(I sold this scope on rimfire central) I have Luepold 3x9 Mark AR scope I would let go for $310 shipped (mil-dot). Let me know it you are interested. I have the box. Also I can send pics on request. It has a very low round count (50 rounds 223).
