This is virtually new and was mounted on my backup F-TR w/ Burris Signature Zee rings (left no marks at all - nylon inserts) that I sold 2 weeks ago.
My reason for choosing this reticle is to keep it simple and uncluttered for target use, but with the side focus I can conveniently de-focus slightly to read mirage. This keeps you in position and not moving back from a spotting scope.

Thanks for considering it,
