Okay question for those that know parallax. I have the from outer ring off my VX-1 (4-12x) (which has no parallax adjustment) Looking at it - it looks like I could glue/lock tight the outer ring to the threaded ring with the front lens in it and adjust the parallax by adding lines similar to other scopes with the parallax on the bell. Couple of question: Any one know how much parallax the scope is capable of adjusting before running out of threads? Also for longer range, do I want the lens to go in or out? And last, will the scope be damaged if I screw up and unthread the lens and break the seal?
