I am graduating from hold over/under to an adjustable scope. 4X12 is enough power. But I use bullpup style air rifles and would like it to be semi-compact. I don't need 5 lbs sitting on top of the mounts. I have tried it with some of the compact scopes I use now but the internal system for adjustment varies when changing from one range to another. I think the scopes work fine for establishing a good zero but then changing to a longer range and back results in some fairly large errors. If possible I would like to keep the price in the $200 range. Maybe that's not possible or hopefully others have found something that works well for them. Thank You for any suggestions.
