hooligan1, adjustments are adjustments regardless of whether up/down or left/right. If you think a scope knows which way is up, you're wrong. If you've ever looked at an AimPoint, you'll see those turrets are marked for both orientations. I've used several scopes for specific needs "turned on their side" and all work fine but you have to give some thought to which way is left or up.
Don't dis the optics under $100 unless you've tried each and every one available. There ARE good reliable scopes in that range.
