Welcome to the site! I know you will like for SPS Tactical!
Are you sure that Bushnell doesn't have a side focus/parralax adjustment?
On the Bushnell website it says: Parallax setting from 10 yards to infinity
This would indicate to me that it is adjustable... but I could be wrong I guess.

I haven't seen one in person so I don't know for sure.
EDIT: I see you said "Side focus".... I didn't catch my mistake until I looked at the photo!
