If you need MOA or sub MOA return to zero, get a mount that does that: LaRue, ADM, Bobro, et cetera. PEPR might or might not. You don't want to encounter the "might not" when it really matters.
I have both LaRue and ADM QDs and both hold well within 1 MOA after regular removal and replacement. I swap pre-sighted optics on the same rifle regularly for different missions and carry a back up pre-sighted optic in the event of a failure. These two companies can be absolutely trusted. So can Bobro, by all accounts, although I have no personal experience with their products.
I like LaRue if the optic is heavy and needs dual levers and more rail slots and tend to favor ADM when a single lever design is needed. But both companies make mounts both ways, depending on your mounting needs.
