My Burris Pepr just broke so waiting for a replacement I grabbed some out of the drawer, all sets of rings I had were too low to see so I found a set of temporary Leupold rings at Academy Sports for $20. They are higher than the standard but still lower than preferred. The problem with them like any low rings is that grabbing the charging handle has become an awkward process. Granted, you don't need to charge the AR a bunch but something that can be a major pain if not thought out.
