I have an over/under Mossberg Maverick 12 gauge and adapters to shoot .22 and .32 from it. The adapters are accurate, but the issue I have is the POI is way off the POA and I cannot adjust the sights, however there is a pic rail I could mount an optic to. Since I have the ability to remove the adapter and use both barrels for 12 gauge, I would like an optic that can be zeroed for the .32 adapter but has a secondary setting that I can press a button and change to a zero for the shotgun. Does such a thing exist? A red dot or holographic sight that has multiple settings for different zeroes?
