Big Dog: Just saw your post. I have Gold Cup that I use for Bullseye competition. Long ago, I learned to take a look at what the winners are shooting and then go with that. They use Red Dot sights unless the match rules - like a Leg match - say differently. Lately I have a JP sight on a pistol grip mount. If I want to use the iron sights, they are still on the gun. If I want to remove the mount, it's just two screws. I have not, to this point, had a problem with recoil causing a zero change; if that happens, I'll go to a base that mounts into the rear sight cut.
One note extra - if you have never used a red dot sight, expect a period of adjustment. When I went to it, my scores went down at first. Part of the issue is that, while iron sights can give that illusion that they are not moving, the red dot is ALWAYS moving. Getting used to that and minimizing it is the issue.
