I have to ditto Doyle . I have a couple of guns that I alternate between iron and optics.I don't think any of the Q-D mounts guarnantee repeatability.Experience has shown me that the mounts don't always return to the same zero. Close but not dead zero,maybe a 9 instaed of an X. They will put you on the paper and sometimes very close ,but why risk losing a match or missing the biggest deer of your life. Go to the range if you have taken the scope off and put it back on.
