A quick reference for using irons to their upmost. I try to shoot 1/2 iron, 1/2 red dot throughout the year.
I have a quick detach mount for taking my Aimpoint off, the picitinny slots where it sits are clearly marked for re-mounting, and I always re-check zero to confirm.
Remember to use a spacer, or the correct mount when putting your red dot on. It's roughly 5/8" off the receiver. Bottom line is to make it so your irons are in the bottom third of the sight window of the optic. If mounted correctly, you can leave your irons up (which I highly reccommend) and they won't get in your way.
