At the ranges the gun will likely be used in the dark, just shoot over top of them. Its just like shooting a handgun when you shoot over top of them, youve shouldered/presented the gun so many times in practice, youre just using a different index.
Peeps are great for "target" or more precise shooting in good light, not so much for other things. Ghost rings help, as does lots of "practical" practice, for when they arent the best.
