What type of AR are you building and at what distances will you be shooting?
I use a red dot without magnification on my ARs out to 100 yards or so. My ARs have 16" or shorter barrels (registered SBRs).
Seems like 3x-12x magnification is a bit of overkill if you're not going out several hundred yards.
