All the BZO threads I could find are older and not relevant.
With the trend of longer FF tubes on ARs, resulting in longer sight radii, I was wondering if this changes impact at different ranges?
Reason asking is I have recently built a SPRish 18" upper with a 15" free float. And for those who participated in my Noveske blues thread, that one is equipped with a 16" barrel with 13" rail.
