ELEVATION: 1 'click' adjustment at 25 yards

1 moa = 1" @ 100 yards (2" @ 200 yds. 3" @ 300 yds and so on)

A1 Front Post (Round) 20" Barrel = 1/4" (1 moa)
A1 Front Post (Round) 14.5"/16" Barrel = 3/8" (1.5 moa)
A2/A3 Front Post (Square) 20" Barrel = 3/8" (1.5 moa)
A2/A3 Front Post (Square) 14.5"/16" Barrel = 1/2" (2 moa)

So, depending on your particular rifle type/front sight type, it's still going to average somewhere around 1.2 moa +/-
