Sub=less than MOA=Minute of Angle=1/60th of a degree=1.06" @100yds. Sub-MOA means that the bullet will hit the target less than 1 inch off from your point of aim. MOA is the way accuracy is usually measured. If you ever hear someone talking about having a 1 inch group at 100 yards, they have a sub-Minute of Angle gun.
