MOA and MIL are the two commonly used standards of measurement for angular distance (distance along a curved surface) used in the world of scopes and reticles.  On a given optic, both the ranging hashmarks of a reticle and the windage/elevation adjustments will be weighted in either MOA or MIL.

When selecting an optic - you can choose a scope that uses MOA or one that uses MIL.

The MOA (also known as Minute of Angle)  standard is broadly popular due to simplicity.  1 MOA = 1 inch at 100 yards.  This is easy to remember and makes the mental math on adjustments and holdovers relatively simple.  Click adjustment values are typically 1/2 MOA or 1/4 MOA per click.
