I have this scope on my M14 with a 16.25" barrel.
Capable of sub moa accuracy @ 100 yards using Portuguese NATO surplus.

A shorter barrel is stiffer and has less flex otherwise known as barrel harmonics. Therefore , all other factors being equal , a short barrel should be more accurate than a long barrel.

True, right up until the velocity from the shorter barrel drops off.
