Can the Eotech, Acogs or Elcans handle it?
I would stay away from optics that are specifically designed to be mounted on AR-15-type rifles, e.g. Elcan, ACOG, or EOTech. Any of these will have a ridiculously high offset from the bore.
For a red dot, you want either a miniature one that can bolt directly to a rail or a 30mm Aimpoint in a low ring. Likewise, any magnified optic should be mounted as low as possible. Most mounts for the M14 have quite a bit of height as-is.
