Can a non magnified red dot sight have parallax? The reason I'm asking is because in the user manual for our Aimpoint M68 CCO's it states that they are parallax free past 50m. If the target is within 50m you have to have the dot centered in the scope and on target, but @ 50m and out all you have to do is place the dot on target (no matter where in the scope it's located). I know how parallax effects magnified optics but this doesn't sound like the same thing. If you have your head centered in the optic then parallax is negated...right? With these optics it only matters out to 50m. Am I wrong about this? Are they just labeling it incorrectly?
