Aimpoint really parallax free?

[Texas Boy]

I've always read that Aimpoints were parallax free - which I assumed to mean if I changed the position of my head/eyeball that the scope would still show me the correct point of aim.

Here is a simple experiment that makes me wonder how true the is....place your Aimpoint equipped rifle on the ground or in a vise/rest/etc. Look through the optic and position the rifle such that the red dot is directly on a point of interest. Make sure you can look through the optic without touching the rifle. Now move your head slightly - the dot will move, showing a different point of aim - but you have not touched the rifle so the point of impact can not have changed. This is parallax error and I thought the Aimpoints were supposed to correct for such errors.

BTW - the Aimpoint I'm using is a CompM3 purchased new from LaRue - So I'm highly confident it is not a fake.

I guess this means that a consistent cheek weld is still a requirement for accuracy with an Aimpoint.

Mine work fine and stay on target. Just testing my T1. Make sure you are looking at something further then a few feet away. If its too close it will not work.

Must be that small angle, big angle thing - tried it at a longer distance and it was fine. Note - there is still some parallax at 10-20ft - but then there is significant offset between bore and sight line at that distance too.

Thanks!

i think they're parallax free past 50 yards?

No optic is completely parallax free.

I think the point of saying "parallax free" is to highlight how much freedom of movement is really allowed.

Aimpoint should not state the following:

'2. Point of aim is point of impact
Aimpoint sights are parallax free, which means that the visible dot remains parallel to the bore of your firearm no matter what position your eye is in relative to the sight. This means that you never have to worry about centering the dot inside the sight. When the dot is on target, so are you.'

So Aimpoints are not parallax free in ranges where a red dot sight would be most useful.

They are 'practically' parallax free for a combat sight.
Read the Raptor dude's response down a ways. It's the correct response.

Thanks, but it's like stating that the food is organic/ non-GMO when it's not. Aimpoint should be more precise about it. From these notes, I would say that Aimpoint's design keeps parallax to a remarkable minimum.
