Hey Guys,

I recently picked up an EOtech 552 HWS for my AR180B-2 and after checking it out I am overly impressed with the unit. One thing I am confused about is how the actual aim point works. After reading about the system on the internet I was under the impression that since the sight projects a image on a 3D plane the actual point of aim would always remain on the intended target regardless of the users eye position. After playing around with the sight yesterday I found that as I shifted my eye around view window the actual point of aim changed.

Would this not mean that everytime you aim that your point of impact would be different if you do not put your eye in the same line of alignment? Can someone explain to me how this works?

Cheers
 
Place your eotech on the table look at a target 50m away and move your eye around. You will notice the dot stays on target, at very close range it might move abit but not enough to screw your shot up.

It is better to try and keep the dot in the centre of the veiw finder, But not a must if your snap shooting.

Now go out and shoot!
Cheers

The farthest the reticle will ever be "off target", is the distance from the centre of the screen, to the outermost edge of the window. so about half an inch or so at any distance... well within the rifles inherent accuracy limits.


As Dsiwy said, aim the EOTech at a target 50 yards away, and then move your head. You'll see that it stays pretty much locked onto that target, as long as you can see the target in the viewing glass! :D

Its the same deal with most WELL MADE red-dot sights, although red-dot's do suffer from parralax. Aimpoints and Docter Optics are very close to on target because of the 2 laminated glass lenses, that use a reflection, and a refraction lens to keep the relfection of the "dot" parralel to the optical axis!

:D

if your rifle is off the same vertical axis between shots - THAT will have more of an impact on group size than the dot moving around as you move your eye around the holosight. I have both Eotech and Aimpoint - they are both capable of 1/4 " groups at 100 - I use bubble levels on my rifles when I shoot.Enjoy the Eotech - I love mine - nice tiny dot --
 
Thanks for the reply's guys

I just tried moving my eye around the viewing area on the EOTech at 50 +/- yards and you guys are right. The aim point doesn't move as much as I expected it to at that range.

This sight rocks.

Cheers
 
bubble level

I'm not familiar with this. Could you explain? :)

I have scope levels that clamp on my scopes or a bubble level that clamps on the weaver rail - You can see the bubble when you shoot to keep the rifle from canting - tighter group size is the result - the rifle is in exactly the same position with each shot. With square targets I also use a carpenters level when I put up the target. My scopes have the reticles perfectly aligned (bore sighters are no good) by using a plumb bob.Elevation clicks track perfectly vertical for long range shooting. I'll try and post some pics when I get back from the range - gotta out run the snow storm----:)
