Hello,
I just got an Eotech 512 A65 Rev F, and am wondering a couple of things about it.

I noticed that if I move my head around, the reticule moves around too, even if the rifle does not. I thought there was supposed to be a consistent point of impact b/c of the nature of the hologram. That didn't make sense to me, since I can't see how that would work.

So, do I need to maintain a consistent cheek weld with and Eotech just like a regular scope? How do you do that since there is no real reference point?

I tried googling some of the above, but didn't find what I was looking for, just marketing drivel and not real life user info.

Thanks in advance,
Mike

no mater how you move your head, and no matter how the reticel moves inside the optic wondow, your point of impact will not change. its call parallex free.

foucs on a point with your reticel, move your head around and watch the reticel move but still stay on target.

shoot with both eyes open. even though the reticle appears to move, your shots will stay on target regardless of the reticle's position in the window.

OK, so I tried that - it apparently was deceiving for me since I was looking at targets in the same room basically - plus I think I was changing the angle of my head rather than looking the same direction. It makes sense now.

Thanks for the replies - can't wait to take it to the range and try it out.

Is there any special trick to zeroing it? Instructions sound very similar to any old scope.

not really any special tricks, i suggest a 50 yard zero, that'll put you within an inch out to ~200

3/8" riser, cowitness above your irons.  This way your eyes aren't confused by both sights in the exact same spot.  You'll inadvertently try to line your sights up... and that slows down your holographic sight (that is best used for rapid engagements).  The riser gets your dot up and out of the way so your eyes can focus on aligning the dot on your target, not dot - front sight - target.

Keep both eyes open when you shoot.

Zero at 50 yards and like Zak said, you stay pretty flat all the way out to 200.  if you shoot at 300 you're gonna be low about 10 inches, which is really easy to remember...

If he's at 300 just aim at his shoulders or upper chest and you'll still hit center-mass.  If you shoot center-mass because you forget to hold-off... you still hit him in the tops of his wheels or lower abdomen.

Set your sight as far back as possible.  Short answer for why... it's to offset parallax.  Likewise, I'd recommend using a cheek-stock-weld further back on the stock (rather than nose-to-charging-handle).  Doing this will open your peripheral vision more and actually make you more accurate by increasing your sight radius.  
With a close combat optic the rear sight for your sight radius is your eyes, so... increase the distance between the two and you'll receive a truer point of aim.  
On an M4, I like to fully-extend the buttstock and rest my right side of my moustache on the lip at the front of the stock.

Oh, and use lithium AA's whenever you can.

ETA: As much as cheerleaders like to claim, EOTech's are not parallax-free... just "parallax-unnoticable" even Aimpoints have parallax...  Yeah, I know what the website says.

Thanks again for the replies!

I have a RRA dominator mount coming from a guy off the Fal Files that will raise the Eotech a bit.

I prefer to have the stock mostly extended on my Wife's M4gery as well ... mine has a fixed A2 stock so no worries.

Thanks again!
