An EoTech XPS w/o any sort of riser will give you a true cowitness. An Aimpoint H1/T1 w Larue 660 will give you a lower 1/3 cowitness and the ADM will give you a true cowitness w/ the H1/T1 (the same for the PA micro).

When purchasing a mount it will tell you what type of cowitness you can expect.

This maybe a dumb question, why would you want a 1/3 lower co-witnes? I guess I'm not sure what's the purpose of co-witness is ?

I like a lower 1/3 cowitness. You look through the irons and there's your dot in the lower 1/3 of the optic lollipoped on the front sight. You can look over the rear sight and there's the dot floating over the front sight. Or you can fold down the rear sight and there again is your dot, above or on the front sight depending on your cheekweld. Best of both worlds, optics and irons.

Quentin, thanks for getting me up to speed. I'm sure I will be posting plenty of newbie questions. Thanks again

My EOTech XPS2 cowitness well with front & right Magpul Mbus2. No riser or spacer needed.

I put a BSA I got on sale through cabelas.com on my sons 10/22 with the archangel set up. He has the same sights that are shown in your picture. It works really good. He has all AR15 accessories on it.

This is a picture of his set up. I had to move the front sight back to the end of the hand guard. But it really works well.

PrimaryArms.com

Very good quality, low cost, fantastic (really exceptional) service and shipping.

You tube "primary arms drop toss fun" and see how well this dot holds up to punishment.

They make several models and offer the correct riser to cowitness with standard AR15 setups.

Only problem is not made in USA. But...not $350 either.
