I am thinking of mounting a EOTech 512 on my flattop M4.  I am not sure if I want to absolute co witness the front sight or raise it up over the front sight.  If I mount it directly on my flat top what will I see?  Do I need any spacers, risers etc.  Any input on different configurations would be appreciated.  Thank you

as seen from CMMG's website

If you mount it directly on the flat top, you will co-witness.  If you put in on a riser (YHM / Larue), you should be at the top 1/3 of the window.   If you use a Dominator, you can rise it to eleviate neck angle but you will co-witness when you drop your head.  It's a bit hard to explain unless you try them all out.  Most people just mount right on the flat top.

This has been covered a lot and there might even be some pics of interest to you in the BUIS thread tacked above!

Here is my EOTech mounted directly to the upper receiver of my M4gery, and two pics to give you an idea of the sight picture using a CCH BUIS.

I have mine mounted directly on the rail as I prefer absolute co-witness over lower 1/3.

Still haven't decided if I want to try the GG&G Accucam.  I do like the QD ability but so far the standard thumbscrew has been just fine.

I have been trying to decide on the Accucam myself.  How will it effect my co-witness?

It will keep it the same as the Accucam is the same height as the original mount.

The Accucam, according to the website, won't raise the EoTech any, so you'll have the same cowitness as with the factory screw.

Are you planning on removing the EoTech frequently, like to swap another scope in its place.  If so, consider a mount.  If not, skip the mount, and leave it in place.

EOTech 512 mounted directly on the flattop.

The Accucam is not a "mount".  It simply replaces the Eotech screw tensioner with a cam tensioner, hence the name Accucam.
