EOTech+riser for lower 1/3 + magnifier + BUIS, what to do... (riser mostly...)
I've been reading, and reading, and I just can't put it together properly
I currently have the EOTech and the magnifier is en route. I'm trying to figure out what else to purchase to make this all work together.
I have seen a few photos of the YHM riser along with a LaRue F2S mount for the magnifier and a folding BUIS of some sort used in conjunction. The few rifles I've seen using the above method have a "monolithic" upper rail, so it's not an issue for them. I'm worried it would be for me. My AR has a MOE forend, and I have no desire to change that now or in the future.
Will the LaRue or ADM risers allow me to fit them all on there? Will the YHM work where I don't think it will?
Failing any other option, I'll just have to learn to tolerate absolute cowittness for the time being.
Thanks for any and all help
Which model of Eotech do you have?

511... got it in a trade. don't judge me
No judging here.
Check out Kyle Defoor's blog here:
He's using an XPS model in the link above along with a LaRue riser.
I guess the question in your case is if the front of the 511 (while mounted on the riser) will clear your handguard. I think it will, but I'm not 100% sure.

Thanks, the blog doesn't show me what I need, but was very helpful. I think when it's all said and done I could sell the 511 and buy an EXPS2 for about as much as it would cost to make the 511 work for me here. The difference would be less than one shift of overtime anyway
For anyone accessing this thread otherwise, Using an amalgam of photos gathered from around the net, I have figured out that the YHM riser needs a minimum of 8 rail slots to go from the forward stabilizing post to the actual clamp. the Troy BUIS leaves the T2 slot open and the YHM would cover past T6 from the front leaving T2 through T5 open. I haven't found any info on what flip mounts would fit, but I also haven't looked. This is also presuming that my counting is correct. I'm going to look into the Used EXPS market. Hoping for a 2-2 model.
I run a LaRue riser under the 552 on my duty gun.
And? Do you run a magnifier? A rear BUIS? Does it all fit comfortably?

You talk about "tolerating" absolute co-witness as if you are sighting through the Eotech, focusing on the FSB. Try putting some tape over the front of the glass on the Eotech after you get it zeroed.

I had a 552 on a YHM riser and a G33 magnifier behind it. (Colt 6920 with Magpul MOE like yours) The YHM riser just barely fit on the receiver rail with the G33 mounted behind it. The front of the YHM riser will fit on about half the Picantinny rail but the set screw portion behind it had a firm grip, so I think it was OK, I shot it with no issues. The magnifier comes with a 7mm riser which I used as well. The G33 clears the Magpul rear BUIS with no issue.
I ended up selling the 552 and bought an Eotech EXPS 3.0 which is shorter and has a built in 7mm riser so now it's not even an issue. I ended up putting a DD Omega X rail on my 6920 so now rail space is plentiful.
The YHM riser and a G33 magnifier will work on a flattop with no extra Picantinny rail in my experience, if just barely.

I'm digging Defoor's blog.
