Default EoTech - CoWitness?

Greetings! Seems as though the missus wants to hook me up with an EoTech holographic sight for my AR for our anniversary. Currently I have an MBUS rear flip up and an f-marked A2 up front.

I've seen...well, I've *heard* of co-witnessing. Can I do that with an A2 Will I need anything special to mount up the EoTech or is this your basic drop in? I've an a3 flat top.

I think eventually I'll swap the A2 for BUIS on some kind of rail... But don't want to scare the wife with too many goodies at once. :-)

Your expert guidance is greatly appreciated!

I'm pretty sure the EoTech's body is tall so blocks the irons - no cowitnessing.

It will work, i have the same set up on mine. You can still use the iron sights through the Eotech.

Sorry I gave bad info guys. I had seen a couple reports that it didn't cowitness. Can't trust everything you read!

Just got back from the range. Took the EoTech fitted AR out today and it co-witnesses. W/ the Troy BUIS it's a true co-witness. I forgot how much I like it.

this is all excellent data. No fear eitber. We all get to learn from out brothers in here, that's the best part.

MJ can I assume that I'll be able to have `true` cowitness on on my zombie killer as well? I've got the A2 f-marked sight and a magpul mugs in the back.

Can you explain `true` ...?

Thanks for the cool pics too guys!

Jeff

As the guys have stated it will work fine! The only thing is the Red Reticle of the EOTech will sit in the center and on top of the front sight post when zeroed, which is OK. If it causes you a distraction with the dot and the front sight being there in close proximity in the future. Get a Rock River Dominator II Rear Sight and Rail System. This is the one the DEA and others use. It will allow you to look over the top of both iron sights without the visual distraction of the rear and front sight. And will also co-witness should your optics fail you by simply lowering your head around 1/4 of an inch and looking through the EOTech Screen at your iron sights. Great combination!
