Most of my mounts are true co witness. I like the lower profile and the dot on the post. I feel it is better than lower 1/3 but it's really a preference thing.

All useful and very helpful info guys.....thanks alot!!
I don't have an upper yet, but it'll be a flat top for sure...the bottom is a stag...I'm thinking of going the del-ton route, seems to be good quality with good price.
Where do you guys recommend purchasing sights, both reflex, and BUIS?
There's a ton of places online, so much that its almost discouraging looking at all the places....but then again, that's half the fun!! Lol

Like CHLChris, I've gone with bottom 1/3 cowitness but can see advantages for absolute cowitness too. If your rear sight flips down then absolute might be the best, maybe not as good with a fixed rear. No wrong answer, preference as you said. People should get familiar with both, it's hard to visualize until you actually compare them.

I decide what I want then Google the specific model #. If it's a place I trust I order from there.

Aimsurplus has been good to me. SKDtac is great as well.

You might want to give Palmetto State a look for an upper or BCM.

Hey guys, I have another question regarding iron sights. I just purchased a used cmmg flat top upper with a Samson front flip sight. I also have a primary arms m3 red dot with a cantilever mount. What rear flip sight do you guys recommend to use as co-witness... I think that's the right term, basically be able to use the iron sights through the red dot if it malfunctions or batteries die.
Thanks

get the Samson rear.
