M4A1 Clone, which CCO optic?

[TK-Hryciuk]

Hey guys, so I'm putting together an M4A1 clone and I have everything good to go minus a KAC foregrip and optic. My question is, which CCO optic does the US mil use currently? I know they used the Aimpoint M2 and switched to the M4 or M4s. Everywhere I read tells me M4s is the current issue but every picture I have researched has the M4 with the high battery compartment. It doesn't really matter to me, I am just trying to keep my build as authentic as possible. Thanks guys!

PS, will anyone be able to host a picture of the rifle for me when I get it set up? I use my iPhone and it's nigh impossible for me to get pics set up on here!

For photo's on a forum get the Photobucket app, it makes putting photos on forums super easy.

I had a comp M4s and I truly regret selling it. I will be buying another one in the future.

I just put mine together. I'm assuming you're talking about the M4A1 in the SOPMOD program (DD RIS II, KAC taupe front sight, Elcan SU-230, etc...). You building a block 1 or block 2 carbine? That'll determine which optic you are looking for.
