Ok, cool. I'll get back to you when I get paid from my many invoices I have sent out.
EDIT: Seeing as you already have the Dark Earth upper (I'm assuming you want black too), I guess I could just buy that rifle. You could just build a black one when I pay you and sell me that one. I'd be down with that. PM me with the cost so I know what to put aside.

they are ARMS #70 (or 71, can not remember) flip up sights. that way they do not get in the way of your eotech holo sight. bugs some people, not yet sure if it will bother either of us, but we have the option of running with them up or down. Nidia will probably have an eotech, mine is likely to end up an acog type - but not yet sure.
there is a rail the entire length of the top - it is continuous from the upper assembly rail. the free float tubes have rail sections that can be added where you need/want them.
