Sweet, I'm planning on building a C7A2 look alike at some point in the near future, what kind of tri rail do you have on there? It doesn't look anything like the UTG one I've been looking at.
Edit:
(So I don't flood the forum)
Here's an update on my CTAC, sorry for the piss poor camera quality if that buggers any of you.
Swapped my barrel assembly for a Madbull DD ~10 inch barrel, KJW threaded suppressor and a 365mm Koba hop twist
I want to call it a MK18 now but the only DD licensed stuff I have are the outer barrel and the lite quad rail.
