I had an R7, ordering another one to be used as my primary along with a Duck. The redux I have that has been modded by CJ shoots great, and the only reason I'm selling it is because of the Duck hopefully being shipped next week. I think I'll sell my boxgun too, it just sits there on my wall wanting to be played with, but after getting an R7 - I don't think I ever will play with it.
Get an R7 with all the goodies - you won't regret it! The Redux and VKC are great guns, don't get me wrong!
