It's KAC and just that, no doubt they make a very fine product but you are paying for same name in there too imho. It's more expensive to civis, I don't think the .mil is paying 360 a pop for a rifle length FF rail. I saw some staggering figures once on the cost the .gov pays for it's issue m4's from Colt, it aint much, I think a fully functioning M4 sold to the .gov was under 300 bucks.
