I love mine. They're right to spec. I have one CMMG complete rifle, and bought two more CMMG lowers to build up. The parts (used DPMS parts kits) went right in without a hitch and I have CMMG uppers on order for them.
I'd recommend them without hesitation at all- they're every bit as good as everybody else's. Keep in mind that the lower isn't as big a deal as the upper (specifically, the barrel and bolt carrier group) when it comes to accuracy. So long as the lower is built to spec, it really doesn't matter if it is a CMMG, LMT, Bushmaster, DPMS, or other. Colt is really the only one who does funky things, and their takedown and pivot pin holes are drilled larger (well, the Vulcan/Hesse/whatever they call themselves now aren't built to spec, but that's another ball of wax).
