I have no first-hand experience with these but I have used CMMG for other stuff with good results:

(I wouldn't mind one myself......)

I think CMMG stopped a while back. For G3 mag rifle your best bet would probably be to look at PTR (H&K clone). I've handled/ fired one and it was pretty nice. Outta the box with a match grade barrel.
What was wrong with them?

If you can, get them to chime in. I'd be real interested in their experience. I don't own one but curious as to what their problems were.
From what I have been reading folks have had mixed luck with these. I have read that some work great and others are horrid. Problems seem to be the mags not fitting right and not getting the machining right on the uppers.
Personally, I wouldn't buy a lower that took a magazine that the rifle wasn't intended for in the first place. I'd stick with DPMS or Armalite. Yes, you must use proprietary mags, but how many do you want? Mag prices for both have come down.
Pass on it. Seriously. Some people have had good luck with them, a lot haven't. I had a lot of FTFeed issues with mine. CMMG says that "some" of their customers have had issues related to tolerances on the magazine catch.
I sold an M1A and bought one of these rifles. Regretted it after a few range trips where it didn't work worth a damn. My lower went back to CMMG for store credit (bought a nice 5.56 CHF barrel and some other stuff instead).
I have a M1A again, and it works every time.

The lower has to accept the G3 mags, a DPMS pattern (or Armalite for that matter) standard lower will not accept them.

I have one. It ran well for the first 500 rounds, and then met exodious's rifle and realized it wasn't supposed to work. We spent a couple hours on the range swapping parts and neither rifle ever fed reliably. I got it to run enough to know I like the AR-10 platform, but it's going to have to be with some other lower & mags.
PatMcD, for me the issue wasn't cheap mags - it was available 20 round preban mags.

I too like the AR-10 platform. I salvaged what I could from my G3 rifle and built one on an NES 308 group buy lower that I found for sale a couple months back. The difference is that now this rifle works.
Edit: Just FYI in case anyone tries something similar (DPMS pattern lower) and finds that the magazines don't want to stay in the gun - try an Armalite AR-10 mag catch. The rod is a little longer to get more engagement with the release button, and the tab that goes into the slot on the magazine is shaped differently and a little longer. Using a standard AR15 magazine catch I could pull the mags out without hitting the release button. They're locked in solid now.

I have one of the NES lowers and it feeds bent, dirty, crappy, dented Indian 7.62x51mm crap ammo pretty damned well. For me, the biggest improvement in reliability was seen in switching from the C(rap)-Products mags to the Magpuls.
