CMMG is the manufacture but the MK-3 and it's 18" brother the SASS can only be purchased from CDNN Investments
. CDNN does not sell guns online but can be reached at 800-588-9500. I've spoken with at least two employees and both were very helpful and courteous. When I last spoke with them (week of 11/7/2011) black was the only color available despite their ad saying Olive Drab and Dark Earth were also available. Ad, see page 30.
There was also no ETA on colors other than black.
Being that you can purchase any other CMMG made part from their website, http://www.cmmginc.com/
, I'm not sure why the MK-3 and the SASS can't also be purchased directly. Hopefully CMMG will give us some insight.

The overall fit and finish is very good. The upper and lower fit well together, with only a slight amount of play. This is my first manufactured purchased rifle in quite a while and I was impressed with it.
Sorry, for the crappy P&S camera pics, it's the best I have right now.
As it came out of the box (minus or plus, depending on how you look at it, the bottom 2" rail section I installed).
Lower section - Seems to be your typical AR-15/variant lower. The castle nut is not staked. The MOE grip does not sit completely flat on the back of the lower, there is a slight gap between them.
The plastic disc of the end of the buffer spring was different....
Upper section - It took 4 screws (two different sized allen heads) to get the FF tube off. It looks like it takes four more bolts to get the barrel nut. The gas key is staked.
If anyone has any question please let me know, I'm happy to try to help.
I hope to get to the range tomorrow for the range report portion.
