Hey all, I just wanted to say that I recently purchased the MK4 RCE upper by CMMG. Not having owned any of CMMG's products before, I was reticent to order this upper as it is a brand new model for 2014. I must say, I am very happy I made the decision to do so. It is a quality upper: mid-length gas system, 7 twist barrel with a brake on it that appears to be like almost like the Ops, Inc. in appearance/design.
The upper has the newer RKM 14 handguard, which has the key mod system. Rifle has a great balance to it. I am just in the limbo of deciding which optics to throw up on it, but I am thinking an EOTech is in the works.
CMMG, if you see this post, can you speak to the details of the barrel on this particular upper? Is this your own barrel, are they CHF, any other details, etc, etc...?
Thanks all very much. Looking forward to shooting it here in the not-too-distant future...
