What is the quality of the CMMG 16” M10 Mid-Length MedCon Upper? What is the stock bolt? Bolt quailty? I am looking at the rifle length rail with a lowpro gas block and flip up front sights. Will this upper mate well with a RRA lower? |

cmmg is good stuff and they do good work. I had them put their 14.5 lightweight middy bbl assembly on my m16 slick side receiver and the work is top notch. i almost went med-con but i decided on light as possible. i don't have one of their bcg's but wouldn't hesitate to use one. great thing is i had the upper back a week after i mailed the receiver. i figure 2 days in shop and the rest shipping. that is fast for a custom assembly. don't get the std. handguards, they not as nice as what's on my rra middy. color is a perfect match with rra. |

I love my CMMG stuff, but to answer this one question: I have three Rock River Arms lowers, and have the damned-est time getting CMT, CMMG or Bushmaster uppers to fit without a ridiculous amount of forcing. I'm not new at this, I know that "tight" is normal, but I mean "put the flat top on a flat surface upside down, lean on the lower with FULL weight, tap pin with hammer" tight. I have one, a CMT upper on a RRA lower, that I have to smack over my knee to get apart. I have two Stag and one Bushmaster lower, and those same uppers fit on them perfectly. Having said all that, I LOVE CMMG, and will buy more from them, but will be going with lowers "other than RRA" from now on. |
If those RRA lowers are older ones, those were known for being pretty tight. |
