I have inquired to ask If i can go ahead and pay for it, And have NOT gotten a response. The nerve of some people!!
 I needed this upper quick and mailed my MO Express mail. Seeng that My upper would not make it in time for the weekend class, Im taking, CMMG took it upon themselves to ship it 2nd day air. Its here and the Morning Exercise / shooting class has gone perfect so far. 600 rounds gone and not a single failure out of a bran new upper, THATS WHAT IM TALKNG ABOUT.!!!!!!  BTW CMMG, Lot of the guys are Impressed with this build , Better get ready for Monday's orders!!!!! Ok Ok Ok already here are some pics, sans TA31 and LaRue <ount and the Troy BUIS (on order) (I borrowed my Brother In lawas camera, just for you all.. )   As for the Upgrade, I really dont want to say just exactly what it was with out permission. CMMG Upper Complete with MI Free Float rail. "F" Marked front site base. Bushy Lower CAA Collapsible 6 pos. Stock (the new Funk!) TD furniture. Coyote TA31F and LaRue 4DOS mount (not pictured) Troy BUIS (on Order) chuck |

Yeah, CMMG is top notch. I've got one of their uppers and love it. They'll be getting more business from me, no doubt about it.

CMMG is a top-notch organization. I have a M4 clone from them, and I REALLY appreciated the opportunity to customize the order so I didn't have to "repurchase" pieces afterwards!

Their barrels are tested, but I don't know if their current bolts are...(my older bolt isn't)

Do they HPT test before the MP test? If they don't HPT test prior to MP testing then the MP testing is worthless. |

Do they use milspec receiver extensions with their telestocks? Dremel feed ramps? What other companies offer 14.7 inch barrels/uppers? TIA.

The M4 feedramps on mine look incredibly professionally done. Definitely not hackjobs like some other manufacturers. Not sure about the receiver extension since my lower is a Stag, but the upper is CMMG. |

I've got a pistol upper on order from CMMG, and it's been delayed a bit because they didn't have the rail system I wanted. (samson carbine rail). It's been a week now, so hopefully they'll get it built and shipped out to me soon. I have a feeling that they've become more popular lately, and having a little difficulty keeping up. (really, I'm just anxious to get my upper) h.gif
I talked with them on the phone and they were very nice. They also seem pretty flexibly when it comes to special requests. When I get my upper, I'll be able to make my final verdict. But, so far dealing with them has been pleasant. |

Good question. Does anyone know if their barrel extensions are stamped M4? |

Ramps are anodized(we also offer extended polished) In the next 30 days we will have the option of mil-spec diameter tubes(they are just finishing up). We will continue to offer the commercial diameter as well. |

+1 for CMMG's customer service. Don't be afraid to ask questions. I picked up a 9mm carbine from them and the fit and finish is great, John is a pleasure to work with. Think I'll have to call them soon and order a MI set of hand gaurds. Either that or a FF from MI.

Ok the pics are posted above in ordginal post. I cant really say what the "Upgrade" was but lets just say Im happy as hell with it and I love the Continuous rail on top with the MI FF tube.
I have a Troy on order for the BUIS and The TA31F in a Larue is in the safe. My Bolt is Not marked MP tested Im not sure about the HP testing, I thought the barrel is MP tested though, according to the web site. Even if not, I dont think its that crutial considering the quality. I dont think Bushy, Armalite, or most others MP test, do they? Ive never seen any of my rifles marked that way? Now I just need to get to the range. chuck |

The Military requires HPT testing before MP testing. If you don't HPT the bolt and barrel then you are not stressing them in order to find cracks (which is what MP testing does). To the best of my knowledge, only Colt and BCM do this. Is it important to the everday plinker? Most likely not. Is it important to the Military/LE community? You betcha! |

Miltary maybe , But I dont know about LE for most officers and applications, How many Bushy, RRA, and Armalite rifles do you see in LE circles? A SHIT LOAD!!! Im very confident this rifle and barel, will hold up to any abuse I throw at it. BTW, Im not a Plinker, Ill be running this with a SHIT load of M855 ball and MK262, we'll see, but Im not worried.

Depends on the LE group. I would bet you will find more Colt's than any other company. The spec is there for a reason. I guess I look at this way. Company A has an upper for $400. Company B has an upper for $400. Company A follows all the military guidlines and reqs. Company B follows some of them. They are priced the same, but one company jumps through a lot more hoops to provide a better product. |

The Barrels are MPC tested as per web site and marking on my barrel. The Bolt is not.
Are you talking more about the bolt or barrel.? Barrel is marked under handguard. CMMG MPC 556 NATO 1/7 chuck |

Mag particle will still find discontinuities even if the barrel is not HP tested. Correct...HPT COULD help reveal additional discontinuities. Keep in mind, mag particle testing does not reveal internal discontinuities. Nothing is 100%. I myself would put more faith in knowing the proper heat treat was acheived. That may be one of the functions of HPT. I do not know. Non Destructive Testing is my profession. |

Talking both as they BOTH need to be proof loaded before they are MP tested. |

Yes it can, but you want to stress the barrel first to verify that it can take it. The question to ask is what is the acceptance criteria of an MP test? Does CMMG reject a barrel if it has a small fracture in it? |

Bravo Company Manufacturing. Bravo Company is a site sponsor and came out with their own barrels and uppers. Paul from Bravo Company wanted to offer a barrel that meets military specs without breaking our checking accounts. Several dealers on the board sell BCM uppers but depending on where you are in VA you should check out G&R Tactical. They are located in the Hampton Roads area. I have a BCM upper and an older CMMG upper. I understand why everyone wants the HPT-MPI but is it necessary for most people? I'm willing to bet it's not. IMO it's more a 'want' than a 'need' for most people but YMMV. My CMMG upper has several training classes and 8500 rounds through it without a hiccup and so far my BCM upper (750 rounds) has been perfect. I wouldn't hesitate to recommend either one. |

People would be shocked to learn that most acceptance criteria allow discontinuities. They are not defect free. Size is usually the determining factor. Certan types of defect are rejected regardless of size. Logically cracks, seams, hot tears, bursts etc....depending if you are inspecting castings, forgings, weldments etc.. Concerning barrels, I do not know what the criteria is, Could be a Class I Grade A I do not know. Actually, I have x-rayed many, many AR15 triggers and bolt catches. We do it for "in-process control" meaning that while they are being made you sample a lot and inspect. Defect free....not! I have noticed that over the years that customer auditors from companies such as Boeing, Honeywell, Lockheed and what is called NADCAP (national aerospace and defense contractors accredidation program) have put much more focus on heat treating. If heat treat was improper the NDT results are meaningless. It would be interesting if someone on this site who has actually done mag on barrels and bolts could chime in and let us know what the procedure and criteria is. I am assuming it is wet mag that is being done.....anyone?. |

Actually, the vendors on this site whom are outsourcing barrels etc for mag inspection should be specifying the acceptance criteria the test lab is to use. It is not the job of the test lab and inspectors to determine what is acceptable. It is the customer requesting that the work be done.
Possibly CMMG could help us out here?? |

Yeah, I was going to chime in about aircraft engines, which you kind of already did. Parts on these engines have an acceptable allowance for cracks, chips, etc before replacement is required. Aircraft engines for God sake!!! Like the ones our military uses in their multi-million dollar planes. So why are we so worried about these bolts? How many of you have actually busted a bolt? And for the few of you that have, I'll bet the round count was real high. Doesn't Colt say to replace the bolt every 5,000 rounds? Honestly, I don't think it's that big an issue whether you're military, LE, or a plinker. You guys on ARFcom here nitpick too much  .

+1, on Customer service, they shipped the wrong product to me, after I called about it they sent out the correct product same day and threw in a small goodie for the slip up. Great company. Being a Missourian, I am proud to have an AR "Made in MO".
Thanx CMMG. Heres the AR I built on their lower.

This is correct. Having talked with Paul at BCM, he rejects any & every barrel that has a stress fracture in it. |
