I am happy with my CMMG M4 LE upper on my newest build. I have about 500 rounds through it so far, 100 percent reliable and I have shot some sub 1 inch groups at 100 yards with a 3-9 scope. From my research they make outstanding quality products for the price. Its reliable and accurate, what more do you want?

I have seen a bunch of them. They are nothing special and over priced compared to others on the market now.

Yeah they work, it doesn't have DD, LMT or BCM printed on it but it gets the job done.
CMMG is military grade stuff, read their specs and you'll see that.
*certified 4150 chrome-moly vanadium steel
*5.56x45 NATO chamber
*1:7 twist
*Hard chrome lined chamber and bore
*M4 feed ramps
*11 degree recessed target crown
*F marked forged front sight base
*Parkerized Barrel including under the front sight base
*A2 Flash hider installed with Peel washer
*Forged A3 upper receivers are T marked and have extended feed ramp cuts *(M4 ramps)
They are now offering cold hammer forged barrels.

All advertising specs and no proof.
Barrels are said to be the worst in the industry.
Shoddy workmanship, poor CS.

As evidenced by this thread, their reputation for quality and customer service is spotty. Some people are pleased with them, many are not. I’ve spoken to the two brothers that own the company at local gun shows. They can certainly sling the BS. I would look elsewhere.

If you think the two sons sling the BS, you ought to talk to dad.
He tells so many whoppers it is hilarious.
"CMMG is used by the Special Forces, CMMG has the contract", was my favorite.

If it's your first AR, I'd avoid a 14.5".

 Where did you get that statement from? Before I bought my CMMG upper I talked to quite a few people who had them and they all seemed happy with them.
In fact I have not heard much negative about CMMG outside this forum, from what I understood they were a solid mid range AR company.

I have seen chamber issues and cant. Barrels are not always centric. Gas ports are all over the place dimensionally.
ADCO has said for a long time CMMG barrels are the worst in the industry.

Well do you think I should get rid of my CMMG upper and get a BCM or whatever? I've got two ARs ones a Stag 24 in barrel for varmint hunting and the CMMG M4 which I depend on for HD, serious use sort of stuff.

No. If yours works, great. Keep it, enjoy it, be happy. However, if you are looking to buy, there are many places that have better QC and CS.

I wanted to say I heard a rumor at a gun show...here in missouri, now you know about rumors being BS but a guy was telling me and my friend that some of the parts on CMMG uppers were actually made in china, now I dont know if that is true or not but seeing other complain about their workmanship I would steer clear.

Well I took my 3 CMMG uppers to LotharWalther locally and looked inside the chambers and barrels.. they sucked... Horrible machining and good thing we did not put the AAC supressor on them because the barrel was threaded off center on two of them, Chrom plating was uneven, the barrels are NOT GOOD.. now the FA lowers function perfectly with the newly built uppers so NOT all of their stuff is bad but the barrels are crap...and thats what you pay for in an upper.

Yeah well my "crappy CMMG barrel" shoots MOA groups, as good as some of my friends rifles that cost twice to three times as much.
Just because a few examples of CMMG products are bad does not mean the all are. Same ****ing deal with gen 4 Glocks. What do guys do when they have a problem with their new gun? Go online and rant about it. Suddenly the company makes the gun now sucks, the model of the gun now sucks, and the dealer they got the gun from sucks... and then idiots repost that crap all over the internet...

Breathe.....
I'm sure not all are bad. But the numerous ones you hear about, plus one of the biggest shops in the country says he sees A LOT of bad barrel....... Were there is smoke look for fires not petunias.
If yours is good, GOD bless ya.
