    Looking at 14.5" uppers with a 1:7 twist and was interested if any thoughts on CMMG complete units.

    The first batch I bought were fine but on the last problem guns the customer service sucks.

    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 a 14.5 midlength from CMMG that has been great so far, 250rds.

    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".

    :dunno: 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.
