  1. This one is the best BCG for 9mm built

    Posted by Luis Cajiga on 25th Aug 2017

    This product works great with any AR-9 lower. I have tries other brands but with dedicated lowers that have a bullet feed ramp they don't fit well. CMMG BCG works flawlessly.

    Most important, 9mmAR as a company id 5 Stars also. They stand behind their products and always tried to please you when you need them the more, when returning items. These people gives you high more than expected service. Highly recommended.


  2. Fantastic product and service

    Posted by Zee33 on 10th Mar 2017

    The cmmg bolt is well made and very solid. I'm using it with an 8oz. extended buffer. Bolt runs nice in my real upper. I penetrated it with Ballistol. Still in the process of my build so not sure how it cycles yet.

    Shipping from 9mmar.com was fast and order was processed fast too. I will definitely buy from 9mmar.com again


  3. works flawlessly

    Posted by Bobby on 20th Feb 2017

    Used in conjunction with a Hahn dedicated block and metalform mags


  4. Wicked reliable

    Posted by Unknown on 3rd Jan 2017

    So far I've purchased a few of these and in combination with their brand barrels have been rock solid. One FTF but I blame that on my buddy riding the charging handle.


  5. Works perfect!

    Posted by Marv on 25th Feb 2016

    Built doaen of .556 ARs. First AR 9mm build. Used CMMG barrel, this bolt assembly and the CMMG heavy buffer. Dont use the heavy buffer without a spacer. They say you won't break the bolt catch and I didnt but I bent it. Get a spacer!


  6. Works Flawlessly

    Posted by DTD on 11th May 2015

    This bolt functions very well and fits into my Yankee Hill upper perfectly. Would buy again.


  7. works as advertised

    Posted by Unknown on 24th Apr 2015

    Third 9mm build using this bolt, works as advertised, not fancy, justs does the job, rear mass is removable for use with JP captured spring. Other reviewer says milling required for use with Glock mags, this is NOT correct, all three of my builds are Glock mag specific and I run them as reviewed without any further mods or problems. This is the 9 mm bolt to buy


  8. Smooth operation

    Posted by Unknown on 7th Apr 2015

    Very smooth operation, its paired with a Wolff xp spring and spikes heavy buffer. Works flawlessly


  9. fit and finish issues ........

    Posted by andrew on 6th Mar 2015

    overall - works real good. But finish is not so great. CMMG needs to do some deburring before finishing out - so their customers don't have to.
    after 20 rounds, I found much scoring in the upper. I should have inspected for burrs to start with.
    Nothng a needle file wouldn't take care of. Would buy again.


  10. Looks good so far

    Posted by dino on 18th Feb 2015

    This is my first 9mm build. The bolt looked awesome and fit the VLTOR upper great. The service is what really stood out. I had my parts before I ever checked tracking.
