    Agreed. I think a dedicated lower is the best option, so much that I will be looking for another Black Friday deal on another QC10 lower for a dedicated PCC, already built the upper. This current one was my first ground up build and either I got really lucky or I just did enough research prior to ordering parts. Build the 9, it is the most fun piece I have. Everyone that tries it turns around with a huge smile after the first shot.

    I have enjoyed shooting mine, and have successfully run full 30 round mags through it without a malfunction. It's just a bit frustrating when it refuses to work.

    And the 147s jam up my Sub 2000. Maybe it's best to stick to the round nose loads on 9mm carbines.
    It just depends on the upper. My PSA and Faxon barreled uppers shoot my flat nosed 147 gr reloads just fine. I did have to increase seating depth a bit, then it was 100%.
    Yes, 9mm ARs can be a bit finicky compared to 223 until you get it sorted out. My tips: 1. If you use a drop-in trigger, get one made expressly for the AR9. Otherwise you can experience doubles and out of battery firing. Ask me how I know. The CMC 9mm drop-in is great.
    2. Increase buffer weight to about 7 or 8 oz with the extended buffer length made for 9mm ARs.

    With some tinkering, there is nothing more fun to shoot.

    Before I had to Californicate mine I had what I would call the normal 9mm build issues. On an individual basis making the Colt Style ASC mags work, was the most challenging, but I worked that out and now the thing runs reliably. I'm using a CMMG upper and a RRA 9mm Magwell Conversion Block. As said above everyone that shoots loves it.
