Once I went with Endomags and CMMG radial delayed, I really haven’t looked back.  Until this week.

I have two SBR lowers collecting dust that I registered prior to the endomag / CMMG.  One is Glock magazine and the other is Colt magazine.  Any recommendations on what to build with them?   Should I just strip the receivers and pack them away?

I believe I have so many 9mm parts, that I probably have several complete uppers in there.  Is it worth it now that I have the CMMG FE and endomags?

I’d like to put a 9MM together myself but don’t know what to start with. There are dedicated 9MM lowers, that don’t need mag adapters ? I’ve built several AR rifles and pistols, 5.56 and 7.62x39 but 9MM is a different animal. Subscribed for info.

If I were building a straight blowback PCC AR a PSA DOE 9mm build would be my first choice.

Thanks.   That does look super cool.   I have an old school A3 metal stock somewhere, it came on an M16 I bought.

I have to double check what configuration the lower is in with ejection.
