  1. Great job explaining gentlemen. We also went with a CMMG barrel and bolt. I ordered a complete upper. All you need is their bolt and barrel. I went with the Aero EPC lower and had to remove the ejector as it was not allowing up to close the upper. I don't believe you will have this issue if you go with M4E1. However it is a pain to put the Glock mags in and I most likely will replace the Aero lower (EPC) with the M4E1. I did go with Kynshot hydraulic buffer and Vltor extended buffer tube and Tubbs springs. The gun shoots so smooth. It's like shooting a 22. I have a couple hundred rounds trough it and it has yet to fail to fire.

  2. You have to use a CMMG radial delayed blowback barrel with their bolt. The barrel has the complementary cuts to the locking lugs on the bolt. That’s what allows for radial delay.
    I’m in complete agreement with you in regards to 9 mm PCC for home defense.
    I’m not wild about using a 5.56 mag that’s been retrofitted for 9mm, not unless it has an unmistakable visual and tactile differentiation from standard mags.
    However, I’d still rather have a dedicated 9mm mag, as I could fit more of them on a belt/chest rig/carrier.
