Here's my CMMG Radial Delayed Blowback 9MM Frankenbuild.
Here's my CMMG Radial Delayed Blowback 9MM Frankenbuild. It's a 9mm PCC with no gas system.
It's some spare parts, some new parts, and a CMMG Radial Delayed Blowback 9MM barrel and bolt. It's SOFT shooting. I'm still working on it. The Glock mags still sit too high. I know I have to file down the mag catch, but in the mean time, I just opened up the notch on the mag. I also removed the ejector since the RDB bolt has one like an AR15. Here's my parts list CMMG Radial Delayed Blowback 9MM barrel and bolt Aero XL upper Aero EPC lower Juggernaut Tactical Cal-stupid grip Gunshow handguard Rifle buffer tube Carbine spring and buffer ALG Advanced Combat Trigger (ACT) Lead Star stock EBay $20 muzzle break The bolt still drags over the mag, and my brass is scratched. It's a work in progress. Last edited by ysr_racer; 08-10-2022 at 9:20 PM.. |

What is the weight of your buffer? ALG triggers work fine in AR9’s?

The RDB Radial Delayed Blowback bolt carrier is the same size as an ar15 bolt carrier, so any trigger works. Most PCCs use a proprietary bolt carrier so they sometimes need a taller hammer to reset. That being said, my ALG trigger blows. It's at 5 pounds which is fine, but it's got a TON of creep and mush in it. |

Only a 3oz buffer? Is there extra weights in the BCG? That is an Interesting rifle.

Cool.. if sbr ever becomes attainable in CA, I would be all over something like this.
The concept of the delayed blowback is cool and essentially inverts the operation of the "locking lugs" and bcg cam action for pistol caliber |
