TRIGGRCON 19 – GEN 12 from Genesis Arms – 12 GA Upper Receiver for AR10

The GEN-12 from Genesis Arms is a 12 ga upper receiver group for use with DPMS 308AR (gen1) lowers.

The short recoil operates as a delayed blowback with the barrel actually moving each time it is fired, like on a GLOCK. You can see the guide for the barrel in the end of the handguard. They are currently developing a standoff system for use as a breaching shotgun.

The reciprocating charging handle is on the right side of the receiver.

In addition to the upper, they provide a reliability package with beefed up springs for the bolt catch and magazine release.

Due to the operating system, the lower can be fitted with a folding stock.

The GEN 12 uses proprietary magazines. Five round versions are currently available, but they are working on a 10 rounder. The biggest issue was working out the curve shape for a smooth feed.

    Does the barrel unlock when you push back on it like a handgun taking it out of battery? Have they talked to any actual breachers? In use the barrel tends to get shoved pretty hard into the door jamb, sounds like that could be an issue with this system.

      I was just thinking this. I was trained to do a rocking or tapping motion. You rock in or tap the locking mechanism then slam it onto the door. Kinda like the first is a get ready. The second is a go. And if I slam the gun into the door will it still shoot or am I sol.

      It’s fairly simple actually. When it’s released by the company, you simply buy it, while still being in California.

      There are no laws that block you from getting parts.
