I am. I started having some feeding issues so I’ve backtracked a bit to diagnose it. I’ll probably have to redo the connection point between the tower and drum because something is slightly off enough to cause binding issues. Everything else is done, just need to fugure out that last bit. Magazines are tricky to get right. Drum mags even more so.

Thank you, I’m quite proud of these two.

To your question, I spent some time trying to crack the case myself, and in my own findings, the upper does not have enough room for the required amount of weight needed for reliable cycling at the higher rate of fire. If you could fit enough weight in the upper, theres still no easy way to keep the weight attached to bolt. Theres no hook or clipping point like the CMMG design has. Epoxy was an idea, but there’s no way it would hold for any length of time. The trip I designed worked, and I could get some 2-4 round bursts from that alone, but inconsistently. Adding weight was the big issue.

It has been done before, but not without heavy modification/fabrication to the bolt, and my goal was to create a drop-in design with minimal mods needed to the firearm itself. Unfortunately, that’s not possible, so I shelved the project. In my opinion, it is not worth it to go to such lengths, when you can build a CMMG kit for less money and and much less effort.

Reddit on some bullshit again. Glad you made it here bro. No more eggshells to walk on.
