Playing around with the tube SMG & the Aguila 12GA mini-shells...

That's absolutely dastardly. I love it. I have thought about a single stack mag fed mini shell shotgun for so long, MANY years. Or somehow converting a saiga 12 to minishell mags. The only thing you really need to worry about is rimlock of the shells. I would LOVE to see this released. It would keep me from designing a pump action mossberg receiver that's mini shell only length. I keep thinking it would be nice to have a super compact pump, but this looks like it would be blowback awesomeness.

    Thanks! :) Yeah, I like the mini's a lot. I use them almost exclusively in my tactical Moss. There's a tough rubber wedge you can insert that makes using the shells hassle free. I got the main idea from that South African version with the mag in the grip. This design is so much easier to alter, & rim lock is easy to avoid by careful loading... I've had some picky .22 banana mags that would lock up if the rims wheren't in perfect order.

    What's cool is that this is actually a very simple, proven design... 3D printing & all the metal from the hardware store. Modern Bill Holmes style. The only real drawback is that it's full auto, open bolt. That makes building one "a bit risky". I need to play around with it & see if I can find a close bolt semi for the action...

    Credit where it is due sir! Very cool stuff. I've got some of those OpSol adapters, gen 1 and 2 and their complementing follower, but I haven't had the time to test them out. I need to go and have some fun at the range. Life is just work-work-work these days. People seem to have good results with them.

    The neat thing about the shorty shells for me is reloading. After a couple reloads of conventional length 12 gauge the shells don't like to take a crimp anymore or are too thin/brittle from the heat exposure, so you just trim off the end and voila! Brand new shells with a primer pocket squeeze, and more reloads, just in a shorter format.

    I think I know what shotgun you are talking about, Is this the one? : https://modernfirearms.net/en/shotguns/south-africa-shotguns/mag-7-eng/

    You know I've always wanted to learn how to design man. I'm an ideas guy, but I need to try and get involved. I'd love to be able to make my own designs for my saiga 12 and other firearms since it's not a very developed area in the space, a few designs here and there. My idea for your design is to hunt down a double stack mossberg magazine, cut it open and study it's internal geometry and adapt it for the mini shell lengths, but I really like your single stack design as well. I hear you about the open bolt challenges, be careful testing with OOB my friend and stay safe. GOOD LUCK! It's awesome work.
