Hybrid High Caliber Weapons (self.general)

I'm interested in helping research towards making higher-caliber weapons possible with fully DIY components. I'm still not that well versed in weapon design and I know many people here have more experience with converting components so the main thing I'd like to know is what limitations need to be overcome?

I have an idea for the ECM taper that may work but it's yet to be tested. The other complexity is the bolt carrier group and the locking mechanism but I think that can be made with guides. The other consideration is the gas system, a section could be attached to the gas port without welding with a clamp but then I'm not sure if direct impingement or a piston system is the way to go.

Any help is appreciated.

I would suspect the right way to work our way towards a fully DIY intermediate caliber design is to handle one part at a time. So start with a design that only DIYs the barrel, or the bolt, etc., then progressively step towards turning more parts from commercial to DIY.

I'd be curious to hear more about your ECM taper idea. What can you share about that?

An update - I've created early designs with full theoretical functionality, including a short stroke system and a locking system. I need to refine many aspects and then fdm test parts as placeholders for the metal to stress the mechanical elements function.
