The .50 BMG behemoth has come a long way from the last firing prototypes and is now in a honest to goodness stamped steel receiver.
However, this is the “break shit” phase the development cycle where live fire is going to look for design weakness and where tweaks need to be made moving forward. The receiver is ugly and basically just a placeholder, the trunnions were altered to fit instead of stamping the receiver around the trunnion design, and the gas system is a best guess.
Welcome to arms design.
I am looking forward to his video on the run running and tracking the failure points for the next iteration. Making the AK run .50BMG is a monumentally cool project in my opinion.
Keep on keeping on Brandon.
