Short stroke gas pistons; I was really pumped for that G36 model in 5.56 that I saw days before r/fosscad was taken down. We’re all so used to using DI in our builds but there’s so many advantages and interesting changes to design to consider with ss piston, like reducing receiving fouling and improving reliability for the former vs reducing bolt tilt and ensuring a path for the piston in the latter.
