From what I can gather you could put a hole some place along the gas tube to let pressure off, like with a piston? Maybe I'm an idiot but this seems like a much more simple way to take much fouling out the reciever than adding springs, rods, and pistons. If I'm totally off-base then please correct me, but this seems like a much cheaper and simpler fix, As always thanks for the feedback guys!
