Ah ha! Got it! That makes more sense. Thanks for all the help fellas! I have one more inquiry. When I took my M4 in to get the BC 1 installed the smith installed it upside down. I asked and he said it's so the gases escape up to keep the muzzle down. It clearly states in the directions to have the emblem facing up so that's what I made him do. Does anybody have it installed upside down? If so do you notice any difference?
