OK well, I currently have a JG SR16, otherwise known as M4 RIS. My fiance's echo 1 Scar-L, with a 9.6v has amazing ROF. Same with my Sig 556. When i put my 9.6v in my JG M4 is just horrible with ROF. Its goes shot......shot......shot.....shot, on automatic. So what can I do? I will look for a new m4 or is there anything i can do?
