ok, so i have a King Arms Colt metal M4 AEG. I replaced the 368mm inner barrel with a 363 Madbull stainless steel 6.03 inner barrel and i installed a Madbull metal hop up ( with the single adjustment gear). Now, as I fire, I seem to get a side spin going and I can't maintain a tight group (and yes I know proper firing techniques). Can anyone make a suggestion to what I could correct in the weapon to improve my groupings ??
