I am going to get either the KWA CQR Mod 1 or Mod 2. I would prefer the Mod 2(shorter barrel) but I want the most range and accuracy possible. I was wondering if a longer barrel makes an AIRSOFT GUN more accurate or makes it shoot farther. I've done some research and the results were very mixed. If you know the answer, give evidence. I don't want "It makes it shoot farther because that's what happens in Call of Duty".
