Hey I'm having a problem with my Mr2. i have no power, i have to arc the gun to get it to shoot twenty yards. I've tried moving the velocity spring, even all the way down I can't hit anything over twenty yards. I've tried just about everything, my only two guesses would be either i need a new velocity spring, or my electronics are going bad. I have a 16 in barrel, this problem has just accrued since i got my new barrel. I'm planning on getting a new spring kit and a low-blow bolt when I get a chance. Any ideas how to fix this?
