Alright, I've having strange velocity problems with my MR3. It's dropping off at about 30 or 40 feet. I though it was my spring so I bought a spring kit but it didn't help. I put the heaviest spring in there and now it's not even putting enough pressure behind the ball to push it out of the barrel sometimes. I tried all the springs and got similar results. My tank is full and I tore down my gun and made sure everything was tightened up. Any idea what's wrong here with the air flow or something?
