Leaking and not cocking right

[paintballrgb]

My classic automag is reallt messed up. I have been shooting it on full co2 tanks and it doesnt want to cock back sometimes. it doesnt seem to get pressure to the cocker and you have no trigger pull. Then it starts to hiss and leak out the barrel. If anyone knows what to do or think they know what to do any advice is needed and wanted. Thanks in advance. And if it needs to be repaired how much do you think it would cost?

It sounds like the first thing you should try is replacing the reg. seat. This is a small whiteish disc about 1/4 inch thick that you'll see if you unscrew the two halves of the valve. You can get some of these reg. seats with an AIR valve parts kit. YOu can buy these kits for under $20 at most on-line stores or at your local paintball pro-shop.

You should also look into making sure that you aren't getting liquid CO2 into your gun. Liquid CO2 will put a lot of stress on your internal o-rings etc and will reduce their lifetime.

might just have to change the power tube spacer.
a kit is like 20 bucks i think.
