Recently bought a first gen Tippmann SL 68, aired it up and it fired but I could hear a small leak coming from the rear. Disassembled it and replaced the two o-rings. Reassembled and had a leak down the barrel. Pushed the valve/valve seat back further and re installed the set screws, has no leaks but can hear air escaping when I open the breach, and occasionally fires multiple shots when pumping back. Thoughts?

How does the cup seal look? Leak down the barrel is typically that. -
Sounds like a cup seal.
