I have a Trilogy Sport Pump, and I'm getting a leak out of the barrel. It has all new internals, but leaks out the barrel when aired up. I bought a mad man spring kit too for it, so what else can i try?

did u cock the gun before u attached the tank?

Make sure it's cocked before you air it up.

If the hammer isn't resting on the sear, it'll be resting on the valve stem, which can leave it open, causing the leak out the barrel.

If it doesn't go away by cocking the marker, then you've probably got a bad cup seal.

Ill try that, but the cup seal is brand new. Also, I was wondering if there was a kit I could buy or what I could use for a valve spring. All I can find is a low pressure kit.
