Leakage help

XVR

This one has a lot of variables and there may not be anything wrong at all. I shot it, and it did fire well. It did. However, it did, occasionally, where the velocity adjuster is, leak a bit of air. Just a small hiss for a second or two, barely any loss of air. My can I used is old, a nine-ounce Co2 can from my first Gryphon, and it might be the problem. It was very cold out, and my tank is not yet anti-siphoned or remote lined. Any ideas?

TiPX

Ok, this one is most likely broken. Upon firing, the gas started flooding everywhere. I tried it multiple times, but to no avail. I also noticed the cartridges had only a teeny hole, not sure if normal or not. They were not Tippmann, they were Crossman, but seemed to fit fine. Suggestions?

Thank you!
