Trifluted hammer + co2= low fps?
I was going to play stock class Sunday but I found a problem.
Using co2 I was maxing out at 160 fps, however I would get 260+ when using hpa.
So I am running a phantom with : back bottle valve, trifluted hammer, red spring, ported tpc (could put in oring but didn't), and a Lapco .681 barrel. I'm stumped on what is going on
