DISCO is not dead!!!!
I decided to get into PCP recently so I rounded up some parts, ordered a Magnum Airpower valve, Discovery tube and fill valve. It is in a Crosman 160 stock modified for Disco trigger. I have not done much testing, but shoots the 10 shots I tested around 1000 fps with 14.3 grain pellets 2000psi fill. This valve opens so easy I used a much weaker hammer spring than a disco one for easy cocking. Going to do some tuning later for shot count and fill pressure. It has stronger valve retention screws so I plan to go about 2200psi.
What kind of energy is this rifle producing? I have looked on their website and what they had posted was some extreme power levels out of such a small rifle, pretty awesome!
