This is a Crosman CO2 valve that's converted for use with bulk-fill and tank-block conversions, it's shipped assembled and ready to install. It has a Discovery Rifle valve-stem, valve-cap and our custom ultra-light stainless-steel valve-spring. The screw fits a T10 driver which is not included. Use our custom fill adapter item# 115688329141 to complete the bulk-fill conversion, that also allows you to connect a remote-coil and HPA tank regulated up to 1400 PSI. The 1.8K burst-disc on the regulator makes this safe, otherwise the bulk-fill tube assembly should never be pressurized to more than 1100 PSI. For tank-block conversion use our short-block item# 124985669073 or long-block item# 122399559046 depending on how large of a tank you decide to mount. The tank block can also be used to connect a remote coil if you want to keep the gun lighter and carry the tank in a pack. This valve is drilled and tapped to fit the included custom valve screw making it safe for CO2 and HPA tanks regulated up to 1400 PSI. This is not a PCP valve, it only has one valve mounting screw and is only safe to the stated pressures used as described.
