Airgun enthusiasts, this PCP conversion kit takes your Crosman to the next level! If you have a 1377, 1322, 2240, 2250, or 2260, this kit transforms your CO2 or pump gun into a serious pre-charged pneumatic powerhouse. The valve handles up to 25 mPa working pressure, while the cylinder can go up to 30 mPa - though you'll want to keep your fills between 5-15 mPa for optimal spring performance. The high-pressure sealing means no leaks once you hit 3-4 MPa, and you can expect about 20-50 shots per fill depending on your specific setup. Installation is pretty straightforward - you mainly need to keep your original barrel, grip & trigger set, and push pin. The kit comes pre-tested, so you don't need to mess with the valve adjustments. One thing to note - there aren't instructions included, but if you're familiar with airgun modifications, you should be fine. The spare accessory package is for future maintenance, so just tuck that away for later. This conversion really changes the game in terms of consistency and power compared to standard CO2 operation. You'll notice smoother shooting and more consistent velocity shot to shot. Just remember to use proper high-pressure air sources for filling and always follow safety guidelines when working with modified airguns. If you're ready to step up your airgun game, this conversion kit delivers professional-level performance.
