CO2 VALVE STEM for 2240, 2250, 2260, 2300KT & 2400KT


This item is out of stock

 This valve-stem is original to 1740, 2240, 2250, 2260, 2260MB, 2300KT and 2400KT models. The sharp pin pierces a 12-gram CO2 cartridge on the first shot, which should be dry-fired (unloaded, with no projectile) in a safe direction. It fits 2300T and 2300S models but isn't the correct part for them, those have a stem with a longer brass spring-guide that limits how far they can open. The pin on this stem is the same diameter (.154") as the Discovery/Challenger stem which is often used to convert a 12-gram CO2 model to bulk-fill, HPA or PCP.
