HDP 50 GEN2 20 joules valve axle
Unlock maximum performance and stopping power from your .50 caliber marker with the high-performance Valve Axle for HDP 50 / TP 50 GEN2. Precision-machined specifically for second-generation (GEN2) platforms, this high-flow valve pin optimizes CO2 gas release during trigger actuation to achieve power levels up to 20 Joules.
Available now at Elite Shooter Supply, this tuning pin is CNC-milled from heavy-duty stainless steel to handle elevated chamber pressures without wear or deformation. By expanding the gas delivery geometry compared to stock restrictive pins, it allows a significantly larger volume of CO2 to pass into the chamber per shot—delivering immediate gains in muzzle velocity and downrange target impact.
Designed as a direct drop-in replacement for the factory valve pin inside the HDP 50 GEN2 / TP 50 GEN2 pressure chamber, this upgrade is essential for users seeking maximum target penetration, flatter trajectories, and consistent high-energy output.
