Piston. These pistons come equipped with Belleville Shim Stack, designed for precision and ease of use. This innovative component allows you to adjust the output pressure of your regulator quickly and efficiently without needing to purchase an entirely new regulator unit. Simply pull out the entire shim stack unit and drop it into your regulator for seamless performance.The shim stack wraps around a robust brass piston equipped with all necessary O-rings, ensuring a leak-free experience. This piston stack is also an excellent solution for those dealing with a worn-out piston system that no longer provides consistent output pressure.Features:Lower Pressure Output:This piston shim stack is preset to make the regulator output pressure 250-300psi.Belleville Shim Stack:Belleville Shims (or disc springs) can provide a significant amount of force in a compact space. This compactness allows for a more streamlined and lightweight design compared to traditional coil springs.Quick and Efficient Swap:The entire shim stack unit can be quickly pulled out and replaced.Brass Piston:Durable construction with necessary O-rings for leak-free performance.Consistent Output Pressure:Ideal for replacing worn-out piston systems to restore regulator performance.Compatibility:Specifically designed for HK Army Performance Series Regulators.Caution:Ensure the air system is completely degassed before making any updates to the regulator to avoid injury or damage.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Upgrade your HK Army Performance Series Regulator with the LP3 (Low Pressure 300psi).
