Reinforced nozzle and CNC valve flap set for Hi-Capa
Planning a performance upgrade for your gas-powered Hi-Capa GBB pistol? Need a durable, long-lasting nozzle with a CNC-machined valve flap (Nozzle Valve)? Want to achieve smoother and more reliable cycling of your pistol? Then this is the ideal foundation for your upgrade build. This set from CTM TAC combines a reinforced nozzle with an adjustable CNC NPAS valve flap, which significantly boosts performance and reliability of the Hi-Capa gas system. The reinforced nozzle is made from injection-molded polymer with fiberglass reinforcement, offering excellent impact resistance and greatly extended lifespan. The CNC-machined 6061 aluminum valve flap provides quick NPAS power adjustment and improves gas efficiency thanks to its high durability and precision fit. Included is a softer bronze nozzle spring optimized for Green Gas, ensuring smoother cycling and more consistent performance. We also recommend installing the included Superalloy nozzle pin, which has a much higher hardness (68 HRC) compared to the stock part (28–32 HRC).
