The WE-Tech Hi-Capa loading nozzle offers enhanced durability, improved gas efficiency, and better air sealing, which leads to more consistent and powerful performance. Enhanced Durability • Stronger construction: Many WE-Tech and other aftermarket nozzles are made from CNC aluminum, making them more resistant to breaking or fatiguing than stock polymer parts. • Better internal components: Upgraded parts included in many kits, such as enhanced return springs and high-flow valves, are built to withstand more stress from rapid firing and provide greater longevity. Improved Performance and Efficiency • Better air seal: Upgraded nozzles can provide a better air seal between the nozzle and the magazine valve, leading to more consistent muzzle velocity and a slight increase in power. • Increased gas efficiency: A better air seal and a high-flow valve can lead to more efficient gas consumption. • Faster cycle speed: An upgraded nozzle return spring can help the nozzle return to its firing position more quickly, leading to a slight increase in the pistol's cycle speed.
