Well PRO MCX Rattler/Spear Loading Nozzle & NPAS Set (WG10)
Product Overview
The Well PRO MCX Rattler/Spear Loading Nozzle & NPAS Set (MWS Compatible - WG10) is a premium, high-utility gas blowback (GBB) internal upgrade component engineered specifically for the Well PRO XM5/XM7 (MCX Spear) and Rattler series, as well as platforms utilizing the Tokyo Marui MWS ZET system architecture. This complete nozzle assembly introduces an integrated Negative Pressure Adjustment System (NPAS), which allows operators to dynamically adjust muzzle velocity (FPS/Joules) with a simple adjustment tool to comply with varying field regulations and ambient temperatures. Well PRO circumvents the brittle fracturing and structural fatigue typical of factory-standard nozzles by molding the WG10 from a high-density, fiber-reinforced impact polymer capable of absorbing continuous high-pressure gas cycling. The compression group is factory-fitted with premium, low-temperature resistant O-rings and a reinforced internal valve, ensuring an absolute air seal and exceptional shot-to-shot consistency. Whether tailoring a rifle for indoor CQB limits or maximum outdoor range, this drop-in kit provides the fine-tuned control needed for competitive gas blowback platforms. For B2B trade stockists, custom build workshops, and dedicated airsoft retailers, this highly requested NPAS nozzle set offers a vital, high-margin performance upgrade that addresses a critical tuning need for end-users.
