Well PRO MCX XM5/XM7 Loading Nozzle & NPAS Set (MWS Compatible - WG10 1.5J nozzle)
Fine-tune your muzzle velocity and ensure consistent gas flow with the Well PRO MCX XM5/XM7 Loading Nozzle & NPAS Set (MWS Compatible - WG10 1.5J nozzle). Designed specifically for the Well PRO MCX Spear (WG68 / WG10) series and Tokyo Marui MWS-pattern gas blowback bolt carrier groups, this complete replacement nozzle assembly combines high-durability polymer construction with an integrated adjustable NPAS valve.
Pre-configured to support up to 1.5 Joules, the built-in Negative Pressure Air System allows you to adjust your FPS output easily to comply with strict site limits or optimize performance across changing seasonal temperatures.
Maintaining consistent gas output and staying within skirmish site limits are crucial for any gas blowback operator. The Well PRO MCX XM5/XM7 Loading Nozzle & NPAS Set (WG10 1.5J nozzle) provides a heavy-duty, drop-in replacement internal nozzle solution engineered specifically for the Well PRO MCX Spear / XM7 series and TM MWS-compatible gas bolt carrier assemblies.
Integrated Adjustable NPAS Valve & 1.5J Output Tuning
The defining advantage of this nozzle assembly is its factory-integrated NPAS (Negative Pressure Air System) valve. Rather than being locked to a fixed factory output that fluctuates with ambient weather or green gas pressures, this nozzle allows technicians and players to fine-tune the internal gas ratio redirected between projectile velocity down the inner barrel and recoil impulse driving the bolt carrier. Rated up to 1.5 Joules (approx. 400 FPS on 0.20g BBs), the valve can be dialed down for strict CQB limits (under 1.14J / 350 FPS) or adjusted upward for long-range outdoor DMR configurations.
Durable Reinforced Polymer Construction & Cold-Weather Resilience
Manufactured from high-density, impact-resistant engineered polymer composite, the nozzle body is built to withstand repeated, high-speed impact cycles against the hop-up chamber and barrel extension. Unlike brittle factory plastics that can crack under high-pressure propellants or prolonged rapid firing strings, this polymer maintains flexibility and mechanical strength even in colder skirmish environments. Precision-molded gas intake ramps and high-grade internal O-ring seals ensure a tight, low-friction seal against the magazine gas route bucking, minimizing gas loss and preventing cycling drops.
Practical Applications & Real-World Use Cases
-
Skirmish Site FPS Compliance: Easily adjust and dial in your muzzle energy before chrono checks to comply with indoor CQB or outdoor woodland site power limits.
-
All-Season Gas Balancing: Rebalance your gas distribution between winter and summer conditions to prevent over-gassing on hot days and sluggish bolt cycling in winter.
-
Complete Drop-In Overhaul: Serves as a direct replacement for cracked, worn, or deformed factory nozzles to restore consistent velocity and smooth BB feeding.
Compatibility
Engineered for the Well PRO MCX Spear / XM5 / XM7 series (WG68 / WG10) and fully compatible with standard Tokyo Marui MWS (ZET System) spec gas blowback bolt carrier groups. Supplied complete with the internal NPAS flute valve, return spring, and piston cup seal.

Stating what the problem is, if we can resolve the problem via phone or email great if not then they will advise how to send it back and what details we require.
The gun will be sprayed 51% in a bright/primary color (we do only blue, green and red currently). The process of two toning currently runs at 2 working days depending on Drying Time, which is effected by Ambient Temperature and Weather. and currently no express delivery is available for this even if you select it at checkout.
