Description
Well PRO MCX XM5/XM7 Loading Nozzle and NPAS Set (MWS Compatible – WG10 1.5J Nozzle)
This is a loading nozzle and NPAS set from Well PRO for its MCX and XM5/XM7 style gas blowback rifles, listed as MWS compatible and as the 1.5J nozzle for the WG10. The nozzle is the part on the bolt carrier that chambers each BB and directs the gas that fires the shot and cycles the bolt, and NPAS stands for negative pressure adjustment system.
An NPAS nozzle includes an adjustable valve that controls how much gas reaches the BB. That lets a technician fine-tune the rifle’s power and gas efficiency without changing other parts, which is especially useful when setting a rifle up for a specific power level or BB weight.
How NPAS works
In a standard nozzle, the gas flow to the BB is fixed by the design. With NPAS, a small adjustable valve inside the nozzle meters the gas, so turning it with the correct tool raises or lowers the power. Adjustments should be made in small steps, with the rifle chronographed after each change.
Because the setting affects power, it should only be adjusted by someone who understands the rifle and has access to a chronograph. Always make sure the rifle is set within your site’s limits before play.
Fitting
Fitting a nozzle involves stripping the bolt carrier group. If you are not familiar with the process, have the part fitted by an experienced gas rifle technician. Remove the magazine and make sure the rifle is empty before you start.
After fitting, check that the bolt cycles smoothly and that the nozzle returns fully, then test-fire and chronograph the rifle before use in a game.

Compatibility
Listed for Well PRO MCX and XM5/XM7 style gas blowback rifles and as compatible with the MWS system. Nozzles are very specific to each rifle’s bolt carrier design and power configuration, so please check your rifle’s model and current set-up before ordering, and contact us if you are unsure.
Spare parts are often specific to one manufacturer, and sometimes to one production version, so please check your replica’s make and model, and compare this part with the one you are replacing, before ordering. If you are unsure, contact us with details of your replica and we will help.
Care and maintenance
Keep the nozzle and bolt carrier clean, and apply a thin film of silicone oil to the nozzle’s moving surfaces during servicing. Avoid petroleum-based lubricants, which can damage seals.
If you are not confident working on your replica, have the part fitted by an experienced technician. Keep small screws and springs in a tray while you work, and test the replica’s function carefully with no BBs or gas loaded before using it in a game.
Who is it for?
This set is for owners of Well PRO MCX and XM5/XM7 style gas rifles, and gas rifle technicians, who want an adjustable nozzle to fine-tune power and gas efficiency or to replace a worn nozzle.
Please note: Fitting and adjustment should be carried out by an experienced technician, and the rifle must be chronographed after any change.
