An NPAS developed for the MWS platform

The Crimson Waldo Dynamics MWS NPAS allows for energy adjustment of GBBRs using a compatible MWS nozzle . Its development with Bristol Based Airsoft focused particularly on compatibility with the numerous nozzle variants currently available for this platform.

The goal is to make the NPAS adjustment not limited to the original Tokyo Marui system. The part can therefore be used in several aftermarket nozzles, allowing for greater flexibility when preparing or upgrading a GBBR to the MWS standard.

Energy adjustment using a 1.5 mm Allen key

Once installed, adjustment is made with a 1.5 mm Allen key . After removing the GBBR bolt, the NPAS screw is directly accessible from the front of the nozzle.

The operation is simple: turning it clockwise decreases the energy, while turning it counterclockwise increases it. After winding, a chronograph reading allows you to measure the result and then gradually fine-tune the setting.

Adjust the settings to the conditions of use

On a GBBR, the energy output can vary depending on the temperature, gas or pressure used, the mass of the BBs, and the mechanical configuration of the replica. An adjustable NPAS allows direct adjustment of this parameter without systematically replacing other components.

This adjustability is particularly useful when the same replica is used throughout the year or with different configurations. Chronograph control remains the best way to accurately determine the energy output after each adjustment.

Compatible with Tokyo Marui and many aftermarket nozzles

The Crimson was developed and tested to work with a particularly wide selection of MWS nozzles . The list includes models from Tokyo Marui , Classic Army, Unicorn, Dynamic Precision, Double Eagle , Guns Modify, T8, and Prowin.

This compatibility allows the same adjustment principle to be maintained on an original configuration as well as on many setups using a replacement nozzle.

Specific compatibility with Salvo Precision

The Crimson NPAS is also compatible with certain Salvo Precision nozzles, with one important distinction: it must be a variant delivered without a factory-installed NPAS .

Salvo Precision nozzles that already come with their own original NPAS are not compatible with this version of the Crimson. This difference must therefore be taken into account when choosing the part.

Reinforced nylon polymer and Crimson identification

The valve is made from a reinforced nylon polymer . Waldo Dynamics uses the characteristic red color of its Crimson range, making the part very easy to identify among the components of a nozzle or on a workbench.

A simple but practical visual detail when maintaining multiple bolts or when different MWS configurations are present on the same workstation.

Installation and adjustment precautions

Installing the NPAS requires some technical knowledge and a few basic tools. Once mounted, however, adjustments are easily accessible from the front of the nozzle using a 1.5 mm Allen key.

When increasing the power, it is important not to unscrew the NPAS adjustment screw completely. After each adjustment, reassembly and a check with a chronograph will confirm the setting.
