NPAS GBBR for VFC / APFG / Maruyama / Marksman OPS-FACTORY

An NPAS developed by OPS Factory to adjust the power of many compatible GBBR platforms

The OPS-FACTORY GBBR VFC NPAS was developed and manufactured directly by our workshop to provide an adjustment solution for a wide range of GBBR replicas using VFC or compatible mechanisms.

Its design allows you to adjust the gas system’s operation to vary the replica’s power after installation. Adjustment is performed using a 1.5 mm Allen wrench, allowing the NPAS to be fine-tuned according to the desired configuration and field-specific limitations.

The part is manufactured from PA12 nylon using the MJF process, an additive manufacturing technology that enables the precise production of the shapes required for its integration. The NPAS comes with its own screw, providing all the components needed for installation and adjustment.

Developed for VFC’s GBBR platforms, this model also offers broad compatibility with several replicas produced by APFG, Maruyama, and Marksman.
