VFC M4 V3 BCG with NPAS is a replacement and upgrade Bolt Carrier Group designed for compatible VFC M4 V3 GBB airsoft rifles.

Featuring an integrated NPAS (Negative Pressure Air System), this BCG allows the user to adjust the amount of gas directed toward the BB versus the blowback action. This provides greater flexibility when tuning the replica to suit different BB weights, gas types, and field requirements.
