Frequently asked questions

Are GBB parts universally compatible?

Not always. Many parts are platform-specific or brand-specific. So check whether a part is suitable for your type of GBB.

What exactly does an NPAS system do?

An NPAS system regulates the amount of gas that is allowed through, allowing you to adjust the FPS of your replica to the field and conditions.

Do I need to replace my nozzles and valves regularly?

Yes, especially with intensive use. Worn nozzles and valves can lead to inconsistency, gas leakage and loss of performance.

Are cosmetic upgrades purely for appearance or are they also functional?

Many cosmetic upgrades not only improve the appearance but also the fit or stability, depending on the design.
