FS Guerrilla G3/P3 Regulator Pressure Kit

FS regulator spring kit.

Item was shipped quickly from the date of purchase, which was great. This was purchased to allow me to lower the operating pressure of my FS Hero reg. There was no original FS packaging with the received kit, which would confirm the springs operating range and any installation instructions. Instead, the items (spring and shims were in sealed "baggies" and a FS product card only.

This product is fantastic. It’s certainly the lowest profile tank I’ve found on the market. It performs perfectly on my Sig Sauer MPX as part of the HPA conversion.

Regulator Kit

Very helpful staff, fast service, works perfectly.
