Polarstar Gold Poppet for F2

The optional Gold valve expands the capabilities of the system even further by making it more flexible and adaptable when tuning for different rifle configurations.Replacing the Standard Red poppet in your F2™ with the Low Flow Gold poppet will shift the rifle’s velocity adjustment window down allowing the system to operate at a higher pressure while retaining a lower velocity.

This low flow poppet is beneficial in situations where a longer barreled rifle needs to achieve a lower velocity than can be reached within the normal operating pressure range of the F2™.

We have provided a comparison chart to show the output of the two different F2™ poppets over a range of pressures and BB weights using a 6.05x380mm barrel as a testing benchmark.
