FX T-12 Whisper .22

Note-The regulator is shown backwards in most of the Monsoon pics I sent you.

The end with the nut should be closest to the receiver. It slips into the steel "standpipe" spacer.

The .177 Monsoon has a regulator. the .22 Monsoon and all Whisper's do not.

As far as I know, the .177 Monsoon is the only FX that uses a regulator.

The Whisper is very similar to the Monsoon and this shows pulling the valve apart.
