FX Impact Power Block Valve Block Upgrade with 720 plenum.

This kit converts MK1, MK2 PP720 and earlier M3 rifles with 720 plenum but no power block to the power block version.

Comes serialised with a new serial number – this is important in some countries where airguns must be serialised – we specifically request them like this from FX, as as standard they come blank!

Uses existing valve rod etc, so only works is you already have a 720 power plenum on your rifle.  

If on FAC please contact us as we will need to get the block made up with your existing serial number.
