FX new regulator rod – upgraded brass version including seating surfaces for the FX Crown & Crown MK2 air rifle.
Includes o-ring D26 (19109).
Please note: The total length of this rod is 16mm. For very very early mk1 crowns the length is a shorter 14mm. Please contact us first if you require this shorter part.

Now newest (second version) of the brass piston with no hole in side and a flusher sealing face.

Damage to the polymer face of this part is often a cause for regulator creep issues.
