Replacement front block assembly for the Hatsan Factor air rifle.

Includes:
– Bottle adaptor
– Gauge block assembly including gauge
– Fill valve unit
– Firing valve unit including main valve, housing etc. This is set up with UK spec (sub 12fltlb) valve spring. If for high power replace this spring with your original.

This is sent to us from Hatsan as a salvaged unit and shows signs on the main valve of fitting to a rifle (see second photo). No other marks are visible.
