Hi, I have the RWS Scimitar pneumatic air rifle built in Sweden by FX I think (but before FX was formed) with the pistol grip cocking. My question is does anyone know how to seperate the stock/pistol grip from the action? It is an amazingly accurate rifle but is prone to leaking from the pressure guage and I'm sure it is a job I could do myself if only I could seperate the action. Many thanks guys and gals.
