FDust-guard for cylinder

Feinwerkbau dust-guard for cylinder An inexpensive end cap to push over the valve and screw threads of any Feinwerkbau CO2 cylinder or Feinwerkbau Air cylinder - it fits them both exactly the same. It fits the rifle and the pistol cylinders so one size fits all. This simple cap prevents damage to the screw thread and the valve ending and keep them both clear of dust and any other small debris. It is helpful when the screw threads have been coated with Feinwerkbau grease to prevent anything sticking to the greasy areas.
