You know the scenario: you’ve just perfectly tuned your air rifle, and then you accidentally give your hammer wheel a turn by rubbing it against your jacket. All the effort, gone!

This protective cap can be easily mounted onto the FX DRS Tactical using the included screw.
It prevents you, your clothing, or your rifle bag/case from accidentally turning the adjustment wheel.

Note: The very first version of the FX DRS Tactical does not have an external wheel.
In that case, this cap is not needed.
