Keeping the bore of you air rifle clean is assential for maintaining accuracy.
VFG felts are precision made to clean the inside of the bore of your rifle. Simply place a VFG in the bore with a pellet behind it and shoot the rifle. If the rifle has not been cleaned for along time, shoot 2 or 3 VFG’s.
Applying a littel gun oil to the VFG will greatly increase the cleaning power.
