ACTION CLEANING
Clean all components of the action including the bolt assembly and bolt action slide to
remove accumulated residue. An evaporating solvent should be used. Action parts will
remain cleaner longer if lubrication is used sparingly.
RECEIVER CLEANING
Clean the inside of receiver with a rag or soft brush, giving special attention to the tracks
which guide the bolt and slide. Place a few drops of light oil in these tracks when clean.
Care should be taken when cleaning the exterior surfaces of the receiver to prevent
cosmetic damage. Never use a brush with metal bristles, as this could remove the
protective coating on the receiver.
TRIGGER HOUSING CLEANING
Brush loose residue from trigger housing with a soft bristle brush. Never use a
brush with metal bristles, as this could remove the protective coating on the trigger
housing.
Never pull the trigger while the trigger housing is removed from the
receiver, as damage to the trigger housing or personal injury may result.
GAS SYSTEM CLEANING
The gas system includes the magazine tube, gas piston, piston ring, seal, and the
gas action return spring (See exploded view). These parts should be
thoroughly cleaned using solvent. A stiff brass bristle brush is useful for removing
stubborn deposits.
Apply a light coat of gun oil to all metal parts and then wipe thoroughly with a dry
cloth. Excess oil will accelerate the build up of carbon residue in the gas system
and may have a negative effect on the shotguns performance.
