MANUAL P 19
Note: Items 4 & 5 should be applicable only after ring.
4. Attach nylon wire-bristle bore-cleaning brush to cleaning rod and dip brush in
rearm-cleaning solution. Thoroughly scrub out barrel, passing the brush all
the way through before reversing the movement. If you try to change direction
with the brush in barrel, the brush can get stuck and cause damage to barrel.
5. Attach the larger chamber-cleaning brush to the cleaning rod, dip the brush in
bore-cleaning solution, and clean the chamber. Use a minimum of ve plunge
strokes and three 360° clockwise rotational strokes.
6. Repeat steps 2 and 3 above.
7. Use an all-purpose nylon cleaning brush and rearm-cleaning solution to clean
all carbon and powder residue from inside the action, barrel extension,
bolt locking lugs, extractor, and outside of the bolt assembly.
IMPORTANT: DO NOT USE A WIRE BRUSH ON ALUMINUM SURFACES
SUCH AS THE MINI-CHASSIS AND BOTTOM METAL. IF CLEANING IS
NECESSARY, AVOID SCRATCHES AND WEAR BY USING A SMALL NYLON
BRUSH OR FLANNEL PATCH.
8. Wipe all components clean and dry and inspect them for excessive wear,
corrosion or mechanical damage. If any of these conditions are discovered, have
them corrected before ring again. (See Servicing and Repair later in this section.)
9. Lightly dampen a annel patch with gun oil and pass it once through the barrel,
leaving a thin lm of oil on the inside surface. Leave this lm of oil on the surface if
rearm is to be stored. If it is not being stored, or if it is being removed from storage
for use, pass the dry patch through the barrel and chamber to remove as much
excess oil as possible.
10. Check that annel or brush bristles have not become lodged in any part of rearm,
then lightly lubricate (See Section 5.4).
11. Remove any gun-cleaning solution, and ngerprints from the outside surfaces of
the rearm. (Finger moisture, if left, could start a corrosion process.)
12. Reassemble the rearm:
a. Depress bolt stop on left side of action, and slide bolt assembly
in from the rear.
b. Lock the bolt into the chamber.
c. Cycle the action a few times to ensure proper function.
WARNING: BE SURE TO REMOVE OR NEUTRALIZE ANY AMMONIA-BASED
CLEANING SOLUTIONS FROM THE FIREARM AS THEY CAN CAUSE
PERMANENT DAMAGE.
OPTIONAL BUT RECOMMENDED EQUIPMENT:
• Bore guide: this helps to prevent users from damaging the barrel
by keeping cleaning rod in line with the bore.
• Bore light: inserted at muzzle, a bore light will help user inspect riing from
the rear of receiver while keeping rearm pointed in a safe direction.
• Chamber mop: helps clean chamber and lead more effectively than
chamber brush alone.
PROCEDURE:
WARNING: ENSURE THAT THE FIREARM IS NOT LOADED.
WARNING: ALLOW FIREARM TO COOL TO ROOM TEMPERATURE
BEFORE ATTEMPTING CLEANING/MAINTENANCE.
WARNING: USE PROPER PROTECTIVE EQUIPMENT: GOGGLES, MASK,
AND CHEMICAL GLOVES.
WARNING: IMPROPER CLEANING TECHNIQUES CAN PERMANENTLY
DAMAGE FIREARM AND LEAD TO DEGRADATION IN ACCURACY
AND REDUCED LIABILITY.
WARNING: CLEANING FIREARMS, DISCHARGING FIREARMS IN POORLY
VENTILATED AREAS, OR HANDLING AMMUNITION MAY RESULT IN
EXPOSURE TO LEAD AND OTHER HARMFUL SUBSTANCES WHICH ARE
KNOWN TO THE STATE OF CALIFORNIA TO CAUSE BIRTH DEFECTS,
REPRODUCTIVE HARM, AND OTHER SERIOUS PHYSICAL INJURY. HAVE
ADEQUATE VENTILATION AT ALL TIMES. BE SURE TO ALWAYS WASH
HANDS THOROUGHLY AFTER POSSIBLE EXPOSURE.
1. Strip for cleaning as previously described, removing the bolt assembly
from the action.
Note: Avoid contact between the cleaning rod and the muzzle as resultant
wear will greatly reduce accuracy.
2. Attach a cotton annel patch to end of the cleaning rod, insert it in the chamber
and pass the rod and patch down through the barrel and out the muzzle. Remove
used patches at muzzle to avoid pulling it back through the bore. Repeat, changing
patches with each pass through the barrel, until the last patch comes out clean.
Note: Avoid pulling dirty patches back through the barrel.
3. Visually inspect the barrel; if it is clean, proceed directly with step 8, but if it
remains dirty, continue with step 4.
