5. After all leading and plastic residues have been removed, run a clean,
dry patch through the bore. Follow this with a final, lightly oiled patch.
6. Inspect the barrel and chamber to be certain no patches have
inadvertently been left in them. Remove any that remain.
7. Reassemble your P-12 shotgun and wipe all exposed metal surfaces
with an oiled cloth making sure to wipe away all finger marks where
moisture could accumulate. Any dried oil in the receiver area should
also be removed.
8. Lightly oil your firearm at the points described in Section 7.1. Regular,
light oiling is extremely important to the durability and reliable
operation of your P-12 shotgun.
21.2. ADDITIONAL DISASSEMBLY
One of the advantages of the P-12 is the ability to disassemble the action
for cleaning.
Make sure you have a clean place to work and a good place to put the
components as they are disassembled as shown in Figure 12 on page 38.
21.3 REMOVAL OF THE BARREL
1. Unscrew and remove the magazine cap. Remember, always keep the
end of the magazine pointed in a safe direction.
2. Slide the barrel forward, withdrawing the barrel from the receiver
and disengaging the barrel bracket from the front end of the
magazine tube.
3. Immediately screw the magazine cap back onto the magazine tube at
least three full turns.
Normal maintenance can be accomplished with the barrel still attached to
the receiver (oiling and wiping down). More careful cleaning requires
removal of the barrel from the receiver (cleaning the barrel). A complete
cleaning requires removal of the bolt and trigger group.
If you encounter a function problem such as a tight action when working the
forearm be sure to give your firearm a thorough cleaning to see if it solves
the problem before seeking the services of our FNH USA Service Facility or
your department armorer.
1. Place the “safety” in the on safe position. Open the action and
inspect the chamber and magazine to make certain they do not
contain any shells. Keep the muzzle pointed in a safe direction.
2. Remove the barrel as explained under “Basic Disassembly” in
Section 19 and under “Removal of the Barrel” in Section 21.3.
3. Inspect the bore from both ends for leading and plastic residue that
often remain in the bores from the shot cups in modern shells. Leading
and plastic residue will appear as longitudinal streaks and are usually
more predominant near the muzzle and just forward of the chamber.
A normal amount of either is common and not serious.
4. If leading or plastic residue seems excessive you can remove it by
brushing the bore with a brass brush. Soak the brush or spray the bore
with a powder solvent first. Scrub until clean. To prevent bristles from
breaking off, push the brush fully through the barrel each time before
pulling it back through.
