If necessary, clean the chamber and locking lugs using a Mil-Standard
M16 style chamber brush. Properly apply CLP to the brush and insert it
into the chamber. Rotate the brush in a clockwise direction several
times and remove.
4. After all fouling has been removed, the chamber and bore should be
wiped dry. When the bore is dry, pass a patch that is lightly lubricated
with CLP through it for preservation.
5. Inspect the barrel and chamber to be certain no patches have
inadvertently been left in them. Remove any that remain.
6. Use a small brush or rag to remove dirt and foreign matter from inside
the receiver and other parts of the action. Lightly lubricate all moving
parts with CLP.
7. Use a small brush and CLP to clean the bolt and bolt carrier. Wipe dry
and reassemble.
8. Use a cleaning cloth to clean the gas piston. It may be necessary to use
a bronze bristle brush to remove carbon build up from the piston.
Notice! DO NOT APPLY LUBRICANT TO THE GAS PISTON,
GAS REGULATOR OR GAS BLOCK, THESE COMPONENTS ARE
NOT TO BE LUBRICATED IN ANY WAY. USING LUBRICATION
IN THE GAS SYSTEM COULD
DAMAGE YOUR RIFLE.
9. Inspect the gas ports in the gas
regulator to ensure they are
free of debris and carbon
build-up. If the ports are fouled,
it may be necessary to use a
dental pic to remove carbon
build up (Figure 39).
20.1. CLEANING PROCEDURES
Your SCAR 16S will function better, more reliably and be more accurate over
a longer period of time if it is properly maintained and kept clean. Clean your
firearm after every day of shooting, and more often if it becomes excessively
dirty during your shooting session. A minimum cleaning includes wiping
down the firearm and lubricating key parts. Regular maintenance will also
include cleaning the barrel and gas system.
If you encounter a function problem be sure to give your firearm a thorough
cleaning to see if it solves the problem before seeking the services of the
FNH USA Service Facility in Arnold, Missouri, or a qualified gunsmith.
1. Remove the magazine and make certain the rifle is completely
unloaded and the “safety” selector is in the on safe position as
explained in Section 9.
2. Disassemble the rifle as explained in Section 19.
3. Inspect the chamber and bore for powder fouling. A normal amount of
powder residue can be expected and is not serious. It can usually be
removed with a patch and CLP (cleaner, lubricant and protectant).
Use a rifle cleaning rod with a brass jag and patch large enough for a
snug fit in the bore. Apply a small amount of CLP and insert the rod and
patch into the barrel from the breech end and run it back and forth
several times. Care should be exercised to ensure that the cleaning rod
does not strike the crown of the muzzle, as damage to this area can
adversely affect the accuracy of the rifle.
If, or when, fouling should become heavy, it can be removed with a
bronze bore brush. Dip or spray the brush with CLP and scrub the
chamber and bore until the fouling is removed. To prevent bronze
bristles from breaking off, the brush should be pushed completely
through the barrel before being withdrawn.
Notice! DO NOT USE A STAINLESS STEEL BRUSH TO CLEAN
THE BORE. IT COULD DAMAGE THE CHROME PLATING.
