Manual

ammunition now manufactured has a noncorro-
sive primer which makes cleaning easier, but no
less important. The primer still leaves a deposit
that may collect moisture and promote rust if it is
not removed. The cleaning described below will
remove all deposits except metal fouling which is
relatively uncommon and is removed by mainte-
nance personnel.
(1) Chan&r. Remove the patch holder
from the cleaning rod and insert two
patches about halfway through the slot.
Dip the patches in bore cleaner, then
wring or squeeze the excess fluid from
the patches.
Screw the Ml0 cleaning rod
together (less the patch holder) and in-
sert it all the way into the bore.
Flare
the patches out, then insert the patch
holder with the wet patches into the
chamber. Push the threaded end into
the chamber until it touches the cleaning
rod. Hold it there with one hand and
screw the cleaning rod and the patch
holder together.
Pull the patches to the
chamber; at the same time turning the
rod clockwise. Turn the rod several
times, wiping the chamber thoroughly.
After the chamber has been thoroughly
cleaned use the chamber brush in the fol-
lowing manner :

Screw a section of the Ml0 cleaning
rod into a threaded hole of the driver
ratchet.
Place the brush into chamber of the
barrel.
Allow the rifle bolt to close slowly
against the end of the driver ratchet.
Using the rod section as a handle, ro-
tate the driver clockwise and counter-
clockwise to loosen and clean residue
from the chamber.
(2) Bore.
To clean the bore saturate the
bore brush with cleaning compound sol-
vent (rifle bore cleaner) and-

Insert the bore brush into the cham-
ber. Insert the cleaning rod into the
bore and screw the brush onto the rod.
Pull the brush through the bore.
Re-
move the brush and repeat the pro-
cedure as often as required to clean
the bore.
(c) Then use one cleaning patch dampened
with bore cleaner in the following
manner :

1. Place the patch in the patch holder
and insert it into the chamber.
S. Insert the cleaning rod (less the patch
holder) into the bore and screw it
onto the patch holder.
3. Pull the cleaning rod through the
bore. Repeat this procedure using
as many patches as required until
the patches come through the bore
clean.
Gm cylinder lock xrew with vaZve aa-
mnb&y. Remove carbon deposits by us-
ing bore cleaner, then wipe the part and
oil it lightly (do not use abrasives).
Check the valve to see that it is not held
open by particles of dirt or sand.
Piston of operating rod.
Remove carbon
from the piston with bore cleaner. Take
care not to damage the piston. Oil it
lightly after cleaning (do not use abra-
sives) .
Gas cylinder. Clean the gas cylinder
with bore cleaner and patches.
Face of the bolt. Clean the face of the
bolt with a patch and bore cleaner, pay-
ing particular attention to its inside
edges. Remove the bore cleaner with dry
patches and oil the part lightly.
AU other parts.
Use a dry cloth to re-
move all dirt or sand from other parts
and exterior surfaces.
Apply a light coat
of oil to the metal parts and rub raw
linseed oi2 into the wooden parts. Care
must be taken to prevent linseed oil from
getting on metal parts.
Cleaning frequency. The rifle must be
thoroughly cleaned no later than the
evening of the day it is fired.
For three
consecutive days therafter check for evi-
dence of fouling by running a clean patch
through the bore and inspecting it.
The
bore should be lightly oiled after each
inspection.
23. Normal Maintenance
a. When in use, the rifle should be inspected
daily for evidence of rust and general appearance.
A light coat of oil (PL Special) should be main-
tained on all metal parts.
