BOG cleaner (cleaning compound solvent
(CR) ) is used primarily for cleaning the
bore; however, it may be used on all metal
parts for a temporary (l-day) protection
from rust.
Hot, soapy water or boiling water is no
substitute for bore cleaner and wiZZ only
be uaea? w&n bore cleaner <is not available.
Drycleaning solvent is used for cleaning
rifles which are coated with grease, oil,
or corrosion-preventive compounds.
Stubborn carbon deposits are removed by
soaking in carbon removing compound
(PCIII-A) and brushing. This process
must be followed by the use of dryclean-
ing solvent.
Caution: Individual protective meas-
ures must be taken when using com-
pound PCIII-A.
b. Lubricants.
(1) Lubricating oil, general purpose (PL
special) is used for lubricating the rifle
at normal temperatures.
(2) Lubricating oil, weapons (LAW) is used
for low temperatures (below 0’).

expedient under combat conditions when
the oils prescribed in (1) and (2) above
cannot be obtained.

weapon should be cleaned and lubricated
with the proper lubricants as soon as
possible.

working surfaces shown in figure 33.
