NOTE: The procedures below describe cleaning with a standard military issue multi-piece
rod cleaning kit. Other commercial cleaning kits may include alternate cleaning
instructions which may be just as effective.
CLEANING
THE
BORE:
The
bore
of your Bushmaster rifle has Lands and Grooves called
rifling. Rifling makes the bullet spin very fast as it moves down the Bore and down
range. It is difficult to
push a new
, stiff Bore Brush through the Bore. You will find it
much easier, and more effective, to
pull your
Bore Brush through the Bore
. Also,
because the brush will clean better if the bristles follow the grooves (this is called
tracking), you want the Bore Brush to be allowed to turn as you pull it through.
ALW
AYS CLEAN FROM FROM CHAMBER TOWARD THE MUZZLE.
Follow these
steps:
1.
Attach three Rod Sections together but leave each one about two turns short of being
tight. Attach the Patch Holder but leave it two turns short of tight also.
2.
Point Muzzle down. Hold the Upper Receiver in one hand while inserting the end of
the Rod with Patch Holder attached into the Chamber. Guide the Rod carefully
through the Bore.
CAUTION:
Do not let the Rod or its threaded end scratch the
Chrome Lining of the Bore or Firing Chamber. About 2 - 3 inches of the Rod should
protrude out of the Muzzle.
3.
Attach the Handle Section of the Cleaning Rod to the end of the Rod sticking out of
the Muzzle, and swab out the Bore with a patch moistened with “CLP”.
4.
Remove Patch Holder and attach Bore Brush (leaving it two turns short of tight).
5.
Pull the Brush through the Bore and out the Muzzle. You should be able to see the
Rod twisting as you pull it - this is the Brush "tracking" in the rifling.
NEVER
reverse the direction of the Bore Brush while it is in the Bore.
