DETAILED CLEANING TECHNIQUES…

NOTE:
The procedures below describe cleaning with a standard military issue type
multi-piece rod cleaning kit. Other commercial cleaning kits may include alternate
cleaning instructions which may be just as eective.
CLEANING THE BORE:
The bore of your ACR 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 dicult to
push
a new, sti
Bore Brush through the Bore. You will find it much easier, and more eective, 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.
To make cleaning the Bore easier, you may remove the barrel from the
Upper and replace once the Bore and Chamber are cleaned. The zero of
the barrel will not be lost.
ALWAYS CLEAN FROM THE 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 or Barrel Assembly 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 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”.
