25.1 Receiver and Feed Tray Cover Assembly
With the receiver and feed tray cover disassembled, use an all
purpose brush or compressed air to remove loose debris from
the feed tray cover mechanism. Use a plastic bristled cleaning
brush and military-grade cleaner/lubricant to clean debris and
excess lubricant from the feed tray and cover, paying close
attention to not dislodge captive springs in the cover
mechanism. Aerosol gun cleaners and compressed air will aid
on removing debris and excess lubricants from around these
parts.
Use a plastic bristled cleaning brush and military-grade
cleaner/lubricant to clean debris and excess lubricant from the
interior of the receiver, paying close attention to the interior
rails. Aerosol gun cleaners and compressed air will aid on
removing debris and excess lubricants from inside the
receiver. Dry, clean cloths can be used to wipe out the interior
of the receiver.
Use a plastic bristled cleaning brush and military-grade
cleaner/lubricant to clean debris and excess lubricant from the
exterior of the receiver and the moving parts such as the
charging handle, dust cover and magazine well cover. Aerosol
gun cleaners and compressed air will aid in removing debris
and excess lubricants from these parts. Dry, clean cloths can
be used to wipe off the exterior of the receiver.
Use a plastic bristled cleaning brush and military-grade
cleaner/lubricant to clean debris and excess lubricant from the
rear sight assembly.
When clean, apply military-grade cleaner/lubricant to the
following parts. See Figures 70.A-B. Apply a thin film of CLP to
all external metal parts.
25.2 Drive Springs and Guide Rod
With the guide rod and springs removed and separated, use
an all purpose brush and military-grade cleaner/lubricant to
remove debris and excess lubricant from the springs and
guide rod. Compressed air or aerosol gun cleaners can be used
to assist in cleaning these parts. Dry, clean cloths should be
used to wipe off any excess lubricants and fouling.
When clean, apply thin film of military-grade cleaner/lubricant
to the exterior of all parts.
25.3 Moving Parts Assembly
With the moving parts assembly removed from the receiver
and separated as explained in Section 24, clean away debris
and fouling using an all purpose brush and military-grade
cleaner/lubricant. Compressed air or aerosol gun cleaners can
be used to assist in cleaning these parts. Dry, clean cloths
should be used to wipe off any excess lubricants and fouling.
The bolt face and extractor
should be cleaned with an all
purpose brush or pipe-cleaner,
ensuring the extractor is free
of debris. See Figure 71.
Use an all purpose brush and
military-grade cleaner/
lubricant to remove debris,
fouling and excess lubricant from the slide hammer. The bolt
carrier and piston body can be cleaned in the same way.
Use the optional scraper tool to clean fouling and carbon from
the piston grooves. See Figure 72. Use the flat end of the
scraper tool to clean carbon and fouling from the interior of
the piston face. See Figure 73. If this scraper is not available,
use universal scrapers or bronze bristled brushes to clean the
piston. Do not use abrasives.
When clean, apply military-grade cleaner/lubricant to the
following parts. See Figure 74. Apply a thin film of lubricant to
all external metal parts. Do not lubricate the chrome-plated
piston head.
25.4 Barrel
With the barrel removed from the receiver and the heat shield
removed from the barrel, use an all purpose brush and
military-grade cleaner/lubricant to remove debris and excess
lubricant from the exterior of the barrel. Use an all purpose
brush to clean inside the barrel extension and locking lug
area. See Figure 75.
Use a cleaning rod and bore
brush soaked with military-
grade cleaner/lubricant or
bore solvent to clean the
interior of the bore. Use a
cleaning rod and chamber
brush soaked with military-
