Dear Editor,
There is a mistake in the M500 shotgun’s TM 9-1005-338-13&P that
will cause major round ejection problems.
In the section on bolt assembly
in WP 0029 00-1, the right- and
left-hand
cartridge
extractors
are reversed in the picture.
If
the extractors are put on like the
picture shows, it will take a very
hard pump of the shotgun to eject a
round.
Plus, this wrong position will
eventually damage the extractors.
Armorers need to correct this in
their TMs so they don’t make this
mistake.

Dear Chief T.K.,
Certainly. Both the ACOG and the RCO (riFe combat optic) are covered by TM
9-1240-416-13&P. It’s on the LOGSA ETM site:
Here are the available ACOG repair parts and their NSNs:
Radiation Warning
The ACOG contains a small amount of tritium gas. If the tritium source breaks
or no longer illuminates, notify the local radiation safety of±cer immediately.
Anyone who has handled an ACOG with a broken tritium source should wash
thoroughly with non-abrasive soap and lukewarm water. Anyone handling the
damaged ACOG should wear rubber or latex gloves. The ACOG and gloves should
then be double-wrapped in plastic and put in a sealed container labeled BROKEN
TRITIUM DEVICE–DO NOT OPEN.
The safety of±cer should contact Trijicon for shipping instructions for the
damaged ACOG. Call (800) 388-0563.
Dear Half-Mast,
We have several ACOGs (advanced combat optical gunsights) that need
minor repairs or are missing parts, but we can’t find any information on
fixing them. Can you help?
CW2 T.K.
Editor’s note:
Absolutely, Mr. Weston.
Make sure you make this change, armorers.
This will be corrected in the next revision of the TM.
