Dear Editor,
I review Army Materiel Status System (AMSS) information as I travel
around to units with the MIARNG. A common problem I find is that units
have the wrong NSN listed for their MK 19s.
When the MK 19 had MWO 9-1010-230-50-1 applied, its NSN
was changed from 1010-01-126-9063 to 1010-01-490-9697, its
model from MK 19 to MK 19 MOD3, and its end item code (EIC) from
4AE to 4BL.
But when you look up the MK 19’s line item number (LIN) of M92362
on the Maintenance Master Data File (MMDF), it has the NSNs and EICs
reversed. So the wrong NSN and EIC are often entered into SAMS-E.
Armorers need to double check that they have NSN 1010-01-490-
9697 and EIC 4BL listed for their MK 19 MOD3s. All MK 19s should
have been modified by now.

Editor’s note:
Good point, Sergeant.
Making this correction now, armorers,
can save you headaches later.
Dear Editor,
Sometimes units turn in their M203 grenade launchers for annual gaging
without their host weapons, the M16 rifle or M4/M4A1 carbine.
That causes a problem. If the M203s are not left on the weapons, we
can’t verify that the M203s are properly mounted. We have seen M203s
mounted so loosely that the host weapon’s barrel nut was damaged. And we
have seen other M203s whose quick-disconnect bracket was so tight that
the host weapon’s barrel straightness gage couldn’t pass through.
So please tell units to leave the M203s on the host weapon when they
turn it in for gaging. That way we can make sure the M203s are in good
shape and mounted correctly.

Editor’s note:
Good tip, Peter. We
will gladly pass it on to armorers.
Dear Half-Mast,
The blank firing attachments (BFA) for our M2 machine guns have some
parts that need to be replaced. We can’t find anything in the M2 TMs.
Where can we find parts info?
SFC D.S.
Dear Sergeant First Class D.S.,
The M19 BFA actually has its own TM, TM 9-1005-314-13&P (Feb 10), which
lists all the repair parts. You can fnd the TM at the ETM site:
The repair parts are listed in WP 0010 00.
Where’s the BFA?
