PATS Video Online
CBRN specialists used to get a DVD with their new M41 protection assessment test system
(PATS) that explained how to use PATS. Unfortunately, the DVD often disappeared. The
good news is you can now view the video online:

Dear Editor,
TACOM’s Maintenance Action Message 12-049 about the sluggish
operation of the M2A1 machine gun required maintenance to check the
weapon’s headspace. While doing this, we discovered that several breech
locks needed to be replaced.
When you replace the breech lock, you’re also supposed to replace the
spring pin, NSN 5315-01-541-7233. It’s shown as Item 18 of Fig 1 in
TM 9-1005-347-23&P. Unfortunately, the spring pin’s NSN is no
longer good.
We checked with TACOM
and they said you must now
order the spring pin with
Keep in mind that NSN brings
100 pins.

Dear Editor,
On Page 41 in PS 720 (Nov 12), you pointed out that the M2/M2A1
machine gun bolt latch with the fixed clearance hasn’t been manufactured for
20 years. When units order the bolt latch, NSN 1005-00-550-4060,
they should receive one which has an adjustable clearance.
This is all correct.
But it turns out there are still some of the old bolt latches in the field and
on new weapons coming from Anniston Army Depot. We have had several
questions about if it’s OK to continue to use the old bolt latch. It is. Use
it until it wears out and then replace it with the adjustable bolt latch.
