Dear Editor,
The Army has come out with a
great card for M2 gunners that
lists the whole headspace and
timing procedures. The problem is
that usually the cards make it out
to the field just one time and then
they disappear.
We suggest that in a non-
combat situation armorers punch a
hole in the cards and use a chain
or 550 cord to secure them to
the M2’s trigger handles. That way
the cards will stay with the M2s
longer.
We have one other suggestion:
The M2 barrel threads are
constantly getting banged up.
It’s a good idea to cut a plastic
sports bottle in half and stick one
half over the barrel threads when
the barrels aren’t installed. That
keeps burrs from developing on the
threads. Burrs make it difficult–if
not impossible–to screw in the
barrel. Of course, it’s important
not to toss barrels around or leave
them rolling around in the back of a
truck, which happens too often.
Finally, we know all M2s are supposed
to have a warning sticker now concerning
headspace and timing. But how do you get
the stickers?

Editor’s note:
First, let’s
take care of your question.
Order the warning stickers
with NSN 9905-01-573-
6847. That brings 25
stickers.
Those smart cards with
the whole headspace and
timing procedure can be
ordered by your pubs clerk
with GTA 09-06-045.
Using a sports bottle as
temporary protection for
the barrel threads is ±ne,
but the best ±x is to get
SoftCaplugs, NSN 5340-
01-552-0082. They are
speci±cally designed to
protect barrel threads.
Thanks for the great
suggestions. Good
headspacing on your part!
WARNING
To prevent damage to parts and/or injury to personnel,
