Do
Change Machine Gun Barrels at Range and
Keep Barrels Matched to Receiver
Many M249, M240 and M2
barrels
are
ruined
every
year
because units go the range and
fre hundreds oF rounds through
the same barrel. A single barrel
can cost $800. Simply switching
barrels, which takes just seconds,
can save your unit money and
grieF From your CO.
Don’t
Grab Just Any Barrel
The M249 and M240 barrels have been headspaced to a specifc weapon. IF you
use the wrong barrel, you could damage the weapon and injure yourselF.
Even with the new M2A1, which
can
use
any
M2A1
barrel,
it’s
a
good idea to use only the two barrels
dedicated to that particular M2A1.
That
will
save
you
accountability
problems later when you turn in the
two barrels For that specifc M2A1.
All
barrels
should
have
a
dog
tag with the serial number For their
weapon. It’s a good idea to use a
marker
to
highlight
the
receiver’s
serial number so Soldiers can quickly
fnd it.
Don’t
Lock Bolts Back for Storage and Transport
IF
bolts
are
leFt
lockedback,thesprings
can’t
relax
and
soon
have
to
be
replaced.
But even worse, iF the
bolt
is
locked
back
and
someone
Forgot
to
remove
a
round,
the weapon can fre iF
the truck hits a bump
during transport. This
happened at ±t Stewart.
