Cleaning and Lubing
Solvent can make cleaning off carbon easier, especially on the bolt. Just don’t dunk
the bolt in a solvent tank. Too much solvent ruins the bolt’s track assembly gears,
which means a trip to support. If you do use a solvent, use a rag and brush.
But
once
you’re
through
cleaning,
you
gotta
lube
the
M242. GMD isn’t pleasant to
work with, but your M242 will
corrode if you don’t use it. The
barrel is especially prone to rust
and needs a light coat of GMD
inside the locking lugs and barrel
support bearings. Use CLP on the
rest of the barrel.
Assembly, Disassembly
Pull the lower straight drive shaft down
only when you’re installing or taking off the
feeder. And then put the drive shaft back up
ASAP. If you leave the shaft down, it can
easily get bent.
When you install the feeder, make sure it’s
correctly installed on the receiver before you
push up the lower straight drive shaft. If the
shaft doesn’t want to go up, the feeder isn’t
positioned right. Reposition it and try again.
Once the drive shaft
handle
is
locked
in
place, the feeder handle
should lock in the down
position
easily.
If
it
doesn’t, your repairman
needs to check it out.
If you try to force the
feeder
handle
down,
you could damage the
14-pin connector.
If you set the gun at
30 degrees, that makes
it
easier
to
maneuver
the feeder on and off.
When you remove the feeder,
make sure its handle is in the down
position before you lay the feeder
on the ground. That protects the
feeder’s 14-pin connector, which is
easily damaged.
If you
use solvent,
clean with
a rag and
brush,
not
a
solvent
tank
M2/M3-Series Bradley…
Keep Big Gun Ready
With a Little PM
Put feeder handle
down before putting
feeder on ground
Pull drive shaft handle down only
when installing or removing feeder
Reposition feeder and try again
if drive shaft handle doesn’t want to go up
But
remember:
More is
not
better when it
comes to lube.
Too much lube
attracts sand,
which leads to
jamming and
a
very
dirty
weapon.
Your Bradley’s M242
machine gun makes a
lot of noise
when it’s
firing, but a lack of
PMCS can
silence
it in
a hurry.
Here are some
tips to take care
of the M242 so
it’s ready to take
care of you when
the time comes.
A
light
coat of GMD
is all that’s needed
on the outside of the
breech and locking
lugs.
Do
not
lube the face
of the bolt—that
causes malfunctions!
there ya go.
Your PM is
done!
great! now
I’m ready for
anything!
