ust because the receiver rails on the
Bradley’s M242 automatic gun are a
little banged up doesn’t mean the re-
ceiver needs repair, armorers. A little
damage is OK.
As long as the banged-up area is no
longer than six inches or no deeper
than
1
/
2
inch, the receiver is good to
go. This info is being added to the re-
vision of TM 9-1005-200-20&P.
But you can avoid even slight damage by telling your crews to always elevate
the M242 to 200-300 mils before installing the feeder. That protects the rails.
ibration, that old enemy of every
crewman and mechanic, has struck
again. This time the victim is the
mounting screws on the cargo hatch
latch catch of M2A2 and ODS
Bradleys.

Remove the screw and measure it.
The correct screw will be exactly 1

inches long.
NSN 5305-00-725-2317 brings 100
of the right screws. Make sure you use
a flat washer, NSN 5310-00-080-6004,
with each screw and torque the screws
to 32–34 lb-ft.
The screw and washer NSNs aren’t
listed in the parts TMs, so make a note
until they can be added.
Here’s what to look for:
m
Eyeball the head of the screw. It
should have six dashes indicating a
grade 8 screw. Anything else should
be replaced.
Mechanics, before you tighten the
screws, make sure the right ones were
used in the first place. Some vehicles
have screws that are the wrong grade,
the wrong size, or both. Either can re-
sult in loose screws.
Feel for loose screws
on hatch latch catch
Six dashes equals grade 8
Crewmen, try moving the screws
with your fingers. Then look for shiny
marks around the head of the screws.
Shiny areas indicate movement. Report
loose screws to your mechanic.
Loose screws keep the cargo hatch
from locking down. If it won’t lock
down, your Bradley is NMC, so make
a habit of checking the screws after
every operation.
