Dear Editor,
It can be confusing when you boresight the Bradley’s coax machine gun
mount. There are two boresighting adjustment knobs, but they aren’t
marked. You’re forced to experiment to figure out which knob adjusts
elevation and which adjusts azimuth.
We ended the knob
confusion with this
simple sign:
The sign tells you
to turn the elevation knob
to the right (clockwise)
to tilt the muzzle up and
to the left (counter-
clockwise) to tilt it down.
Turn the azimuth knob
up (clockwise) to move the
muzzle to the left and down (counter-clockwise) to move it to the right.
Use a permanent marker to write the directions on the inside of the
door to the boresighting knobs.

echanics, when it’s time to install the armor tile brush guards on M2A2/
M3A2 Bradleys, you’ve got your work cut out for you.
During production, threaded holes were drilled in the Bradley’s armor for
mounting the brush guards. Plastic inserts were plugged into the holes to keep
the threads from corroding.
It didn’t work. Replacing the inserts with setscrews didn’t work either. The
corrosion problem continued. Now, you face the difficult task of peeling out the
plastic inserts or drilling out stuck setscrews.
Don’t put it off, though. The longer the inserts and setscrews stay in place, the
worse the corrosion will get.
Once they’re out, replace each insert and setscrew with a bolt, NSN 5305-00-
724-7219, and lockwasher, NSN 5310-00-232-8194. Apply some antiseize com-
pound, NSN 8030-00-597-5367, to the threads before installing the bolt. That
puts a stop to the corrosion and makes removal a little easier.

I think we can sign off on your
suggestion. Thanks.
