MGS
Something you never want to mess
up is the MGS cable. It costs thou-
sands to replace. That’s why there’s
the cable adapter, NSN 5935-01-117-
3304. It protects the cable’s pins.
Make sure that the adapter’s installed
before you go to the field. If it’s miss-
ing, tell your repairman. He’ll get sup-
port to lock wire a new adapter to the
cable’s connector.
Traversing Unit
Don’t set the TU on its lock or cable.
That breaks the lock or damages the
cable’s wiring. Set the TU on its side
with the lock up.
Check for adapter before going to field

Don’t force the knobs on either sight.
Too much muscle breaks the op sight
AZIMUTH and ELEVATION knob
stops and makes it hard to center them.
Too much force also locks up the night
sight AZIMUTH and ELEVATION
knobs and bends the shaft to the
RANGE FOCUS knob. If any of the
sights’ knobs are hard to turn, clean
under them with 30 psi air.

Unless you’re in combat, never ride
around with the sights mounted. If the

In the rain, keep the MGS covered
as much as possible. MGSs aren’t al-
ways waterproof. Moisture damages its
circuitry.

Launch Tube
Don’t stick the launch tube down the

That can chew up the lip of the
