he canopy is more than a door to
your Avenger’s turret. It seals out gases
from missile exhaust and is your only
window for sighting targets. If the
canopy leaks or becomes so scratched
that you can’t see through it, you’re in
a world of hurt.
So, protect your canopy. Here’s how:
Keep it covered. That’s the best
thing you can do. Blowing sand scours
the canopy and soon it’s clear as mud.

Look for the C-clips on the canopy
hinges before you go to the field. They
often pop off. Without the clip, the
hinge pins can work out. Your repair-
man can replace the clip in minutes.

a handhold when you climb in or out
of the turret. That can damage the
mounting brackets, too.
Check for leaks. You don’t want to

the canopy with the lanyard only—and
do it gently. If you let the canopy
spring open or slam shut repeatedly,
the canopy’s mounting brackets get
damaged. So, guide the canopy in

before you move the turret or the ve-

In areas where powerful winds are
common, give the canopy extra pro-
tection with sleeping mats. Cut an old
sleeping mat in half and put the pieces
between the tarp and the canopy.
If your tarp still has metal fasteners,
get them replaced with plastic hooks.
The metal fasteners will scratch the
canopy. Plastic hooks from the
HMMWV cargo cover work great. If
your local canvas shop doesn’t have
the hooks as bench stock, order them
