3) Thread one of the pipe couplings on the drilled pipe nipple.
|
||
|
|
4) Cut coupling length to allow barrel of weapon to thread fully into low
|
||
|
|
signature system. Barrel should butt against end of the drilled pipe
|
||
|
|
nipple.
|
||
|
|
5) Seperate the top half of the grenade container from the bottom half.
|
||
|
|
6) Insert the pipe nipple in the drilled hole at the base of the bottom
|
||
|
|
half of the container. Pack theabsorbent cotton inside the container and
|
||
|
|
around the pipe nipple.
|
||
|
|
7) Pack the absorbent cotton in top half of grenade container leaving
|
||
|
|
hole in center. Assemble container to the bottom half.
|
||
|
|
8) Thread the other coupling onto the pipe nipple.
|
||
|
|
|
||
|
|
Note: A longer container and pipe nipple, with same "A" and "B"
|
||
|
|
dimensions as those given, will furthur reduce the signature of the
|
||
|
|
system.
