Low signature systems (silencers) for improvised small arms weapons
can be made from steel gas or water pipe and fittings.
Material Required:
- Grenade Container
- Steel pipe nipple, 6 in. (15 cm) long - (see table 1 for diameter)
- 2 steel pipe couplings - (see table 2 for dimensions)
- Cotton cloth - (see table 2)
- Drill
- Absorbent cotton
Procedure:
- Drill hole in grenade container at both ends to fit outside diameter
of pipe nipple. (see table 1)

5 in.
- Drill four rows of holes in pipe nipple. Use table 1 for diameter and
location of holes.
(Note: I suck at ASCII art!)
6 in.

- Thread one of the pipe couplings on the drilled pipe nipple.
- 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.
- Seperate the top half of the grenade container from the bottom half.
- 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.
- Pack the absorbent cotton in top half of grenade container leaving
hole in center. Assemble container to the bottom half.
- 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.
How to use:
- Thread the low signature system on the selected weapon securely.
- Place the proper cotton wad size into the muzzle end of the system
(see table 2)
- Load weapon
- Weapon is now ready for use
