Low Signature Systems (Silencers) by the Jolly Roger


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:

---------

1) Drill hole in grenade container at both ends to fit outside diameter

of pipe nipple. (see table 1)

5 in.

 

2) Drill four rows of holes in pipe nipple. Use table 1 for diameter and

location of holes.

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.

 

How to use:

----------

 

1) Thread the low signature system on the selected weapon securely.

2) Place the proper cotton wad size into the muzzle end of the system

(see table 2)

3) Load weapon

4) Weapon is now ready for use
