Gun Silencers
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.
- 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
-
Drill hole in grenade container at both ends to fit outside diameter of pipe nipple. (see table 1)
-> /----------------------\ / | | 2.75 in | ) ( <-holes dia. \ | | -> \-----------------------/ |-----------------------| 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. |-----------------------------------| _____________________________________ ___ | O O O O O O O O O O O O O O O O O | | C (nom. dia.) ------------------------------------- (size of hole) | \ / (space between) B (dia.) A
-
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.
- 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
