Picture of Easy and Cheap airsoft Silencer
Just to warn you airsoft silencers dont actully silence the gun they ethier muffle the sound or its just for looks this one is both. The reason the silencers only muffle is because most of the noise is created within the gun so silencers cant make it completely silent

Cut the pvc to your desired length. cut the straw a little bit over the lengh of the pipe approx. 1/2 in.

Step 3: Inserting insilation

cut pieces of insulation that will fit around the straw. put one at a time and push it into the pipe as you go along until full.

Step 4: Taping the inserting part of the straw

now tape the part that will go into the gun(note if the staw is allready snug skip this step)

It looks awesome, but do you know if it works for a fairground shotgun?

it should is it tri shot?
It is made to shoot one bullet, but I modded it so it should be able to shoot double. I don't think it's tri shot

dude it does work with co2 because the noise is the escaping co2 I have a fake co2 silencer because my mom though if I make a real one it might be faulty and I will blow my hand off (blow my hand off is just exajeration).
my co2 paintball gun is pretty quieted now after i affixed a modfied one of these to the end
I made a co2 pistol silencer and it worked surprisingly well. Not to mention I still have both my hands.
nice pretty funny
