Introduction: A Working Silencer for Your CO2 Airsoft Gun

Picture of A Working Silencer for Your CO2 Airsoft Gun

Ever wondered why a trombone is fluted at the end? Well, I can tell you that its not just for looks. When the sound waves are traveling through the pipe they bounce back and fourth against the walls of the pipe. When they get to the fluted end they move a further distance and they become louder. This silencer works on the same principle, but backwards.
NOTE: This will not work too good on a springer, but will still look cool
ANOTHER NOTE: i know that my silencer on my gun looks pretty retarded, but i got bored one day and decided to make it a rifle(im gonna add a extendable, foldable, stock, hey, another 'ible lol).

Step 1: Tools & Materials

Picture of Tools & Materials

Tools:
Hacksaw
drill (optional)
Spray paint (optional)
file (optional)

Materials:
P.V.C. pipe (optional)
any tube that fits over the cap on your BB gun and comes to a point at the end
Adhesive (preferably of high quality)
foam insulation tubing ( very thin kind, optional)
nut that fits in end of P.V.C. (optional)
cool stickers (optional)

Step 2: Prepare the Silencer

Now you need to cut off the back and the front off the silencer.
NOTE: cut enough off the front so that the BB has a little space to get through.

Step 3: Putting the Silencer On

Picture of Putting the Silencer On

Firstly, there are two different methods, one is for a permanent silencer, and one is for a removable silencer. Now, I know your thinking, "why would anyone not want a removable silencer? Well here's the catch, first of all, there's probably some retarded people out there who don't want one, and also you can only do a removable one if your tube fits very snugly.

Method one:
apply adhesive to the orange nib on the tip of your gun and push the silencer on (refer to pictures)

Method two:
simply push the tube on and pull it off when you don't want on.

Step 4: Conclusion

Bam, your done, now I know this looks pretty dumb, but that's what the next steps for.

Step 5: Pile 'O' Optionals

Picture of Pile 'O' Optionals

option 1:
put P.V.C. pipe around the silencer and paint it to make it actually look like a silencer

Option 2
Put holes around the outside of the P.V.C. with a drill like I did to make it look like a heat diffuser

Option 3
put a thin layer of foam pipe insulation around the inside of the P.V.C. to further silence the gun

Option 4
put a nut in the end of the P.V.C. like i did to make it look like its a thin barrel all the way through

Option 5
put cool dinosaur stickers on your gun to make it look cool.

Option 6
if you have access to a tap & die set you could thread the scilencer and the orange nip and meke it a screw on silencer

P.S. please comment and tell me what you think
this is my first ible', tell me what i can improve, please & thankyou

thanks for checkin' out my 'ible, and goodnight

would this work on a pvc compressed air gun?

Silencers are completely legal now without any special stamps.

Jedaiah Hungerford (author)2015-10-26

I am aware that this is an old instructable, but i need to put a warning out to everyone that might still stumble across it. This is VERY ILLEGAL. The NFA defines silencer as anything designed to reduce the report of any firearm OR COMPRESSED AIR POWERED DEVICE FIRING A PROJECTILE. The legal ramifications of this are not pretty, and it is never taken lightly in court. If you make this, and get caught, you WILL be prosecuted! No one has ever gotten away with this in the legal system. The reason it counts for both firearms and compressed air guns is that you could quite easily mount this on a real rifle. Don't make this!

All silencers will be fully legal without a tax stamp soon as they are taking off of NFA. A law just passed called the "Hearing Protection Act". Can't remember exactly when it goes into effect but it is very soon.

There is an exception i forgot to add for airgun silencers. If the silencer is PERMANENTLY attached to the airgun so that removing it would render it destroyed, then it is legal. However you have to be careful when making it. If you build the suppressor, then attach it permanently to the airgun, you have committed a felony. However, if you build the silencer while it is ON THE AIRGUN so that it is permanently attached, it is then legal. As long as a completed silencer that you are building is never off of the airgun while complete (all parts finished and ready for assembly, not necessarily constructed yet), then it is perfectly legal. Constructive intent is also illegal, meaning if you have this silencer (or any) completed (even though it is intended for an airgun) and laying around, and you also have a real firearm within your home, then it is a felony. Simply because of the fact that you could easily go slap it on your firearm.

these are not illegal on airsoft, or even on co2 guns. It is however illegal to make these for an actual firearm, or make these in such a way in which they could be used on a real gun, whether you intend it that way or not. as long as you make it so that it can't in any way be used on a real gun you're fine. Gamo makes air rifles with the silencers built into the barrel.

iperrin (author)2011-12-29

Uh... You should be really careful about where you take this. These homemade silencers are very illegal. Don't brandish it in any public place, or take it out to a friends house where people can see you from the back yard or something.

vruiz3 (author)2011-07-30

um... the real type ofsilenc3ers have an inner tube and outer tube.inner tube is the tube with the holes.the outer tube is the tube with out holes.

willij08 (author)2011-06-07

lol i used to have a pistol that i put a lot of rails on so i had a scope, foregrip, grenade launcher, stock, custom extended silencer, and i put in an m4 gbb barrel. i wish i hadnt sold it...

getfuzzy256 (author)2010-08-19

i thought that was some kind of rc airsoft robot

genius245 (author)2010-02-16

That hacksaw looks like it would make a pretty cool stock for that pistol. (With a little modding.)

superridley (author)2009-08-18

How well would it work on a spring gun?

Whaleman (author)superridley2009-09-06

That depends. Is the sound coming from the rapid expansion of compressed air escaping the confines of the barrel and into the expanses of wherever it is you're shooting it, or is it from the plunger hitting the front of your gun? Spring guns (I'm assuming that you're talking about one of those $5 spring pistols) generally don't have too much air being compressed when they are fired, so they are already pretty quiet compared to a CO2 or Green Gas powered gun. tl;dr- Probably not as well as you want.

bighead5454 (author)Whaleman2009-11-02

technically springs do use pressurized air but the sound dosent come from that it comes from the spring hitting the plastic at the end of the pressurising tube thingy

Whaleman (author)bighead54542009-11-02
I didn't say that they didn't; I just said that they used less than a CO2 powered gun.
 
builder968 (author)2009-10-24

You should probably also paint the end bright orange so that it wouldn't be illegal :O

DrWeird117 (author)2009-08-05

Oh, goody. Hopefully it'll fit in the muzzle of a 15XT.

san475 (author)2009-07-30

you put a foregrip on your pistol? thats so crazy it just might work... :)

brettcool94 (author)2009-07-10

yea well I made one and well its not the best but it does really cut down on the sound and it looks really cool. but I added cloth to the inside and some tissue and it really didn't do anything. but if you do make a silencer make sure it has 2 tubes the inner 1 has to have holes in it and don't put holes in the outer tube wrap the inner tube in tissue then cloth and insert it into the outer tube.

MerganserMan (author)2009-06-16

Dinosaur stickers! YAY! lol

Patented (author)2009-06-13

maybe if you cut the bigger end of a CO2 canister it could fit on the gun an act like a silencer

chi chi chippy (author)2009-04-08

does it improve accuracy or make it worse?

dosnt affect is as far as i can tell

Nattwood (author)2009-04-30

still looks kool tho

Nattwood (author)2009-04-30

ok im sorry to tell you but u have it the wrong way around. this may look kool but the holes have to be on the inner one and the outer one is solid or else it wont work. By putting the holes on the inside one the sound wave escape slightly into the outer section and with the foam it holds them there. i hope that this works for you.

Marble of Doom (author)2009-04-21

Silencer on my TF-11 (co2, full-auto, blow-back). Doesn't do anything for sound though, probably because of the open bolt.

CapnTac (author)2009-03-22

Genius! You have answered my hopes and prayers for an airsoft assassin pistol!

Kallen Maurer (author)2009-02-22

fallenspirit123 (author)2009-01-16

that picture of the gun with multiple attachments is plain crazy!!!

for real its got like 30 upgrades

is that picture yours or someone elses because it looks amazing (hmmmm I should try that....)

naw i just got it off the internet lol

Oh, i was about to say.....Mine!!!

airsoft_is_fun (author)2008-12-21

doesn't the bb hit the end

not if you center it right

S1L3N7 SWAT (author)2008-12-20

Trombones and trumpets are not "fluted" at the end. It's called a bell. You have the right idea, but wrong terms.

ya my music teacher told me how it all works a while ago but i couldent remember all the correct terms

Ah, no problem. I'm a huge band nerd and Trombone is one of the instruments I play, so when I saw that I freaked. I play airsoft too, I might try this for my CO2 USP, thing is way loud.
