This actually works!!! Only for the Crossman c11 airsoft gun though. When the C02, as well as the BB is shot through the barrel the excess gas is absorbed in the silencer reducing the sound and making it sound much cooler.

Step 1: Materials

What You Will Need

Spray paint (any color)
60ml bottle
Toilet Paper
Toilet Paper Roll
4'' Long hollow plastic or metal tube (must be able to fit snug into the neck of the bottle)
13/64'' drill bit
5/8'' drill bit
Small skiny object like a pen cartridge or a dowel

Step 2: Cutting and Measuring

First take the 5/8'' drill bit and drill a hole in the bottom of the bottle. (make sure the hole is exactly in the middle) Once completed take the plastic or metal tube and push it through the bottom first all the way to the neck. It should not be able to go all the way through. Make sure to leave about a 5/16''  gap from the end of the tube to the top of the bottle. (as shown below) Next mark with a pencil exactly where the tube comes out from the bottom of the bottle. Once you have your mark cut it with a bandsaw. Insert the tube again into the bottle. Make sure the tube is flush with the bottom of the bottle while still maintaining the space at the top. If everything lines up take the 13/64 drill bit and drill three holes in a row in the plastic or metal tube.

Step 3: Filling the Silencer

Now cut your toilet paper tube right down the middle. Measure how long the bottle is not including the length of the neck. Once measure (mine is 2_1/2'') cut the exact length of the bottle on the toilet paper tube. Once finished roll the tube up as tight as you can. Remember it has to fit inside the bottle. Once inside the bottle take your metal or plastic tube and push it in the bottle making sure is goes in the middle of the toilet paper tube. Only push the tube 1/2 way in. Make sure the toilet paper tube is pushed to the sides of the bottle. Next take small pieces of toilet paper and start shoving them inside the bottle., Make sure it goes around the plastic tubing. Keep doing this until the toilet paper is packed fairly tight. Then push the plastic tube the rest of the way in. Remember to keep a 5/16'' gap between the end of the tube and the top of the bottles neck.

Step 4: Finishing Touches

Now that your silencer is complete. Theres one more thing to do. Painting it. If you choose not to do this it does not affect the silencer in anyway. I perferred to use black hence the color of the gun but its all personel choice. Once finshed just slide it on your gun. Theres no twisting involved with this silencer like some other guns. Now you are finished with your silencer. Have fun, and enjoy.
<p>The question I ask is what's the best pistol to use this with out of these</p><p>http://airsoftaid.com/the-best-airsoft-pistols-for-2016/</p>
Yeah....this don't work. Smh.
This would be cool, if it wasn'r ILLEGAL!!! (Home made silencers are illegal, look it up!)
for airsoft IT IS LEAGAL in america anyways......
*wasn't <br>I didn't mean to hate on your project. Its cool and all, but I felt that other users needed a fair warning.
100% correct. Registered silencers are legal in some States. Some States have made all silencers illegal. A homehade silencer, though a toy, is still legally classified as a.silencer. penalties can be up to 10 years in federeal prison, as no distinction is made between toy and real, as if the silenced reduces the sound at all, it is considered a real silenced, and the maker can suffer fill legal consequences if caught. Use common sense when using airworthiness guns, though a toy, they are very realistic, do not ever paint over theorange cap to make the gun &quot;cooler&quot;, that is also a felony. Above all, most kids nowadays with airworthiness arenot.mature enough and do very stupid things, which then get posted to youtube where law enforcement can track people down for unsafe or illegal. BEhavior.use common sense people, guns aren't toys, even if they aren't lethal
Isn't this for airsoft?
i kno rite?
IDK where you live but in wisconsin this is LEGAL! The following link apllies to both real firearms as well as fake ones like airsoft. Besides, it cant be illegal since most of the sites that sell airsoft guns sell silencers as well. I could understand your point if this was a real silencer to silence a REAL fire arm. But even then were I live this is LEGAL. http://answers.yahoo.com/question/index?qid=20071026063433AAszfQV
Now wait, I didn't say having a registered silencer was illegal, but a home made silencer is a different story. I'm pretty sure HOME MADE silencers are illegal. But then again, it's not a real gun.
Homemade silencers are legal as long as they are registered.<br>And airsoft silencers... no one's going to care as long as you aren't walking around outside in public with it
Does anybody really care if they are or aren't? It's not like you would be showing off your awesome firearms off to a cop anytime soon, that's like asking to get shot
Just like in Shooter (2007)
this is cool im posting this comment because i should be studying for a science test but im looking at airsoft on instructables.&nbsp; Also this is really cool its the first airsoft silencer on here that actually works overall great instructable and idea. 5 stars
