Make a Silencer in Under 5 Minutes





Introduction: Make a Silencer in Under 5 Minutes

About: Eh, I'm just a goofy guy that loves technology and random stuff... you might notice that by my awesome instructable

Make a simple silencer fast with common materials

note: silencers are most likely prohibited in your area without a special license. Check your local laws before attempting this. Also, this instructable is purely for informational purposes and could be dangerous and prohibited.

Step 1: Locate Your Materials

First, let me paint the scene for you:

In a post apocalyptic world, you are shopping in a supermarket with your high-powered sniper rifle slung across your shoulder. All of the sudden, alien invaders burst into the supermarket. You notice that the head honcho alien who's brain serves as a central brainwave server is among the intruders.
Seeing as how the aliens havn't seen you yet, you quickly devise a plan.
You grab the items from your cart and jump on top of the freezer isle behind the igloo coolers.
Your plan is to take out the honcho alien without revealing your position. Since your not super creative, you don't think of anything clever aside from shooting him. So! you need a silencer.

Among your grocery items you happen to have a newspaper, a 2 litre bottle of soda, and some electrical tape. Good! thats all you'll need... plus your trusty sniper rifle.

Step 2: Prep Your Materials

Thinking quickly, you dump the contents of the soda bottle and begin to roll up the newspaper pages. You stuff them into the soda bottle until you can't fit any more.

Then you wrap the barrel of your rifle with electrical tape until the mouth of the bottle will fit snugly onto the barrel. You secure the silencer onto the barrel with some more electrical tape and peer from your perch in order to locate the aliens positions.

Step 3: Take the Shot Then Admire Your Work

Spotting the head honcho alien in the self checkout lane, your take aim.

As you exhale your finger eases onto the trigger. A muffled "pop" sound eminates from your barrel. BUT because your silencer screwed up the trajectory of the bullet, it misses the target. It ricochets off the hardheaded store manager and strikes the alien anyhow.

Mission Accomplished. The other aliens flee the scene, the town, earth in it's entirety, and you can sit back and enjoy a brewsky.

Once again, I must warn you. This really isn't a good idea to do in real life due to it's danger and legality, but it's good info to know for a post apocalyptic world.

    i was going to make a instructable for something like this :(

    VERRRRRY ILLEGAL Be careful I think this is a felony.

    ONE WORD : AIRSOFT!!!!!!!!!!!

    Still illegal, still suppresses a blast from a firearm.

    no its not illegal to build or have a flash suppressors as long as your register it with the ATF

    Actually, many states allow suppressors. Trying to find a manufacturer of them that sells to FFL holders who sell to private citizens is hard, and finding an FFL dealer to sell you one is much more difficult.

    He can build one himself (provided his state allows them), but he still has to pay the $200 to ATF and wait for his Form 4 with tax stamp. Without a tax stamp *in hand*, one would be VERY foolish to attempt this on a real firearm.

    Did you even research the law before posting your comment? Try it. P.S. Don't crash!!!

    It's only illegal if you haven't payed $200 to the ATF for a silencer and gotten an OK.

    *Choose a long thin bottle with a neck opening slightly larger than the barrel of your weapon.
    *Cut a hole in the base of the bottle abour 1/2 and inch bigger than the neck.
    *Insert pvc pipe the size of the neck opening and the length of the bottle.
    *In the space between the pipe and the edge of the hole (in the base) insert wire *wool.
    *Pack it tight.
    *Remove the PVC pipe.
    *Attach to barrel.

    This i pretty good. I prefer a suppressor made from pvc. For ammo, i would recommend Remington Sub-sonic, these can be bought at various gun stores, like gander mtn., ect.

    Hi :
    I have made some suppressors, and suppressed pistols & rifles, .22 to 9mm.
    The Tim Le France design of 3 1/2 spherical chambers is very efficient. If I did not have a "Ball end mill " of the appropriate size, I used a standard drill bit, with satisfactory results. Here in New Zealand, there are no leagal restrictions on suppressors, possession, or use. No longer shooting, previously had quite a few suppressed firearms. Cheers,

    this is not gonna work un less u have 4 inch riser scope mounts and ur using a airgun this wont work on real guns

    Is that a real rifle?

    The soda bottle suppressor only works with small caliber guns ( .22 lr ). Even with a silencer you would still need subsonic ammo to eliminate the sound that the bullet makes when it passes the sound barrier. I think you need a hole in the end of it too. =)

    Here is a vid of a soda bottle suppressor that works.

    Dacron sleeping bag filler would work for a silencer: nonflammable and durable. Of course the resistance to force would preclude it from use in the guide's silencer and more towards a reusable pvc-and-bottle silencer where the dampener is seperate.

    what about using tenes balls still in the bottle

    What you should do is get a piece of tube to fit around the barrel. Use a drill and cut several holes into it. Next, take your bottle and fill it with steel wool. It is a much better and safer dampener than cotton balls. Then fit the bottle around the tube. Cut a hole in the bottom of the bottle so the tube can protrude slightly through it. Now what you should have is a cheap working silencer. The holes in the tube should allow the gas and pressure from the shot to escape outward into the steel wool which should dampen the sound.
