How to Make a Flash Suppresor/silencer for an Airsoft Gun




make a flash suppresor/silencer for our airsoft gun using the venturis from a gas grill burner assembly!!
it gives the opposite team a scare when you first pull your gun
out! why waste time on ebay searching for cool silencers when you can use your old not so handy dandy venturis!!

this is my first instructable,so HIT ME WITH YOUR BEST SHOT!!

if you have a bad comment regarding the instructable, BRING IT!!
if its good, much apprediated.

*NOTICE FINE PRINT* if you comment me, i will comment one of your instructables in the same fashion as you did mine.



Step 1: Gather the Materials!!

2-pen, pencil, something to fit inside barrel
3-Venturis( i think that's what its called)
4-electrical tape
5-the most important piece, the gun

my dad sat on my gun while it was on my bed and broke the barrel
so, this proves that nessecity is the mother of all creations

(Mother nessecity, where would we be? plays in background)

Step 2: Grab the Venturis

alright, grab the venturis and look for an ideal spot to cut it seperate from the bend

on mine, its about on the edg of the wood thing

Step 3: Hack Away, Hackers!!

grab your deadly hacksaw and hack away at the spot you've chosen!
it help if you do what i did and put it on the edge of something and put your fott on it

Step 4: Clean It!

grab the now shorter venturis and the pencil and/or item of your choice and slide the pencil in the venturis.
now start to scrape the inside with in/out/circle motions
(freakin perverts, might as well stick the pencil in your head to clean it out. :p lol, j/k)

this step is to remove the rust or debris inside

Step 5: Fit It!

now, stick the now semi- clean venturis on the gun barrel.
if its bigger than the guns barrel read on.
if its just the right size, finito!, your finished.

if its bigger, you will need a male/female hose connector.
the male part of the hose connector should be small enough to hug the barrel.

the second picture shows the male/female connector.
i'll go over this step next

Step 6: Adjust It Firmly!!

if it didn't fit, you need a male/female hose connector as show in the previous picture.

apply electrical tape GRADUALLY to the venturis, this means
put a little on then check if it fits snugly in the female part(of the connector, pervs)

then slide the male part into the barrel of the gun, put some tape on the male to ensure a snug fit

Step 7: Slide It In!

there you have it!!
just slide it in or off
try using sand paper to give the suppresor a war-torn look.
and try spray painting the hose connector, mine's pink, but im gonna spray it.

gratzi. im not italian, im hispanic, but i like other languages.
and guns

    so... does this do anything? why call it a flash hider if there is no flash to hide?

    I just got some styrofoam tubing i think my dad used it to insulate pipes in the winter. Cut it to about 6 inches and wrapped it nicely in electrical tape. It slides over the barrel of just about every gun and covers up the orange tip without taping it (can slide it off if cops or people are nearby). It does change the sound of the gun whether it's quieter or not i can't tell but it looks cool and camos the orange tip.

    I dont understand why airsoft players think they need silencers, the gun is silent already. My friend has 2 and we shoot eachother all the time with them, and its not like a pipe on the end is going to effect the sound of the spring because no matter how long the pipe or how many holes in it, the spring is still going to dislodge making a noticeable sound. is it just for looks?

    This one is. Others, like the one I own, are to stabilize my barrel, I have a 498mm external barrel, but a 520mm internal barrel, and I need something to hold the extra length in place, and protect it from getting banged around.


    Reply 8 years ago on Introduction're aware that more than one company makes the same gun...The only guns that are company-specific are ones that the company creates themselves, like the F-Chu speedracer, or the PSS-300. You can get this gun for $50 at walmart, or you can get it for $500 from a company like, or Although granted THIS exact one is a $50 version, you can tell by the fact that a.) it's spring. and b.) The rails split down the middle, no good rails will split down the middle for obvious reasons. Again, this is not the gun you're talking about, as it's spring it has no full-auto feature, it's as practical as a bolt action.

    Wrong, they're not pointless. They look cool, and if you're like me, then you need a barrel extension. I've got a 498mm outer barrel, but a 520mm internal barrel, I need something to hold the extra 22mm in place, and protect it.

    Airsoft flash supressor? I dont think they make a flash. Okay. When a gun is fired, what you hear is two different overlapping sounds. The first one is the actual crack from the gun powder exploding, forcing the bullet to leave the gun. The second sound is actually from the bullet leaving the gun, breaking the sound barrier. So its sort of like a super sonic crack. But as we al know, airsoft does not use real bullets (that means no sound or flash) and the pellets do not travle fast enough to make a super sonic boom. So that means that airsoft suppressors are pointless :D
