Introduction: Airsoft Silencer

Picture of Airsoft Silencer

Give a general description of the Instructableis my homemade beretta 92 fs spring airsoft silencer. I would say that the total reduction is something like 30%-40%.

Step 1: Materials

You will need the following materials and tools to complete this project.

a length of 1 inch or bigger diameter thin-wall pvc pipe
1x mini (12 oz) gatorade cap
1x 2L coke bottle cap
1x expo dry erase marker
a bit of pipe insulation
epoxy or some other wicked strong glue

a rounded file
a flat file
hack saw
clamp(useful for holding stuf togeather while drying and holding stuff while sawing it in half)

Step 2: Finding the Right Pipe

I found that a 1 inch diameter thin-wall pvc pipe worked fine with this gun. I would recoment that you don't make the silencer longer than the gun itself.

Step 3: Finding the Right Size End Cap.

I found that a mini Gatorade bottle cap and a 2L coke bottle cap fit perfectly. Fust put the coke cap inside the Gatorade cap and glue them together. I used a five minute epoxy to securely hold them together. You want a very strong glue for this part. Anything less will cause the cap to fail in later steps.

Step 4: Finding an Adpter for the Muzzle of the Gun.

I found that the orange tip had a diameter of roughly 5/8 inches. I searched around my house and found that an expo dry erase marker had the perfect diameter. I pulled out the back with a pair of needle-nose pliers. I pulled out the ink foam thing and then pulled the felt tip out of the front. I then cut the marker tip off so I had a small 5/8 inch diameter tube. i used my hacksaw to cut the tube. it's stiffer than it looks.

Step 5: Fitting the Adapter to the Caps

I drilled a 5/8inch hole into the caps but found that the hole wasn't big enough for the expo marker so i filed it into a rough circle untill it fit VERY TIGHTLY ONTO THE EXPO MARKER. This is very important because otherwise you will beed to glue this as well.

Step 6: Finding the Right Silencing Material

I used a piece of pipe insulatiion for my silencing material. i had to cut it down a little, but it fit in the end. try to make a hole about 1/2 inches in diameter tough the middle of the silencer so there is room for the bb to fly.

Step 7: Final Assembly

This sept is very easy. Simply slide the assembled expo marker and caps into the pvc pipe and pipe insulator. if you want to glue the cap and marker to the pipe, go right ahead. I didn't to allow for future modifications and for easy replacement of parts.

does this actually work?

Ericharstad (author)2016-09-07

Alanshkop, a real surpressor wouldn't block the iornsights, but airsoft surpressors block the iornsights...........

nktish1 (author)Ericharstad2016-09-11

This isn't true, there are specific sights made for using larger cans. Know the facts

Alanshkop (author)2015-03-22

No offense but if you look at a real surpressor it does not block the sights but still it looks awesome

austin1201 (author)2008-10-02

when I was building 1 and cut my self and had to get stitches

pandaboy292 (author)austin12012008-11-03

where did you cut yourself? once i was cutting a pop can with a razor blade and cut my left index finger. it was on the tip, and after about five mineutes it was throbing alot. this was all the night before i flew to flordia. oh boy salt water in a cut is fun.

I cut my middle finger off before ?

austin1201 (author)pandaboy2922008-11-04

i cut it on my left index finger right were u bend it

garrett10 (author)austin12012009-01-10

now way! i was cutting bamboo with a knife and i had my hand under it and i cut it right on the joint.

tictaclad (author)garrett102011-01-24

one time i was prying something with my knife (i know bad idea) and it folded in on me and i put tissue on and taped it really tight and in the morning it still hadnt stopped bleeding lol

Gawane88 (author)tictaclad2011-06-22

no way! I was cuting some cardboard with my leathermen and the knife blade
slipped and it sliced one of my joints on my finger and now I'm scarred there.and I'm only 9! i have more scars than my mom!

I wonder how this works with NBB airsoft guns. I think the KJW MK1 Would be a very nice place to start.

glarive (author)2013-08-17

That's a hella project looks great, a nice coat of black paint and your set!

coolkidtn (author)2012-12-10

Yes the P311 rocks. I was in an airsoft war, and charged 2 guys. One had a shotgun and the other had an AEG. When I held up my pistol, they ran away. (They ran away because I kept pelting them in the back)

linuxkid (author)2012-07-15

You realize this is illegal unless you pay the nfa taxes, right? even having the stuff to make one, along with the intent, and not paying the tax will land you in jail for quite some time. even if it is only airsoft.

runthunter246 (author)2009-04-03

what kind of airsoft gun is that???spring or gas or electric?

ilpug (author)runthunter2462011-09-27

It is a spring gun. My favorite "cheap" spring pistol is the Smith and Wesson 1911 from Walmart. 300 fps, 15 round mag, very durable. Super accurate.

h8864 (author)ilpug2011-12-25

mine is a stinger p311 it was $20 and is 325 fps.

ilpug (author)h88642011-12-25

Yeah, I just got a HK USP CO2 pistol from Umarex. It is seriously badass.

h8864 (author)ilpug2012-06-09

not as badass as my new r71 repeater.

mrwaffles2 (author)h88642012-01-28

I love stinger p311's i bought two in a challenge kit and so far they are a very good sidearm.

superbestknex (author)ilpug2012-01-17

crossman stinger p311

asghdf (author)superbestknex2012-04-23

well warrior L96 bolt action is the best

superbestknex (author)asghdf2012-04-24

more expensive the guns were talking about are less than 50 dollars

asghdf (author)superbestknex2012-04-23

well warrior L96 bolt action is the best

says "beretta 92 fs spring" at the top of the page

sharlston (author)Marble of Doom2009-06-11

how much was it? i got a 190 fps spring for $14

th3gamingkid (author)sharlston2012-02-28

i got a 325 fps spring for 15$ at BIG 5 at X-Mas. :)
its a Desert Brown Camo. Really Good reliable gun.

nerfer192 (author)sharlston2009-07-08

was it a taurus millenieum? mines 180 fps and $15. great gun

I got s 315fps spring pistol for 20$

sharlston (author)nerfer1922009-07-09

no its the p329

Lowney (author)sharlston2010-01-03

What? I got a p329 for £4.90 as a garden thing (apprently my gas pistol is too powerful for plinking around). £4.90 is about $7 I think

sharlston (author)Lowney2010-01-04

i bought 2 for 10 pound

Lowney (author)sharlston2010-01-04

I thought you said it was $14

sharlston (author)Lowney2010-01-04

on its own it was 7 pound but i bought two for ten pound

nerfer192 (author)sharlston2009-08-09

or a p230? my neighbors getting that one, yay! now we can have fights!

Marble of Doom (author)sharlston2009-06-11

I wouldn't know, it's not my gun nor instructable

omg i now somone with that but the seetrough version

h8864 (author)2012-03-18

if you load more than one to fire it has a *SHOTGUN* effect

superbestknex (author)h88642012-03-20

yeah it does

halogirl (author)2010-08-06

spring pistols are dum get a gbb pistol

ilpug (author)halogirl2011-09-27

Hey, quit hating. Springers are tons of fun, and surprisingly effective if used well.

halogirl (author)ilpug2011-10-03

im not hating my first gun was a $20 beretta 92 springer it was fun until i got my all metal gas blow back beretta 92 and then i saw how dum it was

ilpug (author)halogirl2011-10-03

dont say you aren't hating when you are. good day sir.

dla888 (author)2009-09-19

A real silencer works by allowing the gases emitted from a gun to cool and expand. By packing this silencer with silencing material you are defeating the purpose. The gas that comes out of your aifsoft gun can't expand(decompress) as much as if it were not packed. What I'm getting at is if I were making this I would not use the silencing material. Otherwise it's a great instructable. Much better than the paper one's I make.
