Homemade Air-Rifle

Guard your stuff with this cheap, high-powered homemade air gun

DISCLAIMER: MAKE NO MISTAKE, THIS IS A WEAPON. DO NOT SHOOT AT ANYTHING FRAGIAL OR ANYONE. IF ANY PROBLEM OR DESTRUCTION IS CAUSED BY THIS, I CLAIM NO RESPONSIBILITY.

Step 1 Materials

What you will need:

-Approximately 1.25 meters (4 feet) of 1/2 inch PVC pipe - you probably won't need that much but keep it just in case you mess up on a step.
-A 591 mL soft-drink bottle like what you normally drink coke out of
-A small sports pump
-PVC fittings (all 1/2 inch): 1 ball valve, 1 "T" shaped fitting and 3 elbows
-Hack saw and serrated steak knife
-Hot glue gun
-PVC bonding glue (optional)
-Creativity(!)

I got all my PVC and fittings from a lumber store, not a hardware store. They only sell in 10 foot lengths so it cost me around 7 dollars (Canadian).

duct tape is a holy substance

[werd123]

Duct tape fixes everything... not necisarily well but it fixes.

[juvenilej1]

electrical tape followed by duct tape extra holy :)

[_Scratch_]

yes it is, duct tape solves all problems... lol

[tigerdog10]

i agree duct tape all the way

[hazza the gun]

yea XD roflmaool

[mitch and sean]

Is it halve inch inside the pipe or outside diametre

Pls get back to me

[dog digger]

Outside diameter

[mitch and sean]

Instead of cutting the PVC with a hack saw and stuff can I just use my pipe cutter?

[35Timmy]

well there is one thing you should add to it and that is instead of using duck tape you should use threaded plumbling parts which will be more better than duck tape other than that everything is perfect

[35Timmy]

it's better to use a threaded plumbling parts then using duck tape,adhesive, or pvp cement even combined it's easyer to use threaded valves and alot safer than posions that could pollute and besides threaded parts are more air tight and way less chances of leaks then using glue,duck tape and pvc cement which could get a hole or fade off

[35Timmy]

What's the max feet per second and max muzzle energy?

[35Timmy]

You used a 2 litter bottle and you said a 591 milmeter bottle however I guess ether is good to use

[Delo97]

Couldn't you put some "square comment things mousey" and write on which piece is which? It's a bit confusing...

[lpletikosic]

where I can find instructable for your sniper rifle

[shubhamrox]

does dis really shoot wid da sports pump???????????????????i tried it and ot is all cmmin rong

[hazza the gun]

what? english, please 0.o

[Hitman227]

C+ is awsome.

[skimmo]

if using the coke bottle is going to cause issues cant you just use a larger conduit and a adapter?

[brianthestud]

can you fit nerf streamline darts into the barrel and make it fly fast

[toogers]

if you use half-inch pipe, then they'll fly with enough pressure. don't expect accuracy though

[count jamez]

Depends on the size of the barrel. Don't pump it up to much though, or it will destroy the dart.

[jchan_98]

when i connect the pipe into the bottle (coke) should i put it all the way through? or just a bit?

[jchan_98]

would hot glue work for attaching the bottle to the pipe?

[jchan_98]

could u use electrical tape to cover the leaks? and also. how long does each of the pvc pipes need to be?

[H20]

don't use t he bottle

[h3x_your_nightmare]

use some pvc cement or some rezin for covering the leaks ;) duct tape doesn't solve the problem for a long period of time ;) peace!

[nutsandbolts_64]

From my experience, duct tape doesn't seal the deal. I use epoxy (because I've got no silicone sealant (of which I don't know if it works)). And instead of the ring sight, use the sights that are used on grenade launchers. That gives accurate targeting at far ranges.

[VersatileHobbies]

nice design im gonna build 1 this weekend =)

[blugyblug]

MrCrowley said that you shouldnt use PVC Cement on PVC to Coke bottles, so what do u use? super glue? Epoxy?

[rhino132456]

you can use pvc cement on bottles

[yourworstnightmare]

no use duct tape there but use pvc cement and primer everywere else

[MrCrowley]

You're using PVC cement on PTFE. You sir, are a genius.

Goodluck with that, by the way.

[blugyblug]

Whoa whoa, how old was this post? Its been more than a year and rhino commented..? I already know rhino..

[rhino132456]

You don`t know me. I live in minnisota.

[blugyblug]

No i mean "I already know that you cant use PVC cement on bottles"

[rhino132456]

that message was for mrcowley

[rhino132456]

I already done it. smart one.

[zach12]

forget him pvc cement works perfectly for me without any leaks

[Rishnai]

Ask for a glue that will bond PVC to PET. If you can't find one, you could try superglue and liberal amounts of tape. Or you could use a PVC chamber. It's your gun.
