Step 1: Get your supplies

You will need a cap gun revolver. I got this one at Albertsons for 2 bucks
You also need caps. I got a pack of 24 cap rings for a buck at Albertsons
You need airsoft bb's (of course). You can get these at wal-mart or any sporting goods store.

This is a firearm.


"any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of any explosive;"
-18 USC 921

The projectile that is expelled is the .12g plastic BB, the explosive is the cap.

Its not illegal (unless you love in NY or Cali, or IL w/o a foid card) but you need to be over 18 to even possess it.

All firearm rules apply to this.

In some states, the construction of this w/o a gunsmithing license is a felony, and ill land you in jail for more than 5 years, and remove your right to vote, own a firearm, etc.

Wow, thanks for the information. I'll be sure to put a warning up.

[Air_Assassin]

how many fps does it have

[PaulFrank]

Mine shot @ 250 fps

[Air_Assassin]

That's good

[MichelMoermans]

Frames per second? This is real life my good man ;D Unless you are getting lag while walking down the street I think the fps is really good :p Nah but I think you got your gaming words mixed up ;p

[supermack123]

dude omg its Feet Per Second no Frames duh

[Air_Assassin]

No it means feet per second man :)

[fn06afranci]

feet per second, its what bb guns are measured in

[MichelMoermans]

:p I'm sorry, as a European I was not familiar with your system of measurements ;)

[mechaninja]

I'm pretty sure FPS is metric.

[LiquidLightning]

Facepalm. FEET per second. Feet are most definately not metric. Metric is meters.

[mechaninja]

oh wow lol im a stupid person feet are american standard! lolwut i should know that

[chocowubbles]

Well I dont have a chronometer, so I cant measure, but its not a lot

[vince andrew]

how fast can the bb's shoot.by how many feet per sec

[PaulFrank]

250 fps

[~Aeronous~]

hey, I just notiiced but its not an airsoft gun, its powered by gunpowder.

[PaulFrank]

you think

[Hitman227]

It would most likely be considered an airsoft gun becuse now they have newer
hybrid cap powerd airsoft guns with shells. ( what I mean is cap goes in the
back of the shell and the bb in the front.)

[chocowubbles]

Well, gunpowder still fires by using gas generated by a small explosion, so in a way, it is. But you are correct in that it is not a true airsoft gun.

[Hitman227]

It depands on the standerds for a 'true airsoft gun'.

[sharlston]

it also not gunpowder its the stff they use on matchheads

[Hitman227]

I agree its not pure gun powder. You wiil notice when you hit a stryke anywere
match with a hammer on a flat surface it will explode.

[zimmemic25]

it is an airsoft gun. because it uses air pressure to fire the BBs. the fact that the air pressure is generated by an explosion doesn't say it's no air pressure. there are airsoft guns powered by methane too, thats also pressure by explosion.

[LiquidLightning]

Not methane, propane. And they just use the pressure of the gas, they do not combust it.

[aseaheru]

co2 as well

[darman12]

Do you put the BBs closer to the caps or the end of the cylinder?

[darman12]

I assume closer to the caps but i'm just making sure...great instructable by the way!

[DouglasG1]

I don't know about you, but i like this gun. Try the same with other cap guns.

[Dr Qui]

I can remember a commercial version of this being available in the UK for all of about 2 months back around 1982-4, they where a Chinese import that fired small hard rubber bullets powered by caps.

I took less than 6 weeks before before more than one idiot lost an eye and they got banned completely, there was even a nationwide news alert not to buy the toy and the police seized any remaining stock from shops and market traders.

[highvoltageguy]

This would be classified as a real revolver because it uses explosives to fire so be careful. OK

[jbend]

How far dose it go

[Timatobut]

Pretty good. It is technically a real "gun", and can get you arrested. It just fires custom projectiles.

[sswartz2]

arent there plastic things that sit behind the cap? inbox me the answer please. :)

[ilpug]

Dammit, i am driven to make a better version of one of these. like one that could be used in an airsoft game with actual tactical applicability.

[ilpug]

I would have to see that chrono'd to believe it.

[2hot2hack]

can you use ordinary metal BBs ornot? cos in australia we cant get airsoft.

[sanagol]

it wont fit in the revolver because a metal bb is 4,5 mm and a plastic is 6mm

[2hot2hack]

so wat if i find a metal bb thats 6mm not 4.5??
