Homemade 500 Fps CO2 Airsoft Gun

 In this instructable I will show you how to make a 500 fps CO2 single shot airsoft gun.
I think putting this magazine on this would work good. www.instructables.com/id/Semi-auto-pen-airsoft-gun-w-mag/

I take no liability for what you do with this.  This is very powerful and would go through human skin.  This instructable is for informational use only.

 You will need
1. A co2 bike tire inflator that has a valve so it doesn't let the co2 out when you screw the top on like some
2. A bic pen
3. Co2 for the inflator
4. Airsoft BBs
5. Electrical tape
you can buy a co2 bike inflator here

 To make the barrel, take the pen apart so you have just an empty tube.  This will be your barrel.

 Now you want to tape the pen to the opening of the tire inflator.

 To fire you will put a bb in the barrel and hit the valve with your palm quickly.
