from Perjak but this is different by quite a bit. In this you sacrifice your gun for a stronger airsoft gun. And I am sorry perjak because i did kinda steal just the pen or straw sticking out.
Step 1: Materials
All you need is your gun
A screwdriver (to get the head off)
Airsoft pellets or bbs
a strong straw
a mechanical pencil
a LOT of tape
perhaps a rubber band for the more auto-loady less dependable peice
Step 2: Remove unnessasary items
Step 3: Create your new barrel.
Optional: make yourself a little "bb door" from a tiny peice of another straw and tape that to the side of the barrel so it holds the bb in a tank thing better and you can aim anywhere.
