This is a pen that looks completly normal and it shoots airsoft bbs and other stuff.(not responsible for injurys).
Step 1: Tools
1 needle nose pliers
2 sand paper
Step 2: Pieces
to bic pens, and two springs from click pens.
Step 3: Take apart the pen
Take apart both bic pens and get this piece out
Step 4: Sand the pieces
sand the pieses one on the back and one all around.
Step 5: Check your work
the piece that u sanded all around should look like this. I wraped a little piece of paper around it so it would fit in the pen tight.
Step 6: Put it together
it should look like this, after you put everything on use the needle nose pliers and flaten the end opposite of the tip, so the spring wont come off the pen.
Step 7: Put it in the pen case
put th whole thing in the pen case.
Step 8: How to shoot
make shure the cap on the back side is off, and then put an airsoft bb in on that side and take the fron part out till it stops, and then realse the airsoft bb should go flying.
