Introduction: Nerf Gun Hack Airsoft

This nerf gun hack makes a switch shot EX3 into an AWESOME airsoft gun. This is an extremely easy hack which requires absolutely NO MODDING (to the gun) WHATSOEVER!!! And as far as I'm concerned this is the first EX3 mod.
Both barrel parts aren't mine and credits go to whoever made them. 
Oh and I have no idea what the fps is sorry.
Constructive criticism welcome.

First instructable please be nice.

Step 1: Materials

You only need 3 things for this mod:

a dismantled BIC pen tube
a nerf dart minus the velcro, plunger, whistle, etc.
a nerf switch shot EX3 (will probably work with any front-loaded gun)
and a pair of needle nose pliers

Step 2: Barrel

The barrel is the hardest part of this mod but it is fairly easy.

Just pit the pen into the nerf dart, and leave a little bit of the pen sticking out the side you put into the gun.
Crimp the top a little with the pliers so the bullet doesn't fall out

Step 3: Insert Barrel and Your DONE!!!

Just put the barrel piece into the nerf gun's barrel and your ready to shoot

DISCLAIMER
I AM NOT RESPONSIBLE FOR ANYTHING STUPID YOU DO WITH THIS. ANY INJURIES CAUSED WHILE USING THIS GUN ARE NOT MY PROBLEM. My word of advice..... DONT SHOOT YOUR EYES OUT!!!!! WEAR EYE PROTECTION!!
