How to make a Knex Pistol

First off, I'd like to give credit to Killer~Safe~Cracker and Alien Terminator because this gun is based off the TBOS,TBAP, and the Oodammo Assualt Rifle. I also put their names in the video in the credit section. On to the stats.
Range: 50 feet with 2 #64
Accuracy: Pretty accurate because it's an oodammo pistol
Reliability: Ok I admit the trigger STINKS! But you can easily modify it.
Comfort: Out of 5, I'd give it a 4* because It's pretty comfortable, but you can cut the rods on the handle for more comfort.
