Hi this silentassasin21 presenting to you I_Am_Canadians Battle Rifle. This gun is way better by far then anything i've created. It shoots 40feet with two of my rubber bands. I've moded it a little so it has a Grenade Laucher and its own handle the grenade laucher is Katarukito's.

So with out further ado here are the instructions

Step 1: Body

Step 2: Trigger, Receiver, Firing Pin and Pin Guide

Step 3: Sight

Step 4: Hopper

Step 5: Pulley Cover

Step 6: Grenade Laucher

I have no instructions for the grenade laucher but its very simple to make. The Handle is also easy.
