This is a homemade grenade launcher for your airsoft guns. It has an inner high pressure chamber. This launcher uses 12g Co2 cartidges to pressurize the chamber. You can either glue the shell down or make an interchangeable system. ALWAYS refer yourself to the images. A picture is worth a thousand words!!! ;)Video demonstration
Step 1: Materials
For this instructables you will need the following materials:
-2 piece of 1.5 inch abs pipe (1 feet long each)
-2 1.5" coupler
-2 1/2" metal ball valve
-2 1/2" nipple
-2 3/4" to 1/2 reducer

-1 Dollarama spring party popper
-2 electrical wire cap
-1 toillet or sink pipe (refer to picture) 20" long
-Hot glue gun
-Dremel with sanding disk
First, you will need to assemble the pieces like so.
Step 2: Grenade launcher shell
Disassemble the dollarama party popper and keep only the tube. You need to remove the bumps and line inside the tube. Mesure 8 lenght of toillet or sink pipe, cut them then glue them with the hot glue gun. Glue an electrical cap in the center at each end. Make a little lip so that the bbs don't fall in the launcher on one side of the shell.
Step 3: Plumbing
You need to assemble the plumbing parts in this configuration. ADD A LOT OF TEFLON! In the bottm of the 3/4" cap, glue the thumb tac with the hot glue gun. BE SURE IT IS CENTERED.
Step 4: Moding the ball valve handles
Take the wrench and remove the handles on the bal valves. Then unfold the legs on the handles and screw them back in.DO BOTH.
