Follow along on this fun weekend project as we build a CO2 Cartridge Rifle. Only rather than being powered by the CO2 Cannister, this one uses the cartridge as the ammunition!!!
I spend a lot of time shooting my Umarex Walther CP99 CO2 BB Pistol in my back yard. I've always got a pile of these empty CO2 canisters laying around, and that gave me an idea. Let's turn those into projectiles! Recycle them into ammunitions. Amazingly, they work extremely well!
Why all the fuss about 3D printed guns? Who needs a 3D printed gun when you can build one at the hardware store in 20 minutes? No background check required.
