Testing of firing system outside. Currently the system is fired using a hammer to strike the firing pin to puncture the CO2 canister, but that will be replaced with a spring powered hammer in the near future. It is hard to tell in the video, but we were playing with different levels of friction to hold the canister in place for the puncture to occur. This allowed for a more solid puncture which in turn allowed for a more rapid release. Future modifications will include mounting the loading tube, replacing the barrel with tighter tolerances, and adding a hammer, stock, lever action, and trigger.
Sorry for the vertical video :)
