nerf guns

[quinn whitsitt]

i have a qustion to ask
how to create a nerf rivial gun that i semi auto and is a sniper that runs on very high pressure you can use air or co2
one other option is that you can use a after barrel co2 or air compressed to shoot gas out of the barrel and into the air and have a ligher on the front that way it whould detonate at the very edge and shoot it out like a sabot
