Yeah I've grown up around guns my whole life. We definitely consider it a weapon. It stays in the garage and the ignitor is up on a ledge. We have alot of friends with younger kids and if they want to try it we hold the gun and they just hit the little red button.

My next project will be with hpa ...

I've seen the same type of stuff misconceptions come up on my car forums but I was on here an hour or two looking through stuff and never came across there being diff ...

Yeah everywhere I looked it just said use schedule 40. It's already glued. My brother asked about it but the guy said its schedule 40. I was under the assumption its the same stuff but I've been sitting here at work wondering so I wanted to ask.

Definitely handheld/shoulder fired. Mortar is just too big. I have a 2dr coupe and i'd like to be able to toss it in the car with a seat reclined and not have much trouble transporting it. Budget wise...if it worked good I'd say $100 to $150 bucks. I'd rather keep it lower but if its gonna be 150+ i ...

I was searching for a bit today but everything kept going to airsoft guns etc. I want to build a potato gun...nothing super fancy. But i have a multitude of HPA tanks from my paintball guns. They are steel tanks at 3k psi and i believe ...
