This is something a little bit different, note the extra barrels, utilizing the valve exhaust for a smaller calibre projectile.

1. The metal tank is the air camber.
2. Yes it is modded, thats what the ball valve is for and thats wh there is no solinoid.

Nice cannon though, ive never seen someone not use a sprinkler valve to hole chamber pressure on one side and barrel on the other.

The sprinkler valve is a pilot valve for a piston or a diaphragm.

and that vented air is also routed to a second barrel, making it sort of a hand held double barrel. it took me a second to look at all the pics and make sense of it cause its made of spare parts, hence the name junkyard dog haha. The design is pretty cool, i like the ingenuity. i bet that mcguyver guy made it

i wonder how the exhaust barrel performs, that's an awesome idea!

it'd be cool to see this thing shoot ammo tied together.

it'd be like one of those weapons on the kung-fu movies that wrap around people's necks and stuff.
