How about making a mortar
 

has anyone given some thought of a mortar type gun. powered by CO2? like mabey that would shoot a grenade with parachute in a sleeve that falls off after leaving barrel? I may be crazy but i thought it might be interesting. any already made/ ideas/ suggestions/ reasons not to have one would be great

We made a potato gun that shoots screacher darts and used it as a mortar.

zero delay on these forums already makes them. And pretty damn good ones, too!!

cool ill look into that. we have some big hills that would work good for mortars i think

it's been done, JSOC makes and deploys them

any pics??

plans? so i can make my own some day?

Sorry our design is patent pending. Yes I know it's designed off very common knowledge and a super simple idea, turns out we're the first people to put a patent on it lol

Be careful with the breadth of your patent claims ThunderCactus. If you make claims on stuff that you didn't first invent, then those claims can be easily invalidated. A typical tactic to beat an infringement suit is to attack the validity of a patent. If an infringer can show that others had developed similar mechanisms before you did (e.g. point to someones website, or a potato cannon forum) they may be able to argue that you were not the first inventor and your claim could be invalidated.

Patent rights in North America are granted on a first to invent basis, not first to file.

I will probably get flame for this about the safety of fireworks but what if you used a regular fireworks mortar but filled it with bbs and it blew up in the sky and rained down bbs.

It is against the Explosives Act to "unmake" an explosive and moreso to "manufacture" one, and amateurs messing around with explosives is generally a bad idea. Besides, why would you pay $5 for a cardboard tube full of gunpowder for one shot - sitting in the field flicking your Bic - when compressed air is free and firing involves pushing a button?

I've had the opportunity to see both zero delays and JSOCs weaponry first hand and they are fabulous pieces of kit!

yes compressed gas is the way to go. and how much do these kits usually cost?
