A potato cannon is NOT considered a Firearm in the US, but it IS considered one here?I know, Gun Laws in the US are much, much less strict than they are here in the UK, and fair enough if governments have different considerations - but if a Potato Cannon is NOT considered a Firearm in the US, WHY is it in the UK? For those of you who’ve ever felt the need to launch small pieces of potato at your fellow man (or woman), this is the perfect tool.

Any pneumatic with a potential power output exceeding 12 ft-lbs will also fit within either section 1 or section 5 (Section 2 cannot be air powered) A hybrid combines principles of combustion and pneumatic spud gun. It uses a pre-pressurised mixture of fuel and air to get more power out of a given chamber volume. Threaded Fittings: commonly available in BSP or NPT (not interchangeable) they generally require a fitting attached to a pipe by other means to allow screwing into another threaded fitting. The exception to this is steel pipe, the ends of which can have the appropriate thread cut into them.

In Iron Man 3, Tony meets a boy named Harley, who owns a potato gun which he uses to threaten Tony. At the end of the movie, as thanks for his help, Tony builds Harley a newer and better potato gun.Essentially, if you are a 18 year old, in a farm with no one around for 280 meters further than your projectile will fire, and you can show that it is NOT CAPABLE under any circumstance of producing more than the specified power and you are more than 50 feet from any roadway a car can travel on, you may win the court case. Your open field and tree belong to someone and probably have public access. This means that in spite of your best efforts someone will inevitably be injured. You must be very young or daft not to consider the consequencies of firing your gun in any circumstances as described. At the very least, one day the tube will weaken, rupture and discharge its contents in your direction.
