    Assuming the site is from the US, I don't see why it would or should be illegal. What is more dangerous to the public, a psycho with a homemade mortar or a psycho with a semi-automatic handgun. I guess the mortar would be able to do some serious structural damage, but I can do some serious damage with my car, and more idiots drive than build their own cannons.

  3. Wow... by Zzootnik · · Score: 5, Informative

    Okay- Sure, It's a Darwin award waiting to happen, but WOW... There's just something about explosives and that much kinetic energy... I used to shoot off the BIG July 4 fireworks...the normal "dinky" 3 inch shells are pretty pounding, but the bigger 10"+ shells were just pure Concussion.( And that's just from the launch-) Lotsa material there to feed your inner pyromaniac...

    I'd still be pretty spooked about flying metal shards here, though. I've seen the aftermath of firing tubes that have ruptured, and you really can't imagine how steel can twist and rip like paper until you've seen it. There was a REASON we buried those tubes....

    And no, it's not considered a shotgun. And this has been the law for a -long- time.
