[i]Equestrian Projectile Weapons Technology[/i]

Given certain references in the show (including the existence of Pinkie’s party [i]cannon[/i] and RD saying she wanted a pet ‘as fast as a bullet’ and Tank was named such because he’s ‘tough like a Tank’, I’m going to put The Missing Legacies Universe Equestria’s standard weapons tech at about Columbus’ time in history. Flint lock weapons and naval cannons, but most of the rest is dealt with by much older methods due to unspecified circumstances. Nothing more high-tech than a flintlock rifle for single pony weapons, when it comes to black powder, and magical weapons are not much farther ahead. 

As for the legislation surrounding them, Equestrian has outright outlawed any projectile weapon that is gas or magic propelled, so nothing more powerful than a repeating crossbow (which seriously toes the line) is allowed to be used in the country, outside of Equestrian Navy and Airforce cannons on the air and naval vessels. Things like potato cannons are exceptions, because law defines a projectile weapon in terms of metres per second projectile speed, and type of projectile fired.
