Configuration in which the firearm action/mechanism and magazine are located behind the trigger
The main advantages of the bullpup layout apply to military rifles, in which a target-type trigger is not even wanted, let alone needed.However until someone develops a better way to do the trigger mechanism you still end up pulling a trigger moving a bunch of real long rods and such so I can't imagine you can get a crisp, short, light trigger like the JP trigger in my AR.
