Europe and USA

The carbines? Variants of the infamously shitty M16.

for the record, modern ARs constructed from quality parts are very competent and reliable firearms...versatile platforms as well, easy to work on and maintain, readily available parts, often chambered for some of the most common rounds out there...all in all, they're pretty hard to fault anymore
