Add New Weapon: AK5 Assault Rifle

The beauty that is the AK5 can't be understated, while at a core it is a FN FNC rifle, it has been modified for arctic climates in ways that gives it a truly unique appearance, I think it's one of those weapons that would be a welcome addition as it stands out from the generic AR15 and Kalashnikov variants! Pictures included show different variations and are presented as the base AK5, the AK5C variant and of course, the shorter AK5D variant, these could easily be achieved by just including separate barrel options.
