The point of a Light machine gun or Squad Automatic Weapon or IAR is to hit targets that rifles can hit at.This is more of a CQB gun that would apply for Say navy seal's,Green berets etc etc

well it optimal ranges are close quarters but can be use at median range with short controlled bursts and caliber is small but they are armor piercing and the bullets are sharper them most and is made out of a metal that is poisonous so if it misses a vital organ the victim would be dead in a few hours and its not spec ops but the barrel is short to make it a bit more compact

looks awsome,not so good at long range killing more used as CQB? This version look's like a special ops due to the short barrel.Awsome job though what caliber is this?

Nice! I like the magazine, oh and ill email you some pictures of the design and mechanism of some of my guns.
