M6 Assault Rifle

Origin
The M6 Assault Rifle is the basic standard rifle used for the for the UANSF. The rifle was part of the M Series of rifles that ranged back from the early 1980's. The first model, the M1 was a semi-auto rifle that had many failures when it comes to loading magazines, scopes and the rate of fire. In 1982, the M2 was made with more upgrades and a better scope, this was the US's favorite weapon up until 1986 until the M3 was made. When the M3 was made, it turned into a bullpup rifle with cheaper materials to make. This rifle was then thrown out and was replaced with the M4. The M4 rifle had a grenade launcher on the bottom on the barrel, but reports came out saying that the grenade would prime and not fire which was a deadly factor in the rifle. Thus like many others, it and soon the M5 will be thrown out due to more technical problems.
