The MK-5 is the basic assault rifle carried by United States Marine Corps. It has two main weapons: A 10mm and a 7.62x51mm bullet (below the 10mm) for sniping. It is better known for its durability and devastating fire power.
The MK-5 was invented by a weapon specialist named Art Karnak. He invented the gun after he was brutally injured in battle. Art wanted a way to improve warfare. He decided to create a gun that would be useful for CQB and sniping. It took him three years before he invented the first MK-5 ever. He later gave it to the US Army. The US Army was so impressed by his gun that they switched their old A-14s for the new gun. Karnak later died in 2020. General Victor Malkovich honored him with the Red Eagle Medal for inventing such a great gun.
