The GMS 622 is a primary weapon for the Gunner class in Blitz Brigade. It is a typical machine gun with a box magazine. For stats, it deals 110 damage, which is better than a Belyov or any of the beginning machine guns that the Gunner can equip, while the range, and critical chance are either the same or a little bit better. However, the rate of fire is the amazing, and this gun has the highest rate of fire out of ALL the weapons, making this somewhat overpowered. When in battle, the reload time is lengthy and the accuracy is not that great, considering the fact that it is an LMG. Overall, the GMS 622 is a great weapon for 60,000 coins. It costs 50 diamonds to upgrade. It is based off of the Stoner 63 (more specifically the MK23 MG).
