It's a pretty good gun for fighting. It has good accuracy and doesn't have much recoil because of only being able to shoot only one bullet. The damage is also good and it will always have ammo since Stanag magazines are very common. This gun is best for medium distances and can be made into a "sniper" rifle if you have a long range sight.
