The PUBG mobile 3x scope is too zoomed for use in close combat and yet not good for long-range. It is better used in close to medium range. So the best distance to use the 3x scope is 100 m to 150 m in the final circle zone. One problem with the 3x scope is its reticle. The reticle is too cluttered which is odd. It consists of three-quarters of a circle divided into three parts. There is a plus sign in the center and a line that starts thinner at the contact point with the plus and goes thicker.
