The guns are coated with more oil, which is not only inconvenient to use, but also prone to problems. In cold regions, because the temperature is generally low, the viscosity of the oil becomes larger, which will pull the "hidden legs" of the movable parts of the gun, and it will be prone to failure when shooting. If it is in areas with heavy sandstorms, the gun oil will be applied too much, and the gun body will be stained with sand and soil, leading to early wear and tear of moving parts. Although the current gun oil will no longer freeze and freeze like the previous gun oil, you still need to be extra careful when using it, and never let it touch the trigger of the bolt-type gun. A good trigger usually has a very precise manufacturing process, and even a little foreign matter may make it unable to work.
