ASGs Diabolo 4.5mm pellets are a basic flat head pellet type made from a clean refined lead, without admixture, which could affect the oxidation. The pellets are clean, free of debris and with a high metal shine.
This keeps the shooters hands clean and what is more important prevents debris, which could affect the function of the weapon, from accumulating in the mechanism and barrel. Resulting in a flawless operation and extended lifetime of the weapon.
