Constructed fully from metal with a high tension internal spring, this magazine can easily withstand hard drops and a high rate of fire. What differentiates this magazine from the classic version is the new and improved Quick-Piercing winding wheel which drastically cuts down the time it takes to change out Co2 cartridges.
