NOTE: Low cap and mid cap mags are spring loaded. Simply fill with BB's and shoot. The high cap mags are gear driven and must be manually wound before shooting. It is common for high cap mags to not shoot all of the BB's inside, due to the nature of the gear system. Please be careful not to over-wind high cap mags or they may strip a gear. *High capacity magazines carry no warranty*
