Ruger SR-556 5.8 SPC 5-Round Magazine 6.8mm Rem SPC Black Steel

The Ruger SR-556 5.8 SPC magazine delivers reliable feeding for the intermediate cartridge that bridges the gap between 5.56 NATO and larger calibers. This factory magazine ensures consistent performance with the enhanced ballistics of 6.8mm Remington SPC ammunition.
