Magpul

Reinforced polymer magazine coupler allows you to clamp two 30-round PMAGs to each other for super-fast reloads because you’ll always have an additional 30 rounds with the gun. The two polymer links secured by two steel bolts hold both mags firmly, with no rattling or play. Designed for use with current-production PMAG and MagLevel PMAG only.

SPECS: Reinforced hard polymer, matte black. Fits current-production 30-round PMAG and MagLevel PMAG. Not compatible with the first generation PMAG with black follower, 20-round PMAG, EMAG, PMAG 30G, or 7.62/.308 PMAG.
