Magpul PMAG D-50 for CZ 9MM BLK

Lightweight but incredibly strong, Magpul's PMAG D-50 EV9 is a highly-reliable, 9x19mm Parabellum, 50-round drum magazine for large-format pistols and pistol caliber carbines that feed from CZ Scorpion EVO 3-pattern magazines. The D-50 EV9 features a ratcheting loading lever that removes tension from the internal spring. To keep track of your available firepower, they've included a rounds-remaining rear window and a high-visibility follower tip.
