The PMAG D-50 MP boasts many of the proven features of our other 9mm drums, the PMAG D-50 GL9 PCC and the PMAG D-50 EV9 CZ Scorpion EVO 3. Providing 50-round capacity, the unique drum configuration keeps the height of the magazine manageable, allowing for prone firing and easier storage. For easy loading, it includes a ratcheting loading lever that removes tension from the internal spring. To keep track of your available firepower, we've included a rounds-remaining rear window, a high-visibility follower and a capacity indication roller. And like our other drum magazines, the PMAG D-50 MP is easily disassembled for cleaning and maintenance. Made in the USA.
