Alexander Arms® .50 Beowulf 10-Round Magazine – Black Steel – MEB5010
The Alexander Arms .50 Beowulf 10-Round Magazine (MEB5010) is the 2026 definitive feeding solution for the hardest-hitting cartridge available on the AR-15 platform. While standard 5.56mm magazines can sometimes be modified, this factory-original magazine is precision-engineered specifically for the unique geometry of the .50 Beowulf. The heat-treated steel body features specialized feed lip geometry and a modified internal rib structure designed to prevent the "nose-diving" and binding issues common with large-diameter, straight-walled cartridges. This ensures that whether you are running 200gr flat-point rounds or heavy 400gr subsonics, your rifle cycles with absolute reliability.
Finished in a durable black matte coating, the MEB5010 (819511020090) utilizes a high-visibility, non-tilt follower and a heavy-duty chrome silicon spring to maintain consistent upward pressure. For 2026, Alexander Arms has reinforced the floorplate design to better withstand the violent recoil forces inherent to the .50 Beowulf. As a factory component, this magazine is built to the exact Technical Data Package (TDP) specified by Bill Alexander himself. For the big-bore enthusiast, using the MEB5010 is the single most important step in ensuring your "thumper" remains a reliable tool for hunting, defense, or recreational shooting.
Includes: (1) Alexander Arms .50 Beowulf 10-Round Steel Magazine.
