The Area 419 ZERO M-Series 6mm BR Sleeve and Mandrel Reloading Kit provides modular sizing sleeves and a mandrel designed to deliver approximately 0.002″ of neck tension, matching the standard configuration of the complete M-Series dies. Note that this kit is a replacement sizing insert for M-Series dies and cannot be used as a standalone die—you must already own an M-Series die to utilize this product.
This kit offers a practical solution for reloaders who want to use the same M-Series die for different calibers without purchasing additional complete die sets. Each kit includes one sizing sleeve in the 6mm BR caliber that matches the internal sleeves found in complete dies, along with one mandrel delivering the standard 0.002″ neck tension. Designed for reloaders who already own an M-Series ZERO die, this kit lets you swap calibers or adjust neck tension without having to buy a full new die, maximizing your investment and boosting your reloading workflow.
The Area 419 ZERO M-Series design is capable of producing the finest match-grade ammunition while being user-friendly for both experienced and learning reloaders. Area 419 dies are 100% made in America and come equipped with an Area 419 Zero die ring, a spare decapping pin, and the necessary tools for installation and removal.
