Area 419 Zero M-Series Die Sleeve And Mandrel Kit .300 Prc
$160.00
If you're running Area 419's ZERO M-Series die for .300 PRC, this sleeve and mandrel kit unlocks the modular flexibility that makes these dies a game-changer for precision reloaders. The kit gives you an extra sizing sleeve in .300 PRC caliber, a full-length ground mandrel tuned to deliver consistent neck tension, and a spare decapping pin—everything you need to maximize what your M-Series die can do. This is a replacement insert package, so it's built for shooters who already own an M-Series die and want to expand their capability or have a backup setup ready to go.
Area 419 engineered the M-Series platform around micrometer-adjustable headspace control and modular construction, so you're not locked into one caliber or configuration. Swapping sleeves means you can tune your sizing to different .300 PRC loads or brass batches without buying an entirely new die. The mandrel is ground to spec and spring-loaded in the die body, delivering the same controlled neck tension as the original—about .002" in use—so your rounds chamber reliably and behave predictably downrange.
This kit is straightforward: one sizing sleeve, one mandrel, one decapping pin. No fluff, just the components serious long-range and competition reloaders depend on. If you've already committed to an M-Series die and want to streamline your workflow or keep a spare mandrel in rotation, this is the move.
What's Included
- One .300 PRC sizing sleeve (replacement insert)
- One full-length ground mandrel (~.002" neck tension)
- One extra decapping pin
Frequently Asked Questions
Do I need an Area 419 ZERO M-Series die to use this kit?
Yes. This is a replacement insert and mandrel package designed exclusively for owners of an M-Series die. It is not a standalone die and cannot be used without the complete M-Series die body.
What caliber is this sleeve and mandrel kit for?
.300 PRC. The sleeve is cut to size for that cartridge and will not fit other calibers.
What kind of neck tension does the mandrel deliver?
The mandrel is ground to produce approximately .002" of neck tension during sizing, matching the specification of the mandrels that ship with the complete M-Series dies.
Can I use this to convert my die to a different caliber?
No. This kit is a replacement sleeve and mandrel in .300 PRC only. It allows you to have a backup mandrel or extra sizing sleeve for the same caliber, or to swap between setups, but it does not change the die to reload a different cartridge.
