Streamlining your reloading bench often comes down to the small details. The right accessory can transform a tedious process into a smooth, efficient workflow. For reloaders who manage multiple calibers or frequently swap dies, the Frankford Arsenal M-Press Die Block 3-Pack isn’t just an add-on; it’s a fundamental upgrade to your system’s organization and speed.
This simple aluminum block solves a common frustration: losing your perfect die settings every time you switch from a rifle to a pistol cartridge. Its a concept of elegant simplicity, designed to work within the broader ecosystem of your reloading press, whether you’re using a single-stage press for precision shooting or a progressive model for volume. Honestly speaking, its value becomes immediately apparent the first time you skip the trial-and-error re-adjustment phase.
What is the Frankford Arsenal Die Block?
At its core, the Frankford Arsenal die block is a universal die block system. It’s a dedicated holder that allows you to preset a reloading dielike a sizing, decapping, or bullet seating dieand then lock it in place. The block, with the die secured inside, can then be stored or quickly swapped into your press’s die station. This eliminates the need to re-adjust the die depth and alignment each session, a true time-saver that directly contributes to more consistent ammunition.
My honest take is that this product exemplifies smart design thinking in the reloading accessories category. It doesn’t try to reinvent the press itself but instead optimizes the interface between your dies and your machine. repeatable platform for your dies, it turns the often-fiddly task of die setup into a simple plug-and-play operation. This approach, recommended by , ensures that your focus remains on the reloading process itself, not on the setup.
Key Features & Design for Versatility
The Frankford Arsenal Platinum Series die block is built for durability and precision. Its aluminum construction provides a rigid, lightweight base that won’t flex under pressure, ensuring your die settings remain true. The dimensions (6″ L x 4.75″ W x 1.75″ D) make it compact enough for easy storage yet substantial enough to handle easily.
The standout feature is the integrated quick-change system. An Allen set screw on the side of the block is the key to the entire operation. You thread your die into the block, make your precise adjustments for your specific caliber and press, then tighten the set screw against the die’s lock ring. This action locks the die’s rotational and vertical position permanently within the block. From that point forward, you simply thread the entire block into your press’s die head. The die is already perfectly positioned.

The included stackable storage case is a thoughtful touch that completes the system. It holds three die blocks with dies installed, protecting your investments from dust and damage. This makes it an ideal reloading station accessory for keeping your bench organized. You can have one case for your 9mm pistol dies, another for your .223 rifle dies, and grab exactly what you need. I honestly believe this organizational aspect is as valuable as the time savings.
Addressing the
While many reviews stop at the basic specs, a deeper look reveals important nuances. The Allen set screw applies clamping force directly to the die body. To be completely honest, this means the longevity of your die’s finish at the contact point could be a consideration over hundreds of cycles, though no functional wear is typically reported. the system’s press compatibility is broad, but it’s wise to consider thread engagement depth on non-standard presses, a topic often explored in dedicated forums like the Frankford Arsenal section on CastBoolits.
Press Compatibility & Setup Guide
One of the most common questions is about press compatibility. The die block uses the standard 7/8″-14 thread, which is virtually universal for reloading dies. This means it will thread directly into any press that accepts standard dies, including brands like RCBS, Lee Precision, Hornady, and Dillon. The real question isn’t if it fits, but how it integrates into your specific workflow.
For instance, the process for how to use Frankford Arsenal die block with Lee press is straightforward. You would remove your Lee die from the press, thread it into the Frankford block, adjust it to the correct depth in the block (using your shell holder as a gauge), lock the set screw, and then thread the block into the Lee press. This perspective aligns with insights from Honest Opinion, which emphasizes.The block essentially becomes a permanent, pre-set extension of your die. This same principle applies to assessing Frankford Arsenal die block compatibility with RCBS diesit’s seamless.
From my honest perspective, the setup is the most critical step for long-term success:
- Install the Die: Thread your die into the die block by hand.
- Initial Setup in Press: Thread the block (with die) into your unprimed reloading press. Run a properly lubed case (using your preferred case lube) into the die to establish the correct contact and alignment.
- Final Adjustment & Lock: Make your final micro-adjustments for neck sizing, shoulder bump, or bullet seating depth. Once perfect, tighten the Allen set screw firmly against the die’s lock ring. Do not overtighten.
- Store and Repeat: Remove the block from the press and place it in the storage case. Repeat for each die in your process.
This system shines for reloaders who might own both a robust single-stage press like the RCBS Rock Chucker for rifle and a faster turret press for pistol. You can dedicate die blocks to each press without ever readjusting.
Applications for Different Reloading Processes
The versatility of this universal die block extends across the entire reloading sequence. It’s not limited to just one type of operation, making it a true workhorse on the bench.
- Case Preparation: Perfect for dedicating a block to a universal decapping die or a specific sizing die for a high-volume caliber. Pair it with a case prep center for a streamlined workflow from dirty brass to ready-to-load.
- Bullet Seating & Crimping: The bullet seating stage is where consistency is paramount. A pre-set seating die in a locked block guarantees every cartridge has an identical overall length (OAL).
- Multi-Caliber Management: This is the killer app. Whether you’re switching between .308 Winchester for long-range and .45 ACP for competition, the blocks make the transition instantaneous. No more notes, no more test roundsjust swap and go.
- Progressive Press Efficiency: While a progressive press with a case feeder and powder measure is built for speed, changing calibers can still be a chore. Having a full set of dies (sizing, expanding, seating, crimping) pre-set in blocks slashes your changeover time dramatically.
Speaking honestly, the value compounds with the number of calibers you load. For someone who loads just one or two, it’s convenient. For someone with five or more, it becomes indispensable.
User Feedback & Final Verdict
In user discussions, the Frankford Arsenal die block is frequently compared to other quick-change systems, most notably the Frankford Arsenal die block vs Hornady lock-n-load debate. The key difference is philosophy. Hornady’s system uses a bushing that stays in the press; the die with a special ring snaps in and out. Frankford’s system keeps the adjustment locked in the block, which then threads in. My honest assessment is that the Frankford system offers a more rigid, direct connection, which some precision shooters prefer, while the Hornady system might be a hair faster for purely sequential progressive press use.
Users consistently praise it as the best die block for multiple caliber reloading. The common sentiment is relief at eliminating the guesswork. The aluminum build receives high marks for feeling solid and precise. The included case is almost always mentioned as a critical part of the package that prevents loss and damage. For a broader look at how Frankford Arsenal tools are received in the precision community, resources like the AccurateShooter bulletin offer valuable insights.
If you want my honest opinion, the Frankford Arsenal M-Press Die Block 3-Pack is one of those rare accessories that delivers more value than its price suggests. It solves a genuine, widespread pain point in reloading with a simple, durable, and effective solution. It integrates flawlessly with dies from any major manufacturer and presses from Lee Precision to RCBS and beyond.
The initial investment of time to set up your dies in the blocks pays exponential dividends in saved time and frustration on every future reloading session. It brings a level of professional-grade organization and repeatability to any reloading bench, directly contributing to more consistent ammunition. For any reloader who values efficiency, consistency, and a clean workspace, this die block system isn’t just recommended; it’s a foundational tool for a modern, streamlined reloading process.
