Frankford Arsenal Dielocker Die Lock Rings with Wrench - 3-Pack

Fine-tuning a reloading die to the exact specification your cartridge demands is where precision work separates good ammunition from great ammunition. The Frankford Arsenal Dielocker Die Lock Rings with Wrench—a 3-pack set—gives you the ability to dial in your die height with repeatable accuracy and then lock it in place without slipping. Each ring is machined from anodized aluminum, built tough enough to handle years of press time, and designed with a split-ring construction that grips your die threads securely while you work.

The genius here is in the details. Graduation marks spaced every .001" along the ring's surface let you make micro-adjustments with confidence, knowing exactly how far you're turning. Whether you're working with a progressive press crammed with toolheads or a turret setup with dies packed shoulder-to-shoulder, the included wrench is slim and compact enough to fit into spaces where standard tools simply won't reach. That matters when you're chasing consistency across a large batch and need to tweak your die without breaking down half your setup.

These lock rings work with any standard 7/8"-14 die, so they'll integrate into whatever press and die combination you're already running—rifle, pistol, or both. Once you dial in your die position and lock the ring down, your zero stays put until you deliberately change it. No more guessing whether your die shifted between sessions, no more wasted brass from inconsistent seating or sizing. If you reload seriously, these three rings will pay for themselves in the ammo you'll save.

Frequently Asked Questions

Will these lock rings work with my press and dies?

Yes, if your dies use the standard 7/8"-14 thread. That covers the vast majority of reloading dies sold for rifle and pistol cartridges, whether you're running them on a single-stage, turret, or progressive press.

How do the graduation marks help me reload better?

The marks let you measure die height in thousandths of an inch (.001"), so you can make tiny, deliberate adjustments and repeat them reliably. Once you find the exact position that gives you consistent ammunition, you can lock it in and come back to that same setting every time.

Can I use these on a progressive press where space is tight?

Yes—the split-ring design and included wrench are specifically engineered to work in the cramped toolhead spaces common on progressive and turret presses. The slim wrench lets you adjust without pulling apart your entire setup.

What comes in the 3-pack?

You get three die lock rings and one slim wrench. The three rings let you set up multiple dies or have backups on hand.
