If you're running Forster Co-Ax XL dies or any standard 7/8"-14 threaded die, you know that a solid lock ring is where precision starts. The Forster 1-1/4" - 7/8" Adaptor Crossbolt Die Lock Ring replaces the typical screw-down design with a cross-bolt clamping system that grips the entire circumference of your die. This six-pack gives you the security of repeatable, damage-free die seating—crucial when you're chasing tight groups and consistent case feeding.
The crossbolt design eliminates the weak point of traditional lock rings: threading a screw directly into the die itself. Instead, the cross bolt clamps both ends of the ring with even pressure, keeping everything in perfect alignment without stripping threads or causing runout. It's the same engineering Forster builds into their premium Bench Rest Dies, and now you can retrofit or upgrade your existing setup. Tightening and loosening takes nothing more than a 7/64" hex key—straightforward, repeatable, and dead reliable at the reloading bench.
Built for reloaders who understand that the small details compound into better ammunition. Whether you're upgrading from stock lock rings or outfitting a new press setup, this adapter bridges the gap between standard die threads and the clamping security you need to hold zero. Six rings per pack means you can equip a full die set or keep spares on hand.
| Brand | Forster |
| Product Type | Die Lock Ring Adaptor |
| Outer Diameter | 1-1/4" |
| Die Thread Size | 7/8"-14 |
| Fastener Type | Cross Bolt |
| Hex Key Size | 7/64" |
| Quantity per Pack | 6 |
| Compatibility | Forster Co-Ax XL Dies; Standard 7/8"-14 threaded dies |
This adaptor fits Forster Co-Ax XL dies and any standard 7/8"-14 threaded dies from most major manufacturers. It clamps onto dies with that standard thread pitch.
A traditional lock ring threads a screw directly into the die threads, which risks stripping and uneven clamping pressure. The crossbolt design clamps around the entire circumference of the ring, distributing pressure evenly and keeping the die perfectly aligned without damaging threads.
You'll need a 7/64" hex key (Allen wrench) to tighten and loosen the cross bolt. It's a simple, quick operation at the reloading bench.
You get six lock rings per pack, enough to outfit a full set of dies or maintain spares for your reloading operation.
