The Lee Lock Ring has been reimagined to make the traditional design obsolete. With the introduction of the split clamp spline drive, this new lock ring offers a more efficient, secure and user-friendly experience. The high-strength aluminum construction features a splined exterior surface, ensuring a firm grip on your dies. By splitting the ring and adding a cross bolt, it applies a vice-like grip with even light pressure eliminating the need for tiny set screws that can easily strip or damage die threads. Additionally, the lock ring incorporates the famous Lee "O" ring, which helps prevent loosening during operation. No matter how tightly you clamp the lock ring onto your die, the "O" ring creates enough friction to keep it securely in place while still allowing easy removal with just finger pressure. This innovative design makes die installation a breeze, especially when fitting dies onto a turret or tool head. For added convenience, the lock ring wrench (sold separately) simplifies the process of installing and adjusting dies, making the entire reloading setup faster and easier.
