Lee Breech Spline Drive Breech Lock Bushing with Die Lock Ring Eliminator 2/ct

The Lee Breech Spline Drive Breech Lock Bushing with Die Lock Ring Eliminator (2-count pack) is a quick-change die-mounting system designed to eliminate the need for traditional lock rings on reloading press dies. The spline-drive design provides a secure, accurate interface between the die and press bushing while maintaining fast tool changeover—essential for reloaders who process multiple calibers or switch between precision rifle and high-volume handgun loads.

Each bushing features an easy-grip splined drive surface that allows rapid, accurate die installation without fumbling with conventional lock rings. Once lightly tightened, the split collar clamps the die in place with vise-lock force, holding position precisely. Loosening the clamp screw frees the die to rotate and spin out smoothly. This two-pack provides redundancy for shooters maintaining multiple reloading setups or those running parallel stations for high-volume ammunition production. The bushings are compatible with standard Lee press equipment and maintain die concentricity across multiple load sessions.

This system is ideal for reloaders who value speed without sacrificing accuracy—competitive shooters, hunters preparing large quantities of ammunition, and those loading for multiple calibers benefit most from quick-change capability. The die-lock ring eliminator approach reduces setup time between load changes, meaning more rounds loaded per session and faster transitions during range testing or practice days. Reloaders working with tight budgets for components appreciate that eliminating separate lock rings reduces wear on dies and bushings over thousands of reload cycles.

Lee Precision's reloading equipment is established in the handloading market for no-frills, function-first design. The Breech Spline Drive system represents a genuine productivity upgrade for operators already committed to the Lee ecosystem. Whether loading match-grade rifle ammunition or high-volume pistol rounds, this bushing pair reduces friction in the setup workflow and ensures consistent die positioning across reload sessions.
