The Lee 1 1/2"-12 Breech Lock Update Kit converts existing press frames to accept Lee's Breech Lock quick-change bushing system, enabling tool-free die cartridge swaps without removing the press head. This upgrade kit is essential for reloaders who operate large-frame presses and want to streamline workflow on dedicated caliber setups or high-volume production runs.
The kit contains a 1 1/2"-12 breech lock adapter, spline drive lock-ring eliminator, and lock-ring wrench. The 1 1/2"-12 specification denotes the thread pitch and diameter required for press compatibility. Installation converts green, red, or blue frame presses—including Hornady 50 BMG, Dillon BFR 50BMG, and RCBS AmmoMaster 2 models—to quick-change capability without modification to the press structure. The included wrench ensures proper lock-ring removal and installation, critical for consistent bushing seating and concentricity.
This upgrade serves precision rifle and large-caliber handgun reloaders who switch between multiple die sets or calibers. The Breech Lock system minimizes press downtime and reduces the risk of cross-threading or damaging delicate die threads during removal and installation. Reloaders operating 50 BMG presses or high-precision cartridge reloading setups benefit most from this conversion, as the quick-change feature accelerates caliber transitions and setup changes between range sessions or production batches.
