Lee 1 1/2"-12 Breech Lock Update Kit

The Lee 1 1/2"-12 Breech Lock Update Kit is designed for reloaders looking to enhance their existing press frames by integrating Lee's Breech Lock quick-change bushing system. This upgrade allows for tool-free die cartridge swaps, significantly improving workflow efficiency for those engaged in dedicated caliber setups or high-volume production runs.

The kit includes a 1 1/2"-12 breech lock adapter, spline drive lock-ring eliminator, and a lock-ring wrench, all essential for ensuring proper installation and removal of die sets. The 1 1/2"-12 specification indicates the necessary thread pitch and diameter for compatibility with various press models, allowing for seamless integration without structural modifications.

Reloaders utilizing large-frame presses, such as the Hornady 50 BMG, Dillon BFR 50BMG, and RCBS AmmoMaster 2, will find this conversion particularly beneficial. The Breech Lock system minimizes downtime and reduces the risk of damaging delicate die threads, making it an ideal choice for those frequently switching between multiple die sets or calibers.
