The Lee Precision 90600 Breech Lock Quick Change Bushing transforms die changes from a tedious threading process into a simple twist-and-lock operation. This 2-pack of silver anodized aluminum bushings eliminates the need to screw dies in and out of your press, reducing setup time and preventing cross-threading damage to expensive dies.
What Makes This Different
Unlike traditional die mounting systems that require threading dies directly into the press, the Breech Lock system uses pre-threaded bushings that lock into place with a quarter-turn. Each die screws into its own dedicated bushing once, then the entire assembly drops into the press and locks with the cam-lever mechanism. This eliminates the 3-4 full rotations typically needed to seat a die properly.
Key Features
- Quick-change cam-lever locking mechanism reduces die changes to seconds
- Precision-machined aluminum construction with silver anodized finish
- Standard 7/8"-14 TPI threading compatible with all major die manufacturers
- Prevents cross-threading damage to expensive die sets
- Maintains consistent die height and alignment between changes
- Two bushings allow pre-setup of multiple calibers or die types
- Compatible with all Lee Breech Lock presses and many other brands
Reloaders working with multiple calibers benefit significantly from the time savings during session transitions. Competition shooters can switch between practice loads and match ammunition dies in under 30 seconds. The consistent die positioning eliminates the need to re-adjust seating depth or crimp settings when switching between previously configured setups.
