Hornady Lock-n-load, Horn 399697 Qd Univ Mounting Plate Assembly DEMO/USED

The Hornady Lock-N-Load Quick Detach Universal Mounting Plate Assembly is a bench-mounted solution designed for reloaders who work with multiple progressive presses or tools on a single bench. Instead of bolting each press permanently to your workspace, this system lets you mount aluminum blocks to your bench once, then quickly swap presses and accessories in and out without tools or lengthy setup. It's especially valuable when bench real estate is tight or you run different calibers, gauges, or equipment on a rotation.

The assembly uses cam locks that hold everything rock-solid during reloading but release instantly for press changes. The mounting plate features hole configurations that accommodate a range of Hornady tools—including the Lock-N-Load AP, Iron Press, Classic 50 BMG, 366 Auto Shotgun Press, Bullet Feeders, Cam Lock Trimmer, and Concentricity Tool—so you can build a versatile reloading station around your workflow without reinventing your bench each time.

This is a demo or used unit, so it comes with real-world experience already built in. If you're consolidating your press setup or tired of permanent mounting bolts, this system pays for itself in convenience and flexibility.

Frequently Asked Questions

What Hornady presses and tools does this mounting plate work with?

The Lock-N-Load Quick Detach Universal Mounting Plate Assembly is compatible with the Hornady Lock-N-Load AP, Iron Press, Classic 50 BMG, 366 Auto Shotgun Press, Bullet Feeders, Cam Lock Trimmer, and Concentricity Tool. The universal hole configuration is designed to fit a variety of presses and reloading tools, so check your specific equipment against these compatible models.

How does the quick-detach system work?

The assembly uses cam locks that secure your press firmly to the mounting plate during operation. When you're ready to switch tools or presses, the cam locks release quickly, allowing you to remove the plate and install another without bolting or unbolting anything to the bench itself.

Can I use multiple mounting plates on one bench?

Yes. You mount the aluminum blocks to your bench once, then swap different plates—each with a different press or tool attached—depending on what you're reloading that session. This approach works well for high-volume reloaders or those juggling multiple calibers or equipment types.
