Bench Mule Holding Fixture

The Bench Mule Holding Fixture by Mark Williams (Model 650) is a precision reloading and gunsmithing workbench tool designed for shooters, reloaders, and armorers who demand stability and repeatability during ammunition assembly, firearm modification, or component fitting work. This heavy-duty fixture provides a secure platform for holding rounds, receivers, or components in exact position while you perform critical operations—eliminating hand fatigue and ensuring consistent results. Whether you're processing match-grade ammunition, headspacing barrels, or fitting precision components, the Bench Mule delivers the hands-free security professional and competitive shooters require.

Built with industrial-grade construction to withstand repeated use and torque loads, the fixture's 19.8-pound weight and rigid 11 x 11 x 12.5-inch footprint ensure zero flex during precision work. The fixed bench mount design eliminates slip and movement, critical when tolerances demand repeatability to within thousandths of an inch. Mark Williams engineered the Model 650 for durability in high-volume reloading environments, where consistent clamping pressure and stable workholding directly affect ammunition quality and safety. The substantial weight distribution and low center of gravity keep the fixture anchored to your reloading bench, protecting both your work and your tools from accidental shifts.

The Bench Mule Holding Fixture is ideal for reloaders transitioning from hand-held operations to bench-mounted precision work, gunsmiths fitting custom components, and ammunition manufacturers seeking repeatable process control. Installation is straightforward—secure the fixture to any standard reloading or workbench surface and lock your components in place using the integral holding system. This tool integrates seamlessly into existing Mark Williams reloading press setups and stands alone as an essential accessory for anyone serious about ammunition consistency, barrel work, or gunsmithing quality. For competitive shooters, military armorers, and professional ammunition handlers, the Bench Mule represents a modest investment in safety, accuracy, and throughput.
