Brownells Gunsmith Bench Vise W/Replacement 4.75'' Jaw

The Brownells Gunsmith Bench Vise with replacement 4.75" jaw is a forged-steel workhorse built for serious gunsmithing. Unlike cast vises that can fail under pressure, this German-engineered tool is drop-forged throughout for the strength needed to handle barrel removal, installation, and other high-torque gunsmithing tasks. If you're setting up a serious bench or upgrading from a general-purpose vise, this is the kind of tool that earns its place for decades.

The 4.75" precision-aligned jaws feature hardened steel faces designed to accept interchangeable magnetic jaw inserts, so you can protect your firearm components and customize your grip for different jobs. The jaws are reversible—choose a smooth face or checkered texture depending on the task—and they're replaceable when wear eventually takes its toll. The included replacement jaw gives you a ready backup, and additional inserts are available separately to expand your capability without replacing the whole vise.

Construction details matter here. The drop-forged guide tracks have fully machined surfaces for smooth, consistent clamping depth, and they resist the kind of fouling that slows down cheaper vises. A centrally positioned spindle with double-action trapezoidal threading distributes clamping force evenly, while the electro-galvanized spindle assembly resists corrosion. Even smaller components—guide plates, spindle nut, protective bearings—are engineered for durability and precision alignment. The green finish echoes Brownells' classic Multi-Vise heritage while protecting against rust.

Mount it directly to your workbench or pair it with an optional rotating base for flexibility. This vise hits the sweet spot for gunsmithing: substantial enough to muscle stubborn barrels and assemblies, but sized for a working bench rather than an industrial shop.

Frequently Asked Questions

What's the difference between this forged vise and a cast bench vise?

Forged steel has inherent strength and flexibility that cast iron lacks. Cast vises are prone to brittleness and can fail under the high torque involved in barrel work. This vise's drop-forged construction—in the jaws, guide tracks, spindle nut, and guide plates—delivers the durability needed for serious gunsmithing without flexing or breaking under load.

Can I use different jaw inserts on this vise?

Yes. The 4.75" jaws accept interchangeable magnetic jaw inserts designed for specific gunsmithing tasks. Inserts are available separately, so you can build a setup tailored to the work you actually do. The jaws themselves are also reversible (smooth or checkered) for different grip needs.

What comes with this vise?

The Brownells Gunsmith Bench Vise includes a replacement 4.75" jaw. You mount it directly to your workbench or add an optional rotating base for added flexibility. Additional jaw inserts are sold separately.

How do I mount this vise to my bench?

The vise bolts directly to your workbench. Optional rotating bases are available separately if you want added flexibility for positioning work at different angles.
