Brownells
The Brownells Gunsmith Bench Vise Jaw in aluminum prism is a specialized jaw insert designed to extend the versatility of your Brownells Gunsmith's Bench Vise for precision gunsmithing and shop work. Rather than relying on factory steel jaws alone, these aluminum prism jaws let you customize your clamping setup for the specific workpiece or project at hand. The aluminum construction offers a hardness factor between copper and lead—soft enough to protect finished parts from marring, yet rigid enough to hold securely under clamping pressure.
Built into the face of these prism jaws are multiple V-shaped and curved cutouts in different sizes, engineered to cradle and position round and oval workpieces without slipping. The horizontal prism-shaped main channel pairs with three vertical prism options to accommodate various barrel diameters, receiver profiles, and similar cylindrical components common in gunsmithing. A 90° cutout in the upper section also handles flat material when you need horizontal clamping. These jaws slip directly onto the factory jaws of your Brownells vise and are held in place magnetically—the aluminum body prevents the rare-earth magnets from interfering with steel parts in the jaws.
If your work involves delicate actions, barrels, or finished surfaces that can't tolerate steel jaw marks, aluminum prism jaws strike a practical middle ground: they're durable enough for regular shop use but far softer than hardened steel. They're one of several interchangeable jaw options Brownells offers, so you can keep your primary vise mounted on the bench and swap inserts as your project demands.
| Material | Aluminum |
| Attachment Method | Magnetic (rare-earth) |
| Compatibility | Brownells Gunsmith's Bench Vise |
| Clamping Profile | Round, oval, and flat workpieces |
These jaws are designed for the Brownells Gunsmith's Bench Vise. They slip over the factory jaws and attach magnetically.
No. The aluminum material is significantly softer than hardened steel or the finished surfaces of gun parts, so it will not scratch or mar barrels, receivers, or other precision components under normal clamping pressure.
The prism-shaped cutouts are engineered for round and oval workpieces—barrel blanks, receiver tubes, and similar cylindrical components. The multiple prism options accommodate different diameters. The 90° cutout also handles flat material when needed.
Yes, they attach magnetically to your vise. However, the aluminum body prevents the rare-earth magnets from magnetizing steel parts held in the jaws, so your workpieces won't become magnetically charged during clamping.
