The Brownells Gunsmith Bench Vise Jaw in Polyurethane Prism is a precision replacement insert designed to protect delicate and cylindrical workpieces during gunsmithing, machining, and repair work. These soft jaw inserts slip over the factory steel jaws of your Brownells Gunsmith's Bench Vise, letting you customize your setup for specific projects without risk of marring or damaging the parts you're working on. The polyurethane prism design is engineered specifically for round and oval workpieces, making it an essential upgrade for gunsmiths, tool makers, and machinists who regularly handle finished components that can't tolerate the bite of hardened steel.
What sets the polyurethane prism jaws apart is their geometry and material science. The "prism"-shaped cutouts of various sizes are machined into the face to position round and oval parts securely in the vise without requiring excessive clamping force. The polyurethane itself is engineered to stay flexible and resilient—it resists permanent deformation and won't harden with age, so your jaws remain effective long after installation. An aluminum body houses powerful rare-earth magnets that hold the inserts firmly in place on your vise, and the aluminum construction prevents those magnets from accidentally magnetizing the steel parts you're working on.
If you're building an AR, refinishing a rifle, or performing detailed gunsmith work, these jaws give you the control and protection you need. They're a straightforward upgrade that transforms your bench vise from a brute-force clamp into a precision tool capable of handling finished barrels, receivers, bolts, and other components that demand a gentler grip. Simply remove the factory jaws and slide these inserts over them—no permanent modification to your vise required.
