Frequently Asked Questions

What is a lower receiver vise block used for?

A lower receiver vise block securely holds an AR platform lower receiver in a bench vise while you work on it. This keeps your hands free and provides a stable platform for installing trigger assemblies, safety levers, stock hardware, or any other lower-end components without risking damage to the receiver finish.

Will this vise block work with my AR lower?

This block is designed for AR platform lower receivers. If you have a standard AR-15 or AR-10 lower, this vise block will accommodate it. For other platforms or custom designs, verify fit before use.

Does it fit a standard bench vise?

Yes, this vise block is designed to work with standard bench vise jaws.

Does the polymer protect my lower from scratches?

Polymer construction is gentler on finished lowers than bare metal jaws, helping prevent dings and marring during clamping and work. For maximum protection, ensure even clamping pressure and avoid over-tightening.
