Stabilizing your AR-15 lower during assembly or maintenance is essential to avoid damage and ensure a secure fit. A vise block designed for this purpose helps prevent wobble and protects your receiver from scratches or dents.

This high-density copolymer block stands out for its non-marring surface and precise fit, making it a reliable choice for anyone working on AR-15 lowers at home. It's especially well-suited for those who want a USA-made, durable tool that won't mark up their firearm.
