Real Avid Smart Bench Block

4Made from engineering grade resin, this intelligently designed gunsmith block helps protect gun finishes. The non-slip outer ring keeps the block from sliding on tables or benches while driving pins. An embedded magnet captures and holds driven pins so that they won't roll away. A rounded slot seats barrels and gun slides for increased stability. Designed to work with most guns. Makes the job easier and faster!Specifications and Features:Material: ResinNon Slip Outer RingMagneticWorks with most guns
