Precision Reflex, Inc. Run Out Rig Concentricity Gauge

Precision tool helps eliminate those unexplained flyers by showing the exact amount of bullet run out and allowing the user to gently tweak the bullet and case into correct alignment. Helps you improve round-to-round consistency for more consistent groups. By rotating the cartridge and using the lever adjuster to push on the side of the neck that reads "high" on the indicator, the cartridge can be adjusted until the dial shows no more run out. Versatile, too: works with everything from the 221 Fireball to the 50 BMG. May be set up for left or right-hand use. Mfg: Precision Reflex, Inc. SPECS: Aluminum, natural silver, and matte black anodized finish.
