Designed in conjunction with Solomon; a Short Action Customs team shooter, the Solo-Loc Ring is designed to make setting up and running your Forster Co-Ax press easier, faster, and more precise. The new design prevents the reloading die from spinning or turning in the press while making adjustments. The "Solo-Loc" can be easily adjusted without needing to remove the reloading die from the press by simply tightening or loosening the 8/32 lock screw. It Includes laser engraved adjustments marks in 0.002" increments for precise adjustments. Precision machined from 6061 high strength aluminum. Type 3 Hard Coat Anodized.
