Forster Products Quick Change Jaws "LS" LG

The Forster Products Quick Change Jaws "LS" LG is a precision-engineered jaw assembly designed for the Forster Co-Ax reloading press, enabling shooters to swap cartridge case-holding components without complete press reconfiguration. These spring-loaded jaws contact the base of the cartridge cannelure for secure case positioning during both sizing and seating operations, then automatically release when the press handle is raised—streamlining the reload cycle for handloaders managing multiple calibers or case types.

The self-acting jaw mechanism eliminates manual case manipulation between strokes. When the press handle descends, the jaws automatically seat around the cartridge case; when lifted, they open and release without operator intervention. This design reduces fatigue during high-volume reloading sessions and minimizes the risk of case damage from improper extraction. The "LS" (Large Single) designation indicates this jaw set is sized for larger cartridge case bases and replaces only one side of the press, allowing users to retain their existing opposing jaw assembly while upgrading or changing configurations.

Serious handloaders processing magnum rifle cases, large pistol rounds, or managing a diverse cartridge library benefit from quick-change jaw systems. This assembly is ideal for reloaders who frequently switch between calibers and cannot justify the downtime of full press disassembly. Competitive shooters, high-volume hunters, and precision rifle enthusiasts who maintain strict case integrity standards will appreciate the consistent, non-marring grip the Co-Ax jaw design provides.

Forster Products has established itself as a manufacturer of benchrest-grade reloading equipment, and the Co-Ax press platform remains an industry standard for accuracy-focused handloaders. Quick-change jaw systems represent a significant efficiency gain for shops or individuals processing mixed-caliber batches, reducing setup time while maintaining the case concentricity that the Co-Ax platform is known for.
