The folding hinge components are constructed of steel with a Melonite finish for an extremely rugged and durable surface. The folding hinge interface is designed to ensure a positive lock and removes any potential for hinge movement, even after numerous cycles and under the heaviest of recoil. The hinge push-button is serrated to ensure proper purchase during activation and is recessed into the hinge body to mitigate accidental actuation. The rigid spring and hardened detent ensure the folding component is captured securely when folded. The large dovetails provide a rigid mounting interface between the stock and chassis body to ensure a solid union of both and removes any play between the two parts for a consistent and repeatable foundation paramount to the demands of a precision shooter.
