5x5 Adapter Plate Rear End Fixture (Each)

The 5x5 Adapter Plate Rear End Fixture is a precision mounting solution designed for chassis systems, precision rifle builds, and rear-end component integration where dual 5-inch bolt pattern compatibility is required. This adapter plate bridges different mounting interfaces, enabling seamless integration of rear-end assemblies and accessory systems that operate on standard 5-inch hole spacing. It is essential for builders and armorsmiths who need to standardize mounting between components with non-matching bolt patterns or to simplify inventory management across multiple platform builds.

Manufactured from anodized aluminum and finished in a durable black anodize coating, this adapter plate delivers lightweight strength while resisting corrosion and wear in field and workshop environments. The 5x5 bolt pattern design accommodates standard mounting fasteners at precisely spaced intervals, ensuring load distribution and repeatable, secure attachment. Aluminum construction minimizes overall system weight—critical for long-range platforms and tactical systems—while maintaining the rigidity required for precision applications. The black anodized finish provides professional aesthetics and functional corrosion protection that withstands moisture, solvents, and repeated handling.

This fixture is ideal for gunsmiths, precision rifle builders, and military/law enforcement armorsmiths standardizing rear-end mounting systems across equipment platforms. Its compact dimensions (12.2 x 4.8 x 12.3 inches) allow installation in confined chassis mounting points without adding bulk. Proper installation requires compatible fasteners (not included) matched to your specific bolt holes; torque specifications should follow manufacturer guidelines for your complete system. Whether upgrading legacy systems, building modular platforms, or simplifying multi-caliber rear-end swaps, this adapter plate serves as a reliable, repeatable mounting interface.
