Rs Reg Full-length Yugo Modular Lwr

The RS Regulate Reg Full-Length Yugo Modular Lower is a precision-engineered mounting component for Yugo and Serbian AK-pattern rifles, designed to integrate with RS Regulate's modular AK-300 side-mount system. This full-length lower receiver extension provides a stable, repeatable platform for optics mounting on rifles with side-rail configurations common to Yugoslav-manufactured platforms. The full-length geometry distributes mounting forces across the entire receiver length, enhancing rigidity and reducing point-load stress on the side rail—critical for accuracy-demanding applications from intermediate distances to longer ranges.

Weighing just 0.31 pounds, this modular lower maintains minimal weight penalty while the compact profile (7.75 inches in length, 1.25 inches in width) ensures it does not obstruct charging handles or limit side-access ergonomics. The modular design integrates seamlessly with any of RS Regulate's AK-300 upper receivers, allowing operators to swap optics platforms, magnification levels, or mounting angles without replacing the lower—a practical advantage for shooters who cycle between multiple rifle configurations or training scenarios. Built to the exacting tolerances RS Regulate is known for in the AK platform community, this lower is engineered to maintain zero through repeated mounting cycles and field use.

This component is purpose-built for Yugo-platform AK owners seeking a genuinely modular mounting solution that avoids the compromises of permanent gunsmithing. Whether for patrol rifles, training systems, or precision-oriented builds, the full-length lower is the foundation for a modern optic setup on rifles that historically lacked quality mounting options. Compatibility is specific to Yugo and Serbian side rails—verify your rifle's rail type before purchase to ensure proper fit.

RS Regulate's AK-300 system has become the standard-bearer for side-mount reliability in the professional and enthusiast AK community, with both military and law-enforcement adoption due to its repeatable accuracy and minimal point-of-impact shift. The full-length lower option addresses the specific needs of Yugo owners previously limited to improvised or single-purpose mounting solutions.
