RS Regulate Full-Length Yugo Modular Lower Mount – AK-307MS Pattern Rail

The RS Regulate Full-Length Yugo Modular Lower Mount is a precision-machined base rail designed specifically for Yugoslavian-pattern AK rifles with the AK-307MS side rail configuration. This lower mount serves as the foundation for RS Regulate's modular optic mounting system, replacing the factory side rail with a rigid, repeatable platform that maintains zero through repeated removal and reinstallation.

Machined from 6061-T6 aluminum with a hard-anodized finish, this full-length lower mount provides maximum rigidity and extends the mounting surface for improved stability with heavier optics or night vision setups. Installation requires no gunsmithing—the mount replaces the factory rail using the existing attachment points. Compatible with all RS Regulate upper mounts, allowing shooters to configure red dots, magnified optics, or combination setups to their specific needs.
