RS Regulate AK-300 Side Mount Full-Length Modular Lower for AKM Rails, lightweight aluminum AK-303M

Product Description

The RS Regulate AK-303M is the full-length modular lower for the AK-300 Side Mount System, engineered to mount to standard AKM-pattern side rails and serve as the foundation for RS Regulate upper optic mounts. Designed for Eastern European AK side rails, this lower offers a stable, low-profile base that keeps your rifle slim while enabling precise optic placement once paired with the appropriate RS upper. It is an example configuration for Russian and Bulgarian AKM pattern side rails and requires an RS Regulate upper mount to attach optics. Note: this lower is not compatible with the VEPR or FIME Vepr-FM rifles with factory folding stocks.
