The RS Regulate AK-307MS Yugo Full-Length Lower is designed for Yugo/Serbian Type Rifles (OPAP, NPAP or M21 pattern rifles) and serves as a foundational component of the RS Regulate AK-300 Modular Side Mount System. These mounts feature a unique titanium-based low profile locking system which does not protrude from the side of the mount and does not interfere with the trigger guard area, ensuring that once the mount is locked in place, your rifle will stay zeroed. It is made from 6061-T6 aluminum and the modular design allows you to center your optic over the bore and set proper eye relief.
The AK-307MS measures 5.71 x 0.55 x 1.88 inches and weighs 3.37 oz, making it an exceptionally lightweight addition to your rifle. The full length rail option allows for the widest range of adjustment, so you can get proper eye relief with almost any optic. The 307MS is the upgraded version of the 307M featuring a user replaceable steel recoil lug, allowing for easy maintenance and replacement if needed. An upper optic mount must be added to use your optic, giving you the flexibility to tailor your system to your specific sight requirements.
