Rs Reg 30mm Modular Ring Upper

The RS Regulate 30mm Modular Ring Upper is the top component of RS Regulate's AK-300 Modular Side Mount System, purpose-built for precision rifle optics mounting on Eastern European AK variants. This upper ring accepts standard 30mm scope rings and interfaces with any RS Regulate lower receiver, enabling shooters to run modern tactical optics on AK platforms that traditionally lacked reliable mounting solutions. The modular architecture—introduced in 2012—makes this upper compatible with nine different lower configurations, covering the widest range of AK variants on the market.

Machined for precision and repeatability, the 30mm upper ring accepts any standard 30mm scope ring with sufficient clearance, allowing shooters to pair it with industry-standard optics from premium manufacturers. At 0.19 lbs and engineered in compact dimensions, this upper adds negligible weight while maintaining rigid geometry under recoil. The modular design means users can source the appropriate lower receiver for their specific AK platform—front-biased or rear-biased configurations for standard side rails, dedicated setups for Yugo/Serbian rifles, PSL rifles, Romanian M10/RH10 models, Century Arms proprietary rails, or Czech vz. 58 platforms—then pair it with this universal upper for a complete system tailored to their rifle.

This upper ring serves competitive shooters, designated marksmen, and tactical operators running quality optics on AK-pattern rifles. It solves the engineering challenge of mounting 30mm scopes securely to a side rail without compromise to zero retention or repeatability. The modular system approach eliminates guesswork: operators identify their specific AK variant, select the corresponding lower, then use this upper across multiple rifles if needed, reducing redundancy in tactical arsenals.

RS Regulate's AK-300 system represents the industry standard for AK side-rail optics mounting, developed specifically to address precision rifle requirements on platforms where traditional pic rail systems are incompatible. This 30mm upper ring is the foundation component; quality and consistency in this part directly impact zero stability and target accuracy downrange. Operators who demand accuracy beyond iron sights—whether for training, competition, or duty use—rely on systems like this to bridge the gap between AK ergonomics and modern optics technology.
