RS Regulate Modular Upper for Trijicon RMR and Holosun HS507C

In 2012, RS Regulate introduced the AK-300 Modular Side Mount System, a game-changer for AK enthusiasts and professionals alike. This system stands as a testament to innovation in firearms accessories, offering unparalleled adaptability and precision.

The AK-300 Series is engineered with six fully modular uppers paired with nine distinct lower mounts. These combinations cater to a wide array of Eastern European rifles including front-biased, rear-biased, and full-length lowers specifically designed for various models. Whether you are outfitting most Eastern European side rails or specific models like Yugo/Serbian rifles or PSLs, this system provides solutions tailored to your needs.

Notably versatile options include lowers compatible with Romanian M10/RH10 rifles and Century Arms' proprietary side rail systems. For those wielding Czech vz. 58s, there's even a dedicated rear-biased lower mount available.

Each component of the AK-300 System is crafted to ensure secure attachment while maintaining ease of use when mounting optics on your firearm. This design philosophy ensures that shooters can achieve optimal accuracy without compromising their weapon’s balance or ergonomics.

With RS Regulate's commitment to quality and performance at its core, the AK-300 Modular Side Mount System remains an essential upgrade for any serious shooter looking to enhance their rifle's capability.
