RS Regulate Trijicon MRO Modular Upper, Black Matte Finish

In the realm of firearm accessories, precision and adaptability reign supreme. RS Regulate brings forth a masterstroke with their AK-300 Modular Side Mount System, a testament to innovation that has been evolving since its inception in 2012. This modular system is not merely an accessory; it is an enhancement that transforms your rifle into a more versatile tool.

At the heart of this system lies its fully customizable nature, boasting six distinct modular uppers paired with nine diverse lowers. Each component is crafted for compatibility and operational excellence across various platforms. The design caters to Eastern European AK side rails with options including front-biased, rear-biased, and full-length lowers ensuring optimal fitment and performance.

For those wielding Yugo or Serbian rifles, RS Regulate offers both front-biased and full-length lower variants tailored specifically for these models' unique specifications. Not stopping there, they extend their ingenuity to accommodate PSLs alongside Romanian M10/RH10 rifles—demonstrating respect for diversity in firearm architecture.

Understanding the needs of American enthusiasts as well, there's provision made for Century Arms’ proprietary side rail systems. Even owners of Czech vz. 58s find themselves accounted for with dedicated rear-biased lower mounts designed explicitly for such distinctive firearms.

With each piece engineered meticulously from robust materials meant to withstand rigorous use without compromising on alignment or stability during operations—RS Regulate’s AK-300 series stands as an embodiment of reliability combined seamlessly with adaptability.
