The RS Regulate RS REG TRIJICON RMR MODULAR UPPER is a precision optics mounting solution designed to streamline integration of Trijicon RMR and Holosun HS507C sights on a Picatinny rail, delivering a robust, matte black, optic-specific upper that enhances alignment and repeatability. Built by RS Regulate, this modular upper leverages a Picatinny mounting interface to provide a secure, low-profile platform that maintains proper clearance and zero cues for fast target acquisition. With a matte finish and black color, it complements tactical, competition, and precision setups while preserving the integrity of the rifles silhouette. The Modular Upper is engineered to fit Trijicon RMR patterns with compatibility aimed at reliable alignment under recoil, ensuring repeatable sight picture during rapid fire and precision shots alike. As a purpose-built optic mounting solution, it integrates seamlessly into systems seeking a dedicated optic upper that supports consistent mounting surfaces and optical height, reducing drift and maintaining accuracy across hard-use scenarios. This RS Regulate offering is ideal for shooters who value a purpose-built, optic-specific upper that simplifies assembly, maximizes robustness, and sustains consistent performance with compatible RMR and HS507C optics.
