The Shadow Systems U526 5.56mm 16" TB MLOK Blk/Blk 10-Rd is a purpose-built duty rifle designed for shooters who demand smooth recoil, consistent performance, and long-term reliability. Its 16-inch threaded barrel with a 1:7" twist works in concert with an intermediate gas system and Maelstrom flash hider to deliver a refined shooting impulse across a wide range of 5.56 NATO ammunition. A rigid M-LOK handguard interface and proprietary furniture system provide a stable, comfortable platform for modern accessories and confident handling.

This semi-automatic rifle’s two-stage duty trigger, DLC-coated bolt carrier group, and 10+1 capacity make it well suited for range work, training, and patrol-style roles where predictable control and durability matter. The collapsible stock allows shooters to tailor length of pull, while the black nitride finish supports corrosion resistance and easy maintenance. With its cohesive set of proprietary components, the U526 reflects Shadow Systems’ focus on thoughtful engineering and dependable craftsmanship.
