The Shadow Systems U526 FDE Rifle 5.56mm 16" Barrel Maelstrom Plan B DLC BCG is a purpose-built duty rifle designed as a complete system rather than a parts-bin build. Its intermediate gas system, hybrid-profile 16" 4150 CMV barrel, and Maelstrom flash hider work together to deliver a smooth, predictable recoil impulse across a wide range of 5.56 NATO and .223 Remington ammunition. A DLC-coated bolt carrier group, pinned gas block, and two-stage duty trigger underscore the rifle’s focus on long-term reliability and consistent performance.

This U526 configuration features a flat dark earth finish with duty-focused furniture, a collapsible stock, and a lightweight M-LOK handguard that offers ample mounting space while keeping the rifle nimble. With a 30-round capacity and overall length of 32.5", it is well suited for training, range use, and practical competition where control and durability matter. Shadow Systems’ reputation for thoughtful engineering and meticulous assembly is evident in the U526, delivering a refined shooting experience for demanding shooters.
