The Shadow Systems U526 5.56mm 16" TB M-LOK Blk/Brnz 10-Round rifle is a purpose-built duty carbine designed for shooters who demand smooth recoil and consistent performance. Its 16" chrome-lined, hybrid-profile threaded barrel is paired with an intermediate gas system and Maelstrom flash hider, delivering a refined shooting impulse across a wide range of 5.56 NATO ammunition. A rigid M-LOK handguard interface, bronze-finished bolt carrier group, and proprietary furniture, rail, trigger, and controls create a cohesive, predictable platform from the first shot to the last.

This semi-automatic rifle’s two-stage duty trigger, collapsible stock, and ergonomic grips make it well suited for serious training, home protection, and extended range sessions where reliability and comfort matter. The 10+1 capacity configuration is ideal for jurisdictions with magazine restrictions while still offering modern AR-15 handling and modularity. Shadow Systems’ attention to detail, engineering, and craftsmanship is evident throughout the U526, resulting in a refined, dependable rifle built for long-term use.
