The Shadow Systems U526 5.56 Rifle (Model SS-6011) is a purpose-built duty carbine designed for shooters who demand smooth recoil and consistent performance. Its 16" chrome-lined, hybrid-profile barrel is paired with an intermediate gas system and Maelstrom flash hider to deliver a refined shooting impulse across a wide range of ammunition. A rigid M-LOK handguard interface, AR-style receiver with Picatinny rail, and proprietary furniture, trigger, and controls create a cohesive platform focused on reliability and predictable handling.

This U526 configuration in Black/Bronze is well suited for range use, training, and general defensive applications where accuracy and controllability matter. The two-stage trigger supports precise shot placement, while the polymer stock and grip offer comfortable ergonomics for extended sessions. With its 5.56 NATO chambering, 16" barrel, and modern AR-style layout, the rifle provides a versatile foundation for optics and accessories. Shadow Systems’ reputation for thoughtful engineering and durable construction is evident throughout this model.
