The Shadow Systems U526 5.56mm 16" TB MLOK FDE/Blk 10-rd is a semi-automatic duty rifle built around a 16-inch threaded barrel and a rigid M-LOK handguard. Its intermediate gas system, hybrid-profile chrome-lined barrel, and Maelstrom flash hider are designed to deliver a smooth, consistent recoil impulse with dependable performance across a wide range of ammunition. Proprietary furniture, a DLC-coated bolt carrier group, and a two-stage duty trigger round out a cohesive, refined AR-pattern platform.

This configuration pairs a Flat Dark Earth finish with black accents and ships with a 10-round magazine, making it suitable for jurisdictions with capacity limits as well as shooters who prefer a lighter, streamlined setup for training and general-purpose range work. The collapsible/folding stock and ergonomic grip support comfortable handling, while the threaded muzzle is ready for brakes or suppressor-ready accessories. Shadow Systems’ attention to detail and focus on reliability are evident throughout the U526 rifle.
