Shadow Systems U526 Features The Shadow Systems U526 is built around an intermediate gas system paired with a hybrid profile chrome lined 4150 CMV barrel a combination designed to deliver a smooth consistent shooting impulse across a wide range of 5.56 NATO and .223 Remington ammunition. The 16 inch barrel features spiral fluting to reduce weight while maintaining strength and is threaded 1/2x28 with a pinned gas block to accept the rifle s Maelstrom flash hider. A two stage duty trigger gives shooters a crisp predictable break suited to both precision shot placement and rapid follow up shots.

Proprietary furniture throughout the rifle including the rail trigger and controls ensures predictable performance from the first shot to the last. The M-LOK handguard interface provides a rigid platform for mounting accessories under recoil while the Picatinny top rail on the Flat Dark Earth receiver gives shooters a direct mounting surface for red dots or magnified optics. Feeding from a 10 round CompMag the U526 ships with a 60 to 90 degree thumb safety for intuitive manual operation. At 6.45 pounds and 32.5 inches overall this CA compliant configuration gives shooters in restricted states access to the same duty focused U526 platform built for smooth recoil and long term reliability.
