The Shadow Systems U526 (brand part no. SS-6052) is a 5.56 NATO rifle built around a 16-inch barrel, bringing the machining-driven refinement Shadow Systems built its pistol reputation on to a full-size carbine platform. The 1:7 twist rate stabilizes the full range of 5.56 bullet weights, and this configuration pairs a Flat Dark Earth and black two-tone finish with a 10+1 capacity. At roughly 6.2 pounds, the U526 stays light enough for training days and defensive use alike, and a standard safety selector keeps the manual of arms familiar to any AR shooter. For shooters who already trust Shadow Systems pistols, the U526 extends that same performance-focused approach to a duty-grade rifle.
