The Shadow Systems U526 (brand part no. SS-6012) is a semi-automatic AR-15 pattern rifle chambered in 5.56 NATO / .223 Remington, built by Shadow Systems as the company’s first rifle platform after years of building pistols. A 16-inch barrel with a 1:7 twist rate handles the full range of 5.56 bullet weights, and an ambidextrous safety selector gives right- and left-handed shooters the same control. It’s built as a duty-ready rifle for shooters who already trust Shadow Systems’ fit and finish on their pistols. This U526 configuration favors range shooters and home-defense buyers who want a 16-inch 5.56 rifle from a maker known for tight tolerances.
