Shadow Systems E526 Features The Shadow Systems E526 runs on a semi-auto action chambered in 5.56 x 45mm paired with an 11.5 spiral fluted barrel that sheds weight while helping dissipate heat during extended strings of fire. The 1-in-7 rate of twist stabilizes a wide range of 5.56 bullet weights giving shooters flexibility in ammunition selection without sacrificing accuracy. A threaded 1/2x28 muzzle accepts the factory device or an aftermarket compensator or suppressor and the special feature designation confirms the barrel is ready to accept one out of the box. The 30 plus 1 capacity supported by two included 30-round magazines keeps the gun fed through demanding range sessions or defensive scenarios. The proprietary furniture system includes a collapsible and folding stock that shrinks the overall footprint for storage and transport without tools. A 60 to 90 degree thumb safety gives the shooter a positive easily indexed control under stress and the Black Nitride finish resists wear and corrosion through hard use. At 5.4 lbs the rifle stays maneuverable in tight spaces while still feeling solid in hand. Shipped in a dedicated SS rifle bag the Shadow Systems E526 is built for shooters who want a compact short barrel 5.56 platform ready for serious use for sale at GrabAGun.
