Shield Sights SIS2 Features The Shield Sights SIS2 builds on the military proven CQB/CQS red dot platform with a switchable interface that lets the shooter select from four reticle options 8 MOA dot 8 MOA dot with a 65 MOA ring 2 MOA dot and 2 MOA dot with a 65 MOA ring all without ever losing zero. A large crystal clear lens with no filters keeps the world beyond the glass undistorted important for fast target transitions and situational awareness. The sight is machined from aerospace grade aluminum to tight tolerances delivering a rugged housing that still carries a modern streamlined profile. Developed with feedback from Special Forces Law Enforcement and Military users the SIS2 is engineered to perform under exactly the conditions that demand absolute reliability. Brightness control on the SIS2 combines 12 stage manual adjustment including three night vision settings with 3 stage automatic brightness adjustment so the reticle stays visible whether the shooter is indoors outdoors or moving between the two. An intelligent on and off function remembers the previous brightness setting so the sight returns to exactly where the user left it rather than resetting to a default. At just 2.15 ounces and rated for up to 20 000 hours on a single CR2032 battery the SIS2 adds negligible weight to a duty or competition pistol while running for years of ordinary use. Nitrogen sealed and submersible to 30 feet for 30 minutes the Shield Sights SIS2 mounts to any Picatinny fitted weapon and ships with a 3 stage mount for adjustable height making it a dependable reflex sight for sale at GrabAGun.
