The XS SightXTI2 DXT 45-Degree Offset Back-Up Iron Sight Set (brand part no. AR-0008-5) from XS Sights bolts onto any optic-ready AR-15 top rail and rotates 45 degrees off-axis for instant use behind a primary optic. Unlike the DXW version, this DXT set runs tritium in both the oversized Big Dot front and the V-notch rear, giving true low-light capability at both ends of the sight picture. Both sights ride on 6061 T6 aluminum bases to keep weight off the rifle, and CNC-machined steel construction keeps them duty-durable through hard use.
