XS Sights XTI2 DXS Ember 45 degree Offset BUIS for AR-15

XS Sights XTI2 DXS Ember sights provide a 45 degree offset back-up iron sight (BUIS) solution for AR-15 platforms, intended for fast transitions from a magnified primary optic. The set features taller bases to preserve a standard cheek weld while accommodating wider optics and lens profiles. The front sight includes an Orange Ember photoluminescent glow dot that charges from ambient UV for high contrast in bright conditions and visible charge in low-light shadows. Built with aluminum bases and CNC steel sight components, the set is designed for practical close-quarters and competition use where a rapid, reliable secondary sight is required.
