Running a magnified optic on your AR is great until you need to hit something up close and fast. That's where the XS Sights XTI2 DXS Ember set earns its keep. Mounted at a 45 degree offset, these back-up iron sights let you roll the rifle a few degrees and pick up a fresh sight picture in an instant, no dialing magnification down and no fumbling. The front sight runs a 0.140 inch wide post capped with an Orange Ember Glow Dot that reads high-contrast in bright light and charges off the sun's UV rays to glow in shadows, vehicle interiors, and other low-light spots.
This is the second-generation XTI design, and the updates matter. The bases sit taller than the originals, which means you keep a standard cheek weld while lining up the sights instead of mashing your face into the stock. XS also opened up the base angle to clear the wider lenses and bells found on today's LPVOs and prism optics. The straight-line express sight picture is built for speed, making this a favorite pairing for 3-gun stages where you're moving through vehicles and awkward positions with backlighting working against you.
The sight set weighs in around 2.02 ounces thanks to 6061 T6 aluminum bases and CNC steel iron sights, so you get duty-grade toughness without loading down your handguard. Everything is fully ambidextrous too, since the front and rear can be rotated for lefty shooters. Installation is a straightforward top-rail bolt-on that fits optic-ready AR-15s, and XS recommends spacing the sights as far apart on the rail as you can to stretch out that sight radius. The rear sight ships driftable for easy windage, so you can zero first and lock it down with the included thread locker afterward.
No, this DXS Ember set is the non-tritium version. The front dot is a photoluminescent Orange Ember Glow Dot that charges from ambient UV and sunlight, giving you a bright high-contrast aiming point in daylight and a glow in shadows or low-light spots. If you want a front sight that glows on its own in total darkness, XS offers a tritium DXT version of this sight.
Yes. XS increased the base angle on this second-generation design specifically to clear wider lenses and larger optic bells, and the taller bases let you keep a standard cheek weld when you roll the rifle. They bolt onto any optic-ready AR-15 top rail, and it's best to space them as far apart on the handguard as possible for a longer sight radius.
The rear sight ships installed but not sealed to the base so you can drift it for windage. Get your rifle zeroed first, then apply the included thread locker to lock everything in place. The front sight tool included in the box handles elevation adjustments.
They're a strong fit for it. The straight-line express sight picture is built for rapid acquisition at close range, and the Ember dot shines in the varied lighting you run into during matches, from bright outdoor stages to shooting from vehicles. Mounting them ahead of your primary optic also helps keep gear from snagging on chest rigs.
