Description
When you're running a magnified optic on an AR and need a quick close-range option, the XS Sights XTI2 DXT gives you a clean secondary sight picture without pulling your scope. Mounted at a 45 degree angle on the top rail, these sights sit ready to go with a simple rotation of the rifle. That means no fumbling with magnification and no losing your cheek weld when a target pops up close.
The front sight is the star here. It's a high-contrast white Big Dot measuring 0.188 inches wide with a tritium center, so it grabs your eye in daylight and glows in shadows, vehicles, or full darkness. Pair it with the low-profile V-notch rear and you get the classic XS straight-line "dot-the-i" picture: center the dot over the vertical bar and you're aligned. It's the kind of sight setup that's flat-out hard to miss with, which is exactly what you want when the clock is running or the light is bad.
What Makes the XTI2 DXT Different
This is the second-generation XTI design. XS raised the bases and increased the base angle so the sights clear wider-lens optics and stay easy to pick up without contorting your head. The rear sight is driftable for windage, and it ships installed but not sealed so you can zero it first, then lock it in with the included thread locker. The rifle's ejection port stays clear during use, and the whole setup is reversible for left-handed shooters.
Built to Take a Beating
The iron sights are CNC-machined steel for duty-grade toughness, sitting on lightweight 6061 T6 aluminum bases that keep the added weight down around two ounces. Everything is made in Fort Worth, Texas, and backed by the XS no-questions-asked lifetime sight warranty. Whether you're building out a 3-gun rig or setting up a serious-use carbine, the XTI2 DXT is a bolt-on upgrade that just works.

Frequently Asked Questions
How do the XTI2 DXT offset sights work with my scope still mounted?
They mount on the top rail at a 45 degree angle, so your primary optic stays right where it is. When a close target shows up, you just rotate the rifle roughly 45 degrees to bring the irons upright and align on target. There's no need to remove the scope or dial down magnification, and you keep your cheek weld the whole time.
Will the XTI2 DXT clear a wide-lens optic and the ejection port?
Yes. This second-generation design uses taller bases and an increased base angle specifically to accommodate wider-lens optics while keeping the sights easy to pick up. Mounting the XTI2 also doesn't interfere with the ejection port or normal function of the rifle.
How do I zero the rear sight on the XTI2 DXT?
The rear sight is driftable for windage and ships installed but not sealed to the base, so you can adjust it freely while zeroing. Once you're dialed in, apply the included thread locker to lock everything in place. The kit also comes with a small tool for front sight adjustment.
Are these sights good for left-handed shooters?
They are. Both the front and rear sights are fully ambidextrous and can be rotated for left-handed use. A right-handed shooter rolls the rifle one way to deploy them, and a lefty simply sets them up to rotate the other direction.
