Xs Sightxti2 Dxw 45 Degree Offset Buis Tritium Front / Non-Tritium Rear

The XS Sights SightXTI2 DXW 45 Degree Offset BUIS is a backup iron sight set built for shooters who run an optic but need redundancy without compromise. The tritium-powered front sight glows in low light—no battery required—while the non-tritium rear sight keeps things simple and lightweight. This combo sits at a 45-degree angle to your rail, staying out of your optic's way but instantly ready if your primary goes down. At just over 2 ounces, it adds virtually nothing to your AR platform while giving you a rock-solid sight picture you can count on.

The sight picture is engineered around the "dot-the-i" principle: your tritium front post lines up dead center in the V-notch rear, creating a straight and intuitive sight alignment. The rear sight V-notch is kept deliberately low-profile so you maintain clear visibility downrange—exactly what you want in a fast-moving scenario. Windage is user-adjustable via a simple drift on the rear sight, so zeroing doesn't require a gunsmith visit. Both front and rear can be rotated for left-handed shooters, making this a genuinely ambidextrous setup.

Built from CNC-cut steel and aluminum (6061 T6 bases), these sights are built to handle duty use and won't flex or fail when you need them. Installation is straightforward: bolt onto any optic-ready AR-15 top rail, and you're done. No special tools, no permanent modifications.

Frequently Asked Questions

What AR-15 platforms are these sights compatible with?

The SightXTI2 DXW is designed to fit any optic-ready AR-15 rifle with a standard top rail. Installation is a simple bolt-on with no modifications needed.

Can I use these sights with a mounted optic?

Yes—that's the whole point. The 45-degree offset mounting keeps them clear of your primary optic, so they function as true backup irons. You can deploy them quickly if your optic fails or is removed.

Does the rear sight have tritium, or just the front?

The front sight is tritium-powered for low-light visibility; the rear sight is non-tritium. This setup keeps the rear sight simpler and lighter while maintaining a glowing front reference for aiming in darkness.

Are these sights ambidextrous?

Yes. Both the front and rear sights can be rotated to accommodate left-handed shooters, making this a fully ambidextrous backup sight system.
