Xs Sightxti2 Dxt 45 Degree Offset Buis Tritium Front & Rear
The XS Sights SightXT I2 DXT 45-degree offset BUIS delivers a true backup iron sight system built for shooters who run optics on modern AR-15s. These tritium-powered iron sights mount perpendicular to your rifle's picatinny rail—keeping your primary optic unobstructed while giving you a fast, reliable aiming solution when you need it. The offset angle positions the front and rear sights clear of most magnified scopes and red dots, so you get a functional sighting system without compromise.
What sets the SightXT I2 apart is its thoughtful sight picture: the tritium-lit front post pairs with a low-profile V-notch rear for a clean, differentiated sight alignment that works in daylight and dim conditions alike. The rear sight features a white stripe option (or tritium bar, depending on your configuration) to help you find the proper sight picture fast under pressure. Windage adjustment on the rear sight means you can dial in accuracy without gunsmithing, and the whole setup tips the scales at just over 2 ounces—minimal penalty for maximum utility. Both sights rotate for left-handed shooters, making the system truly ambidextrous.
Built from CNC-machined steel and aluminum (6061 T6 bases), these sights are engineered to handle duty use and field conditions. Installation is straightforward: they bolt directly to any optic-ready AR-15 top rail. Whether you're setting up a duty rifle, a hunting carbine with a scope, or an everyday defensive AR, the SightXT I2 DXT offers the reliability and accuracy of a fixed iron sight system without the bulk or weight.
