XS Sight XTI2 DXW 45 Degree Offset BUIS Tritium Front / Non-Tritium Rear Review

First Thoughts on the XS Sight XTI2 DXW 45 Degree Offset BUIS Tritium Front / Non-Tritium Rear

The XS Sight XTI2 DXW 45 Degree Offset BUIS Tritium Front / Non-Tritium Rear offers a rapid transition sighting solution for AR-15 platforms. This setup promises reliable backup iron sights that are easily accessible when primary optics fail or are unsuitable for close-quarters engagements. I was particularly interested in the tritium front sight for its potential to improve target acquisition in low-light conditions, something often lacking in standard backup iron sights.

As a tactical gear specialist, I’ve been searching for a reliable and intuitive offset BUIS system for my AR-15. My primary optic is fantastic for medium to long-range engagements, but becomes cumbersome and slow to acquire targets within 25 yards. I wanted something that would allow me to quickly transition to a close-quarters sighting system without sacrificing accuracy or reliability.

The XS Sight system arrived in a no-frills package, but the sights themselves felt substantial and well-made upon unboxing. The 6061 T6 aluminum bases seemed robust, and the CNC steel sights themselves displayed a clean, durable finish. The tritium lamp in the front sight provided a noticeable glow, even in dimly lit environments.

I considered other offset BUIS options from Magpul and Midwest Industries, but ultimately chose the XS Sight system due to the tritium front sight and the “Dot-the-‘i'” sight picture. Magpul’s polymer sights felt less durable, and while the Midwest Industries option was appealing, the XS Sight’s emphasis on low-light visibility sealed the deal. My initial impression was positive; I was eager to test its performance in various conditions.

Real-World Testing: Putting XS Sight XTI2 DXW 45 Degree Offset BUIS Tritium Front / Non-Tritium Rear to the Test

First Use Experience

My first experience with the XS Sight XTI2 DXW 45 Degree Offset BUIS Tritium Front / Non-Tritium Rear was at an indoor shooting range. I focused on transitioning between my primary red dot optic and the offset iron sights at distances ranging from 7 to 25 yards. The transition was surprisingly smooth and intuitive after a few practice runs.

I also tested the sights in low-light conditions within the range, simulating a potential home defense scenario. The tritium front sight stood out brilliantly, allowing for quick and accurate target acquisition. There were no initial issues; the sights held zero after several magazine changes and felt solid throughout the session.

Extended Use & Reliability

After several months of use, including multiple range trips and a tactical training course, the XS Sight system has proven to be remarkably durable. The finish shows minimal signs of wear, even after exposure to dirt, mud, and light rain. The sights remained securely mounted and retained their zero throughout.

Maintenance is straightforward. A simple wipe down with a lightly oiled cloth is all that’s needed to keep the sights clean and functioning optimally. Comparing this to some polymer sights I’ve used previously, the XS Sight system’s durability and reliability far exceed my expectations.
