Product Description

The XS Backup Sight, XTI2 is the premier close-quarters, secondary sighting solution for a fast sight transition from a magnified primary optic. XTI2 sights reduce target engagement time and eliminate magnification adjustment, making it the better option off the bat.

Highly visible white for bright and low light shooting XTI2 sights ship with thread locker and a front sight adjustment tool. The rear sight is installed, but not sealed to the base to allow for easy windage adjustment. Thread locker will need to be applied after the rifle is zeroed.

Top Performance in Any Environment

Designed to perform in any environment, XTI2 sights are an all-weather operator. From high heat to freezing cold conditions, our sights are reliable. The XTI2 45 BUIS is practical whether you're a competitive shooter or a tactical operator. The tritium illumination provides visibility in total darkness, while the functional construction prevents accumulation of dust, dirt, and moisture. Our sights are designed with versatility in mind, fitting a wide range of models and ensuring you have the right setup for any situation.

XTI2 express 45 degree sights are ideal for 3 gun competitions. Most matches take place during the day and have stages in vehicles and other settings that reduce ambient light or present backlighting issues. Our design provides a visible front sight in bright light and a tritium glow in low light settings.

XTI2 backup iron sight sets are mounted in front of the optic to reduce snagging gear on chest rigs. 3-gun matches are effective from short to long distances. XTI2 sights are pistol sights designed for pistol length distances where magnified optics make target identification more difficult.

Variations of our XTI2 45° Offset BUIS

The XTI was originally a wide shallow V rear sight with a front sight has evolved into the version we know today – the XTI2 45. Coming in both standard dot and big dot variations, this sight provides handgun users the best possible sight picture across lighting conditions. Many users prefer the Big Dot sight picture because it is flat-out hard to miss, but it all comes down to personal preference. We even have an orange ember non-tritium option if that is what you prefer!
