XS XTI2 sights are a 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. Our second generation XTI’s feature taller bases for easy sight alignment, without having to break a standard cheek weld. Additionally, the base angle has been increased to accommodate wider lens optics. The front sight measures 0.188" for a big dot and 0.140" wide for a standard dot and feature a White Big Dot with a Tritium center. The straight-line express sight picture makes XTI2's ideal for rapid sight acquisition and close target shooting. 

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 base to allow for easy windage adjustment. Thread locker will need to be applied after the rifle is zeroed.

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

    Best in the Business-From Experience

    I run a KENU riser + EXPS-3 and Aimpoint 3x Mag, Removing traditional irons capability. I've tried other offset options, but the issue going from illuminated sight picture to offset flat SP took an impractical acquisition time. XS BOIG DOT BUIS changed that. The size, color, and tritium of the front dot is an easy, quick transition; a must have in my scenario.

    good sights

    Got these for my ruger charger as a back up to the dot sight. They are excellent sights and would buy them again if needed.
