XS Sights XTI2 DXT 45 Degree Offset BUIS Tritium Front & Rear

Description

The XS Sights XTI2 DXT is a 45 degree offset back-up iron sight (BUIS) set designed to provide a clear secondary sighting option for optic-ready AR-style rifles. Both front and rear sights include tritium illumination and a contrasting white Big Dot for improved visibility across light conditions. The rear sight uses a low-profile V-notch and is driftable for windage adjustment while the bases are machined from 6061 T6 aluminum to minimize added weight.
