XS Sight Systems has expanded its Xpress Threat Interdiction line for AR-15 rifles with the Big Dot Tritium Express and the 24/7 Tritium Angle Mount Back-Up sights.

Designed for firearms equipped with handguard-mounted top Picatinny rail systems, these low-profile night sights can serve as back-up sights in self-defense situations, or for close-range target acquisition during competition.

Packaged for right-handed shooters, these sights are ambidextrous, as left-handed shooters simply flip the rear sight and base during installation. The Sight kit comes complete with blue locking thread compound to apply to the rear sight once windage is determined; elevation is adjustable by pressing the detent and rotating the front sight. MSRP on Big Dot and Standard Dot sets featuring a Tritium front and white stripe rear is $150, and $180 for sets with both Tritium front and rear.
