XS now offers from-the-factory installed XS Sights in TROY Folding BattleSight flip-up bases. This complete BUIS set is designed for same plane Picatinny rail systems and is an easy do-it-yourself installation; Kit includes red thread locking compound.
TROY BattleSight front base is upgraded with a XS 24/7 Tritium Front Stripe sight allowing for quick front sight acquisition in all lighting conditions. BattleSight rear base is upgraded with XS CSAT Aperture which incorporates a traditional notch-and-post and peep sight in one. This sight was developed by Master Sergeant Paul Howe; the notch provides a 7-yard zero and the shooter obtains a 100-yard zero by dropping the eye down to the peep sight. This design compensates for the two inch offset that occurs when engaging targets at distance. Made in the USA.
