The Troy Rear Tritium Battle Sight - Black SSIG-FBS-RTBT-00 offers reliable, low-light aiming for AR-15 platforms with a folding rear design that stays out of the way when not in use and locks securely into position when deployed. Built by Troy in a durable black hardcoat anodized finish, this tritium-equipped sight delivers fast, intuitive alignment in dawn, dusk, or nighttime conditions, making it an ideal addition for mission-critical or range work where quick target acquisition matters. Designed for Picatinny rails, the folding rear sight provides a sleek profile without sacrificing precision, compatibility, or durability, and its long gun sight construction ensures robust performance under field conditions. The inclusion of Tritium enhances visibility on the notch ladder, improving sight picture without external illumination, while the discreet black color minimizes glare and maintains a professional appearance on the AR-15 platform. This Troy battle sight complements other armorer-approved accessories, enabling shooters to maintain accurate engagements across varying environments while keeping a compact, ready-to-use setup that integrates seamlessly into existing iron sight configurations.
