The Troy Ind SSIG45SMDBT00 45 Degree Offset BattleSight Set delivers unmatched durability and precision for serious operators, combining M4 front and diopter rear sights in a black hardcoat anodized finish. These folding BattleSights mount on Picatinny rails and feature an ambidextrous sight base that integrates seamlessly with magnified optics, allowing rapid transition between close-quarters and extended-range targets without losing alignment. The 45-degree offset design positions the apertures at factory height, enabling quick, reliable engagement while maintaining a natural cheek weld and stable sight picture. A stainless-steel cross-locking system ensures the sights stay upright and zeroed under extreme combat conditions, providing dependable performance in dynamic environments. Engineered to fold compactly to either side of the rifle, they preserve rail space and reduce snag hazards during movement. Note that the system is designed for same-plane rail configurations and will not work with railed gas blocks that sit higher or lower than the receiver. Ideal for tactical platforms and special operations where fast target acquisition, rugged construction, and compatibility with existing optics are paramount.
