The Troy 45-Degree Offset Sight Set, M4-style front and dioptic rear, in black (Troy part no. SSIG-45S-MDBT-00), has made Troy Industries Folding BattleSights the choice of special operations and tactical users worldwide. This flip-up set folds compactly to the side of the rifle, and an ambidextrous sight base lets it work seamlessly alongside magnified optics mounted in the primary position. Easy to install and deploy, the sights position their apertures at factory height, and a stainless-steel cross-locking system keeps them upright and zeroed even under extreme combat conditions. Note that this sight is designed for same-plane rail systems only and will not work with a railed gas block set higher or lower than the receiver.
