Perfect backup rear sight for low-light conditions

Troy mounts are durable, heavy-duty, and designed to survive the toughest environments. Easily installed, they position the rear sight aperture the exact same height as the factory sights. With no levers or springs to fumble with, deployment of the sight under-stress is easy. The robust stainless-steel cross locking system ensures your sights will remain up and zeroed in the most extreme combat conditions. To fold, simply press the release-button located on the left side of the sight, and push down. All Troy Sights feature a zero-canting attachment system for use on all military and aftermarket receivers.
