Raid the field using the BSA 3x30 Prism Sight. This scope is designed to help you gain a tactical advantage in close quarters combat by giving an illuminated reticle with five brightness levels and two built-in iron sights. You can switch between the two aiming methods instantly depending on your situation. The illuminated reticle offers a cross pattern with selectable blue or green illumination and five brightness settings to match most lighting conditions. The optical system highlights are a 30mm objective for light gathering, a 3x magnification for notable close-ups, fully multi-coated lenses for improved brightness and low glare, and a 3.15" eye relief. The aluminum housing is robust and durable and and has a Weaver mount for attaching to your firearms. To correct your trajectories at longer ranges, the scope also has windage and elevation adjustments with 1/3 MOA clicks.
