Truglo’s Prism Tactical Rifle Sight features an etched reticle for increased clarity with or without illumination and a 6-MOA red dot with larger outer ring when you need illumination. Ideal for rapid target acquisition at short and medium ranges, this sight provides an extremely wide field of view. Brightness levels are controlled via digital push-buttons. This sight saves battery life with an auto-off feature that powers the optic down when not in use. Includes an adjustable diopter eyepiece.
