Vortex took the successful Spitfire Prism Scope, and redesigned it with a streamlined construction for reduced weight and lower profile. Designed with AR-platforms in mind, the Vortex Spitfire HD Gen II comes equipped with an advanced AR-BDC4 illuminated reticle with a 1 MOA center dot in the middle of an 18.85 open circle for incredibly fast target acquisition. Directly below are four BDC subtensions allowing for accurate shooting at ranges up to 650 yards. The reticle has 12 illumination settings, 2 of which are night vision compatible. The reticle itself has been etched into the glass, allowing for the Spitfire Gen II to continue to function without illumination.
