<p>The Vortex&reg; Spitfire&reg; 3x Prism Scope is a great compromise between a traditional scope sight and a reflex sight for shooters who want magnification for precise shot placement at longer ranges, and rapid sight and target acquisition at close range. The Spitfire Prism Scope uses a reticle that&#39;s etched directly to the prism that can be used with or without illumination. Illumination color is selectable from green to red and it has 5 brightness levels. Multiple anti-reflective coatings on all air-to-glass surfaces increase light transmission for positive target ID. The single-piece chassis is O-ring sealed for waterproof and fogproof performance. The Vortex Spitfire 3x Prism Scope comes mounted at a lower 1/3 co-witness height of 40.4mm from the optic center to base surface. If a lower 30mm mounted height is desired the mount riser can be removed.<br /> Manufacturer model #: SPR-1303.</p> <ul> <li>3x magnification</li> <li>Illuminated etched reticle</li> <li>Red/green illumination</li> <li>5 brightness levels</li> <li>Fully multi-coated</li> <li>Co-witness rail mount</li> <li>Waterproof/fogproof</li> </ul>
