Leaner, meaner, and featuring a redesigned HD optical system for a significantly smaller, lighter tactical solution, the new Vortex Spitfire HD Gen II 3x and 5x models let you choose your ideal mounting height while cutting inches and ounces off the original platform. Now with night vision compatibility, the Vortex Spitfire HD is your dream come true, running on a BDC-style reticle designed to subtend with most popular 5.56 cartridges for quick holdovers at known distances to keep you locked on target. Plus, the prism design and etched reticle give you ultra-fast target while still functioning without illumination. Battery: CR 2032 Click Value: 1 MOA Eye Relief: 2 Mfg: Vortex Optics
