Buy Vortex Optics from BattleHawk Armory! When shooters demand the quick-handling characteristics of a red dot, but suffer starburst effects in red dots from common astigmatism, the Spitfire AR is the perfect choice. The glass-etched DRT (Dual Ring Tactical) reticle can be used with or without the red/green illumination like a traditional riflescope, and makes target and reticle acquisition in close-quarters a snap. Unique to the Spitfire AR, an included 5.56 BDC turret allows shooters to dial popular AR-15 configurations to 700 yards-perfect for limited division 3-Gun competitors or range-goers who wish to engage targets from point blank to extended range. DRT (MOA) RETICLE The DRT (Dual Ring Tactical) reticle is designed for rapid shooting at close distances. The dual ring design pulls the eye into instant alignment with the reticle center and target. Etched directly on the prism to assure consistent point-of-aim at all times with selectable red/green illumination of five intensity levels to match specific conditions. Battery Life: Up to 250 hours on highest setting. Up to 3,000 hours on lowest setting. Prism Scopes are not compatible with the VMX-3T Magnifier.
