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 yardsperfect for limited division competitors or range-goers who wish to engage targets from point blank to extended range.Battery Life: Up to 250 hours on highest setting.
