The Bravo4 expands your vision with a massive 10 degree field of view, 43 percent wider than standard 7 degree sights. That's 53 feet of view at 100 yards vs. 37 feet, which could be the difference between seeing a threat, or not. This prism-powered battle sight also boasts unprecedented edge-to-edge clarity which means your target acquisition will be sure and fast. The patented MegaView aspherical lens eyepiece provides 47 percent more eye relief and LensArmor abrasion-resistant coatings will withstand the harshest conditions. Bravo4 is the world's first Wide Field Battle Sight. Radically new design for professional and civilian MSR/AR-shooters.
