Something from Sig Sauer's Optics group that airsoft players may want a replica done for airsoft, the Bravo4 Battle Sight... "The BRAVO4 expands your vision with a massive 10º field of view, 43% wider than standard 7º 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% more eye relief and our LensArmor™ abrasion-resistant coatings will withstand the harshest conditions."
