Scalarworks PEAK sights are meticulously machined to be the lightest fixed iron sights in existence, without compromising an ounce of strength. Every Peak sight is CNC milled from 7075-T6 billet, which has vastly superior mechanical properties to 6061-T6, and is used where ultimate strength and durability outweigh cost considerations. Peak Sights have precision CNC milled apertures that are flat toward the shooter, so they won't create highlight bias. Peak Sights have a streamlined profile free of protruding levers and knobs that won't rap your knuckles, or get caught on clothing, gear, and surroundings. Every major component is custom designed with meaningful improvements to function, and precision CNC machined to the highest standards of fit & finish. Peak Sights are designed around a modern 15" sight radius. While carbine length rifles have become the norm, most fixed iron sights still use components designed for the M16A2's 20" sight radius. Peak Sights have manually a...
