Designed at the request of world renown combat veteran and firearms instructor Larry Vickers, Scalarworks PEAK Fixed Iron Sights have redefined the fixed iron sight concept for AR platform rifles. Scalarworks redesigned every major component of the A2 style iron sight when developing the PEAK iron sight. This resulted in enhanced form and function as well as ensured that PEAK iron sights are far more than just a backup sighting system. 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.
