The Scalarworks PEAK/01 Fixed Iron Sight solves the common sight radius issue many hunters or competitors experience. These days, many modern traditional iron sights are designed for the M16A2 platform twenty-inch sight radius. However, most modern AR15 enthusiasts use rifles with around a fifteen-inch sight radius leaving the overall sight picture crowded, making target acquisition a real challenge. Scalarworks has redesigned every part of their A2 style iron sights with the PEAK/01, making it far more than a backup iron sight.
