Springfield Armory Ronin 45 ACP Optics Ready AOS 5" Barrel PX9120LAOS

The Ronin® AOS in .45 ACP combines a legacy of service with modern features. Built for strength, the Ronin features forged steel slides and frames—carbon steel in the slide and stainless steel in the frame—and a hammer-forged barrel for lasting durability. It includes a standard 5" barrel with a traditional recoil spring assembly and barrel bushing. Enhanced with AOS, the Ronin employs a series of plates fitting popular optics like RMR, Shield, Delta Point Pro, and Docter. Each AOS plate integrates a rear sight, ensuring proper optic height, an intuitive sight picture, and visible co-witnessing in nearly all optic configurations, making the Ronin a versatile, modernized firearm ready for a lifetime of service.
