The Agency Optic System (AOS) cut is the most robust optic cut out in today's market. Some of the key features include a variety of optic adapter plates, modular rear sight placement, wider variety of iron sights, and robust attachment system.
The AOS currently offers plates compatible with the following optic footprints: Trijicon RMR, Leupold DeltaPoint Pro, Vortex Viper, Shield Optics RMS, Holosun 509T, and Aimpoint ACRO (the ACRO plate includes compatible iron sights). Each model (with the exception of ACRO) will have 2 configurations to allow the end user to choose the location of their rear sight (Rear Sight Forward of the Optic and Rear Sight Behind the Optic).
With the AOS cut, the optic will sit as low as a slide with a dedicated optic cut. This allows the end user to have a greater selection of iron sights, they will not require sights for a specific modular optic system (with the exception of the ACRO plate, which includes sights).
The adapter plate features a locking tab, center rib and set screws. Not only is the adapter plate more robust, the adapter plates are precisely machined for each optic. All these factors provide a secure mounting system and a system that will retain zero during re-installation.
Adapter plates are machined from ASTM Steel and are coated with DLC.
This plate is made specifically for the Viper optic footprint. It comes with the adapter plate, a set of screws to mount the plate to your AOS milled slide, and a pair of screws to mount the optic to the plate.
AOS Vortex Viper Plate sold as a single plate in either Rear Iron Forward of the Viper or Rear Iron Behind the Viper
