One Plate, Many Pistols: The Universal Power of the AOS Optics Cut

In the world of pistol optics, mounting standards can be a confusing mess. Different red dots have different "footprints," and historically, you needed a slide milled for one specific optic. The Agency Optic System (AOS) cut changes all of that, and if you own a pistol with this innovative cut, you have access to a new level of modularity—especially with an EGW mounting plate.

We originally designed our plates for the wildly popular Springfield Prodigy, but we quickly realized the secret wasn't the pistol, but the cut. The AOS system is a universal standard, meaning our plates designed for it will fit any pistol from any manufacturer that uses the AOS cut.

What Makes the Agency Optic System (AOS) a Game-Changer?

The Agency Optic System (AOS), developed by the brilliant minds at Agency Arms, is a standardized, modular mounting platform. Instead of milling a slide for a single optic's footprint (like an RMR), the AOS is a unique, robust dovetail cut. This universal red dot mount accepts interchangeable plates, each designed for a specific family of red dot sights.

The universal AOS dovetail cut allows for a variety of optic plates.

The genius of this system lies in its optic plate compatibility. Any plate built to the AOS specification will fit perfectly into any slide with an AOS cut. This gives shooters incredible flexibility to switch optics without needing a new slide. It’s becoming a popular choice for high-end 1911s, 2011s, and even custom Glocks because it allows the optic to sit incredibly low on the slide, which is ideal for achieving a co-witness with iron sights.

Key Benefits of the AOS System:

• Universal Fit: One cut fits multiple optic-specific plates.
• Low-Profile Mounting: Sits the red dot lower on the slide for a better sight picture.
• Incredible Durability: The dovetail design is stronger than traditional direct-mount screw patterns.
• Future-Proof: Easily adapt to new optics in the future by simply swapping plates.

The EGW Solution: Precision-Engineered for the AOS Standard

Our optic mounting plates were engineered from the ground up to the exact specifications of the Agency Optic System. This is the key to their versatility. Because we built them for the universal AOS standard, they provide a secure, drop-in fit on a growing list of firearms that feature this cut.

While many know the AOS from Springfield Armory's lineup (like the Prodigy, TRP, Emissary, and Ronin models), other custom and production firearms are adopting this superior system. If your pistol has the AOS cut, our plate will fit—period.

Machined in Quakertown, PA, from ultra-strong American 7075 aluminum, our plates provide a rock-solid foundation for your red dot, ensuring it holds zero, shot after shot.
