Frequently Asked Questions

What is the Springfield Armory AOS system?

The AOS (Auto-Optic System) is Springfield Armory's integrated optic mounting platform on their 1911 pistols. It allows users to directly mount red dot sights using specific adapter plates, eliminating the need for custom slide milling.

How do I prepare my 1911 slide for a red dot without an AOS system?

Traditionally, if your 1911 slide is not pre-cut for an optic, you would need to send it to a gunsmithing service like CH Precision. They would mill the slide to accept an optic mount before you can install a red dot.

What torque should I use for the adapter plate screws on a Springfield 1911 AOS?

When installing the adapter plate onto the slide of a Springfield Armory 1911 AOS, it is recommended to torque the screws to approximately 12 to 15 inch-pounds. This ensures a secure fit without damaging the slide or screws.

How can I ensure the adapter plate screws on my 1911 AOS do not come loose?

To prevent adapter plate screws from loosening, it's advised to degrease the thread holes in the slide before installation and apply a small amount of blue Loctite to the screws. Marking the screws can also help detect any movement.
