Springfield Prodigy Optic Plate Compatibility Chart

Springfield Prodigy Optic Plate Compatibility Chart

Oct 12th 2026

Choosing an optic plate for the Springfield Prodigy comes down to two things: confirming that your pistol has the correct Agency Optic System (AOS) cut and matching the plate to your exact red dot model.

The Prodigy's AOS system uses interchangeable plates to accommodate different optic mounting footprints. The plate you need for a Holosun 507K-X2, for example, is different from the one listed for a Trijicon RMR or an EOTech EFLX.

This guide brings the main Springfield AOS plate codes together in one place, with compatible optics, screw-fitment notes, and information about StoneIron Defense alternatives. Compatibility details should always be checked against the current manufacturer's documentation before purchase or installation.

SPRINGFIELD PRODIGY OPTIC PLATE COMPATIBILITY CHART

The following chart summarizes the optic models listed for Springfield's AOS plates. Screw notes and sight-visibility information are configuration-specific; a compatible footprint alone does not establish that every installation detail is suitable.

A12B HEX Wasp, Holosun 407K-X2, Holosun 507K-X2, Shield RMSc, Shield SMSc, Shield RMS2, Swampfox Sentinel, Bushnell RXC-200 and RXU-200 Some models may require screw modification Generally listed as visible; verify the exact optic
A13B HEX Dragonfly, Vortex Viper, Burris FastFire 2 and FastFire 4, Crimson Trace CT RAD Pro Requirements differ by optic; CT RAD Pro screws are listed as incompatible Listed as visible
A14B Trijicon RMR, Trijicon SRO, Holosun 407C-X2, 507C-X2 and 508T, Riton X3 Tactix, Swampfox Justice, Bushnell RXM-300 Several models may require screw modification Bushnell RXM-300 is listed as an exception
A15B Leupold DeltaPoint Pro, EOTech EFLX, Bushnell RXS-250 and RXS-100 Supplied screws are listed as compatible for these models Leupold DeltaPoint Pro is an exception; other listed models are marked visible
A18B Aimpoint ACRO Confirm the exact mounting hardware with the current documentation Listed as visible
A19B Holosun 509T Confirm the exact mounting hardware with the current documentation Listed as visible

Important: This is a summary of documented fitment, not a substitute for the current manufacturer's installation instructions. Check the exact optic model, plate version, and hardware before purchasing.

How to Identify Your Springfield Prodigy Optic Cut

Start with the exact model designation. The Prodigy name alone is not enough to establish compatibility with every mounting plate.

Check the product documentation, original packaging, or Springfield Armory's official product information to confirm that your pistol has the AOS mounting system. Do not assume that every 1911-style pistol or every model in a product family uses the same cut.

The AOS cut is the interface on the slide. The optic footprint is the mounting pattern on the underside of the red dot. The plate connects these two interfaces.

For example, the Holosun 407K-X2 and 507K-X2 use a different mounting interface from the full-size Holosun 407C-X2 and 507C-X2. The similar model names can confuse, but they should not be treated as interchangeable when selecting a plate.

If your pistol's model or optic cut is unclear, confirm it with Springfield Armory before ordering a plate.

Which Springfield AOS Plate Do You Need?

A12B: Holosun K-Series and Shield RMSc Optics

Springfield lists the A12B for the HEX Wasp, Holosun 407K-X2 and 507K-X2, Shield RMSc, Shield SMSc, Shield RMS2, Swampfox Sentinel, and Bushnell RXC-200/RXU-200.

The exact optic model matters, particularly when comparing compact optics with similarly named full-size versions. The A12B should not be selected merely because an optic is manufactured by Holosun or appears similar to another supported model.

Check the screw-fitment note for your specific optic. Springfield's listing identifies some combinations for which the supplied optic screws may require modification.

A13B: HEX Dragonfly, Vortex Viper and Burris FastFire

The A13B is listed for the HEX Dragonfly, Vortex Viper, Burris FastFire 2, Burris FastFire 4, and Crimson Trace CT RAD Pro.

Hardware requirements are not identical across this group. In particular, the CT RAD Pro is listed with incompatible supplied screws, while other models have their own fitment notes.

The Vortex Viper also has a documented limitation: its zero-lock feature may not be accessible when mounted on this plate. That is worth checking before purchasing if access to the adjustment mechanism matters to your setup.

A14B: Trijicon RMR, SRO and Compatible Full-Size Optics

The A14B is listed for the Trijicon RMR and SRO, Holosun 407C-X2, 507C-X2 and 508T, Riton X3 Tactix, Swampfox Justice, and Bushnell RXM-300.

Although these optics share a plate family, their screw requirements and sight visibility can differ. Do not assume that screws supplied with one optic will fit another optic on the same plate.

Springfield's fitment information also identifies the Bushnell RXM-300 as an exception for iron-sight visibility. If backup sight visibility is important to you, verify the exact optic and plate combination rather than relying on the plate code alone.

A15B: Leupold DeltaPoint Pro and EOTech EFLX

The A15B is listed for the Leupold DeltaPoint Pro, EOTech EFLX, and Bushnell RXS-250/RXS-100.

The EOTech EFLX uses the Leupold DeltaPoint Pro mounting footprint, which explains why the two optics are listed under the same Springfield plate family. This does not mean that every optic with a similar appearance or a broadly similar mounting pattern is compatible.

Springfield's fitment listing distinguishes iron-sight visibility between supported optics in this group. Check the specific model before choosing this plate.

A18B: Aimpoint ACRO

Springfield's plate compatibility listings identify the A18B for the Aimpoint ACRO family.

Confirm that your exact ACRO model is covered by the current documentation, and check the relevant hardware requirements before installation. Do not infer screw specifications from another plate or optic.

A19B: Holosun 509T

The A19B is listed for the Holosun 509T. This model should be distinguished from other Holosun optics, including the 407C, 507C, 407K, and 507K families.

Confirm the exact model and mounting hardware against current documentation. Similar branding does not establish a shared mounting interface.

StoneIron Defense Springfield Prodigy Optic Plates

StoneIron Defense offers aftermarket plates for several common optic families used with the Springfield Prodigy. Its product listings describe plates made from stress-relieved 4140 steel with a black nitride finish and integrated rear-sight features.

The following product mappings are based on the StoneIron Defense catalog and should be checked against the current listing before purchase.

StoneIron Defense product Intended optic family Product page
SID-1161 Holosun 407K/507K and other listed compatible compact optics View SID-1161
SID-1159 Trijicon RMR/SRO and other listed compatible optics View SID-1159
SID-1160 EOTech EFLX and other listed compatible optics View SID-1160
SID-1158 Vortex Viper/HEX Dragonfly and other listed compatible optics View SID-1158

These aftermarket plates should be evaluated using the same criteria as factory options: exact optic compatibility, pistol fitment, hardware requirements, sight visibility, and installation instructions.

Do not assume that a third-party plate shares every specification or limitation of the corresponding Springfield plate. Follow the instructions supplied by the manufacturer of the plate you purchase.

Optic Footprints, Screws and Rear-Sight Visibility

Why optic footprints matter

A plate must match both the pistol's mounting interface and the optic's mounting footprint. Two optics from the same manufacturer can require different plates.

Confirm the footprint through the optic manufacturer's documentation, then check the plate manufacturer's compatibility listing. A footprint match alone is not enough if the plate is not designed for your specific pistol.

Plate screws versus optic screws

There are two separate mounting interfaces:

  • Plate-to-slide screws: Secure the AOS plate to the pistol.
  • Optic-to-plate screws: Secure the red dot to the plate.

The correct screw length and installation specification can differ between these interfaces. A screw that is too long may protrude beneath the plate and interfere with proper mounting.

Springfield's installation instructions specify a maximum of 25 in-lb for the factory plate-to-slide screws covered by those instructions. Do not automatically apply that figure to optic-to-plate screws or third-party plates. Follow the applicable manufacturer's instructions for each assembly.

If screw compatibility is uncertain, stop and obtain guidance from the plate or optic manufacturer. Do not force a screw or improvise a mounting specification.

Integrated rear sights and co-witness

An integrated rear sight does not guarantee that the iron sights will be visible through the optic window.

Sight visibility depends on the exact plate and optic combination. Springfield's fitment information identifies exceptions among its supported optics, so check the specific entry if you want to retain a usable iron-sight picture.

Treat manufacturer-listed sight visibility as a configuration-specific specification, not a promise that every optic on the same plate will co-witness.

How to Verify Compatibility Before Buying

Use this checklist before ordering:

  1. Confirm the exact Springfield pistol model and that it has the appropriate AOS cut.
  2. Record the complete optic model number.
  3. Check the optic manufacturer's documentation for the mounting footprint.
  4. Match the optic to the plate manufacturer's compatibility listing.
  5. Verify the plate SKU and the exact supported model.
  6. Review the screw-fitment notes and installation instructions.
  7. Check whether iron sights remain visible if that feature matters to you.
  8. Confirm the current price, included hardware, and return policy with the seller.

If a combination is not listed or documentation conflicts, contact the relevant manufacturer before purchasing. Do not treat an unlisted combination as compatible simply because the optic appears to fit.

Frequently Asked Questions

Does the Springfield Prodigy come with an optic plate?

A: The supplied configuration can vary. Check the product listing and documentation for your exact model to determine whether it includes a cover plate, an installed optic, or a particular mounting plate.

Can I use a Holosun 407K and a Trijicon RMR on the same Prodigy?

A: Both optic families have documented plate options for the AOS system, but they do not use the same mounting interface. You would need the appropriate plate for each optic and would have to change the plate when switching between them.

Are the Holosun 407K and 407C compatible with the same plate?

A: No. They use different mounting interfaces and are listed under different Springfield plate families. Check the exact model and plate code before purchasing.

Which Springfield AOS plate supports the EOTech EFLX?

A: Springfield lists the EOTech EFLX under the A15B plate. Confirm the current fitment listing and hardware requirements for your specific optic.

Which AOS plate supports the Aimpoint ACRO?

A: The Aimpoint ACRO is listed under A18B. Confirm your exact optic model and the current manufacturer documentation before ordering.

Does an integrated rear sight guarantee co-witness?

A: No. An integrated rear sight does not guarantee that the iron sights will be visible through the optic window. Check the documented sight visibility for the specific optic and plate combination.

Can I use the same screw torque for the plate and optic?

A: Not automatically. Plate-to-slide and optic-to-plate fasteners are separate interfaces. Use the applicable manufacturer instructions for each.

Final Compatibility Checklist

Before ordering a Springfield Prodigy optic plate, confirm the pistol's AOS configuration, exact optic model, required plate code, screw compatibility, and sight-visibility requirements.

Use the current manufacturer's compatibility information as the final authority. If a model or mounting detail is not documented, obtain confirmation rather than relying on visual similarity or assumptions.

The correct plate is the one explicitly supported for your pistol and optic combination, with hardware installed according to the applicable manufacturer instructions.
