Unity Tactical Fst-Sopa Fast Plate Acro

The Unity Tactical FST-SOPA Fast Plate Acro is a precision adapter designed to mount Acro-footprint mini red dots onto Unity's FAST Offset Optic Base. If you're running a magnified primary optic and want a co-witnessed backup dot, or building a dedicated close-quarters setup, this plate gives you a rock-solid interface that respects both the optic manufacturer's engineering and your mounting requirements.

Built from 7075-T6 aluminum and finished with Type III hardcoat anodize, the SOPA plate handles the wear and vibration of duty use and field shooting. The anodized finish resists corrosion and abuse better than raw aluminum—important if you're bouncing between climates or throwing your rifle in a bag. It accepts any mini red dot that shares the Acro footprint, so you're not locked into one brand; swap optics without changing plates.

Mounting flexibility is where this plate earns its place on modern setups. The plate can position on the FAST Offset Optic Base in three ways: forward cantilever (aggressive co-witness on rifles), centered (neutral standoff), or rearward cantilever (optimal sight picture on SBRs and close-range carbines). That flexibility means one plate works across multiple gun configurations. Installation uses the optic manufacturer's standard hardware, so if you've mounted an Acro dot before, you already know the process.

Compatible with Unity's LPVO Mount equipped with the Offset Optic Base, the SOPA Acro plate is engineered for shooters who demand repeatability and tool-free adjustability. Whether you're outfitting a hunting rifle with auxiliary magnification or setting up a modern carbine for tactical work, this is the interface that bridges optic and base without compromise.

Frequently Asked Questions

Will this plate work with any Acro red dot?

Yes. The SOPA plate accommodates any mini red dot that uses the Acro footprint pattern. You'll use the optic manufacturer's original mounting hardware to secure it to the plate.

What's the difference between the three mounting positions?

The three positions—forward cantilever, centered, and rearward cantilever—let you adjust where the optic sits relative to your magnified optic and your eye box. Forward positioning works for co-witness on full-length rifles; rearward is ideal on shorter barrels where you want the dot closer to your eye. Center is the neutral choice.

Is this compatible with Unity's LPVO scopes?

This plate is designed to work with Unity's LPVO Mount when that mount is equipped with the Offset Optic Base. Check that your mount includes the Offset Optic Base before ordering.

What hardware do I need to mount the red dot?

The plate itself comes with no fasteners. You'll use the hardware that came with your Acro-footprint red dot optic to attach it to the plate—the same fasteners you'd use mounting the dot directly to any other Acro-compatible base.
