STEYR A1 / A2 · MRA
OuterImpact MRA for Steyr A1 and A2 – precise model list instead of a general "fits Steyr"
The plate uses the rear sight mount and is designed for specific Steyr A1/A2 pistols. If you carefully match the model and optic footprint, you get a reversible red dot base without slide milling.


Black-Raptor quick check: Confirmed for S-A1, C-A1, M-A1, L-A1, M9-A1 as well as L9-A2, M9-A2, and C9-A2. 7075-T6, approx. 3.3 × 51.3 × 26.9 mm, 1 oz. No universal adapter for every Steyr pistol.

Compatible Steyr models
OuterImpact lists the models S-A1, C-A1, M-A1, L-A1, M9-A1, L9-A2, M9-A2, and C9-A2. This makes the selection pleasantly clear: not just the brand, but the exact A1/A2 version decides.


Mounting principle
Model-specific dovetail/rear sight adapter instead of an additional Picatinny intermediate layer.


Material
7075-T6 aluminum with black anodizing.


Dimensions
Approx. 3.3 mm high, 51.3 mm long, and 26.9 mm wide.


Weight
1 oz / about 28 g according to the manufacturer.


Which optics belong to the MRA family?
The MRA covers many classic mini red dot formats – including RMR/SRO, Docter, DeltaPoint/Pro, several Vortex models, FastFire, and C-MORE. K-footprints like Holosun 407K/507K belong to the Micro family. This keeps the buying decision clear: first the firearm model, then the optic footprint.


Buy if … your Steyr is exactly on the confirmed A1/A2 list and your red dot belongs to the MRA compatibility group.


Don’t buy if … you own a different Steyr model or the optic uses a K/Micro footprint for which OuterImpact provides a Micro adapter.



Practical tip: The dovetail mount requires precise alignment. Watch the manufacturer’s installation video and torque specifications before installation; do not tighten screws with arbitrary values from another mount system.
External user experiences
Verified buyers on the manufacturer’s site report, among other things, a successful M9-A2-MF combination. Another user highlights the clear instructions and specified torques; another explicitly recommends watching the installation video before mounting. These are individual experiences but support the importance of proper mounting preparation.
