Talley RMR400 RMR Mount Beretta A400 Black Anodized Aluminum

The Talley RMR400 is a precision-machined, low-profile direct-mount optic base engineered specifically for the receiver of Beretta A400 series shotguns. Designed around the Trijicon RMR footprint, this American-made mount accepts Trijicon RMR-pattern micro red dot optics and gives A400 owners a clean, factory-aim-friendly co-witness platform without the need for a separate rail or riser.

The RMR400 is CNC-machined from high-grade 6000 series aluminum alloy and finished in a rugged black anodized coating for corrosion resistance and long service life. It measures 1.78" long and tips the scales at roughly 0.5 oz, so it adds virtually no perceptible weight to the host shotgun. Talley's signature one-piece direct-mount design clamps solidly to the A400 receiver, returning the optic close to the bore for repeatable zero and a compact sight picture.

Rings are not included - this base is intended to be paired with the Trijicon RMR (or any optic sharing the RMR mounting footprint) using the optic's own hardware. Whether you're running a Beretta A400 Sporting, Xtreme, Xcel, or another A400 variant, the Talley RMR400 provides a lightweight, purpose-built mounting solution from a respected American manufacturer.
