ERA-TAC Reducer Ring for One-Piece Mounts

• Reducer ring insert: Adapts a one-piece mount to a different scope tube diameter, making it possible to use the mount with more than one optic format instead of replacing the entire mount.
• Made for ERATAC one-piece mounts: Built as a dedicated mounting accessory for the ERATAC system, which helps maintain a clean fit and straightforward installation on compatible mounts.
• Lightweight plastic construction: Adds the needed spacing without unnecessary weight, so the mount setup stays practical for field or range use.
• Black finish: Blends visually with the mount and scope body for a discreet, uniform appearance on tactical or sporting rifle setups.
• German-made accessory: Produced in Germany, reflecting the same focus on precise fit and dependable function that defines the wider ERATAC mounting range.

About the ERA-TAC Accesories Series

The ERA-TAC Accesories series extends the ERATAC mounting system with practical add-ons designed to adapt a rifle setup to a specific task. Introduced under the ERATAC name in 2010 for the civilian sector and law enforcement, this product family covers more than just simple spare parts. It includes adapters, attachment solutions and interface components that help users configure optics and weapon accessories around real mounting needs.

Within the range, the emphasis is on modularity and compatibility. Some accessories are built around the UNIVERSAL-Interface, allowing users to attach bases or side-mounted equipment such as lights and lasers, while others solve more focused fitment tasks inside an existing mount. That makes the series relevant to shooters who want to fine-tune height, interface type or accessory placement without changing the core mounting platform. Across the line, the design philosophy is straightforward: compact parts, durable materials and a purpose-built form that supports the repeatable, hard-use character associated with ERATAC mounting accessories.

About the ERA-TAC Reducer Ring for One-Piece Mounts

The ERA-TAC Reducer Ring for One-Piece Mounts is a simple but important mounting accessory for shooters who need to match a one-piece mount to a scope with a different tube diameter. Instead of replacing the complete mount, the reducer ring creates the correct internal fit, which can save both cost and setup time while preserving a preferred mounting position on the rifle.

Because it is made specifically as an ERATAC mount accessory, the ring is intended to work as part of a coherent mounting system rather than as a generic improvised insert. In practice, that matters because a properly matched reducer ring helps the scope sit more securely in the rings and supports consistent alignment during installation. For users building or updating a tactical optics or sporting rifle setup, that means less compromise when pairing an optic to an existing one-piece mount.

The plastic construction keeps the part light and uncomplicated while still serving its purpose as a spacing and fitment component. Its black finish also keeps the accessory visually discreet once installed, so it does not interrupt the clean appearance of the mount and scope combination. As a Germany-made accessory, it fits naturally into the ERATAC approach of producing dedicated mounting components for practical rifle use.

About ERA-TAC

ERATAC is a brand of Recknagel GmbH & Co. KG, based in Bergrheinfeld, Germany. Recknagel was founded in 1867 in Albrechts near Suhl, Thuringia, and built its reputation around sights, mounts and firearm accessories. After relocating to Schweinfurt in 1948, the company later moved to Bergrheinfeld in 2006. ERATAC itself was introduced in 2010 as Recknagel’s line of tactical mounts and accessories for civilian and military markets.

In this segment, the brand is known for riflescope mounts, Picatinny rails, backup sights and related weapon accessories. ERATAC mounts are machined from solid aluminum and finished with Mil-Spec Type III hard anodizing, reflecting a design focus on repeatability and hard use. That background makes the brand especially relevant in the field of mounting systems and tactical optics accessories, where fit, stability and compatibility matter as much as the optic itself.
