Recknagel Picatinny top bases for optic adapters

• Universal interface fit: This top base attaches to the ERA-TAC Universal Interface, turning a modular adapter setup into a platform for compact optics or accessories without changing the underlying mount.
• Picatinny upper surface: The Picatinny rail profile accepts a wide range of red dot sights and compatible tactical accessories, making it easier to configure a rifle for different roles.
• Compact 29.00 mm length: The short base keeps added bulk to a minimum, which helps preserve a tidy, low-profile setup where space and balance matter.
• Aluminium construction: The aluminium body keeps weight down while still providing the rigidity needed for a secure accessory interface on field or range rifles.
• Black anodized finish: The black anodized surface adds wear resistance and reduces visual distraction, helping the base stand up to regular handling and repeated accessory changes.

About the Recknagel Picatinny Top Bases Series

Recknagel Picatinny top bases are part of the brand’s modular mounting ecosystem for shooters who want to build around a proven adapter interface rather than commit to a fixed one-piece solution. Within the Recknagel and ERA-TAC world, these compact top sections are designed to sit on the Universal Interface and provide a practical way to add a Picatinny-compatible upper surface for miniature optics or other accessories.

The idea behind the series is flexibility. Instead of replacing a complete mount, the user can adapt the top side of the system to match a specific application, whether that means fitting a red dot sight for fast target acquisition or adding other Picatinny-based equipment. The series is intentionally compact, helping keep the setup streamlined while preserving the modular character that makes adapter-based mounting useful in the first place. Different BH heights of 11 mm, 19 mm and 27 mm allow the same concept to be tailored to different clearance and alignment needs, which is especially important when combining day optics, clip-on devices and secondary sighting solutions.

About the Recknagel Picatinny top bases for optic adapters

The Recknagel Picatinny top bases for optic adapters are built for shooters who need a simple, secure way to add a Picatinny mounting surface to a modular adapter setup. This version is made to fit the ERA-TAC Universal Interface, so it serves as the connection point between the adapter body and any compatible red dot sight or tactical accessory mounted above it. In practical use, that means the system can be configured around the task at hand without replacing the entire mounting solution.

The base uses an aluminium construction, which keeps the part light and easy to integrate into a rifle setup where unnecessary weight and bulk can affect handling. Its 29.00 mm length keeps the footprint compact, which is useful when mounting smaller optics or when available rail space is limited by surrounding equipment. The black anodized finish adds surface protection against routine wear and gives the part a subdued appearance that matches modern hunting optics and tactical optics setups.

Recknagel offers this design in three BH heights: 11 mm, 19 mm and 27 mm, allowing the top base to be matched to the height requirement of the optic or accessory being installed. That flexibility matters when maintaining proper alignment, clearance and sight picture in a modular system. Torx screws are included, so the base arrives ready for installation with the intended fastening hardware.

About Recknagel

Adolf Recknagel began manufacturing firearm sights in 1867 in Albrechts, near Suhl, Thuringia, giving the company a long connection to German gunmaking. Today, Recknagel is known as a German manufacturer of firearm and riflescope mounting systems, sights and hunting accessories, with a product range that also includes scope mounts, Picatinny rails, triggers, safeties and hunting silencers. The company introduced the ERATAC line of tactical mounts and accessories in 2010, extending its offering toward modern sporting and tactical applications. Recknagel relocated from Schweinfurt to Bergrheinfeld in 2006, and the business entered a new chapter when Dr. Moritz Fehrer acquired Recknagel in 2022. Across its catalogue, the brand is especially associated with precise mechanical solutions for mounting optics securely and repeatably.
