EAW Monoblock Roll-Off Sub Base for Picatinny, ITX Screw

• Roll-off interface for modular setups: This sub base provides the lower half of an EAW Roll-off Mounts system, giving a stable platform for compatible upper components with the EAW Ø 7 mm Interface while keeping the mounting concept flexible.
• Picatinny compatibility: Designed for Picatinny Rail applications, it fits a wide range of rifles and chassis systems, making it a practical choice when moving an optic platform across modern firearms that share the same rail standard.
• Low 10.00 mm build height: The 10.00 mm height helps keep the optic mounting point controlled and compact, which supports a more natural cheek weld and avoids unnecessary bulk above the receiver.
• Aluminium construction: The aluminium body keeps weight down without giving up the rigidity expected from a precision mount component, which is useful on hunting rifles and lighter tactical setups alike.
• ITX screw fixation: The ITX screw fastening system is suited to a secure fixed installation, helping the base stay firmly in place under regular field use and repeated handling.

About the EAW Roll-off Mounts Series

EAW Roll-off Mounts sit in the manufacturer’s range as a more economical alternative to its pivot mounts, while still following the same emphasis on precision manufacturing and dependable fit. The series includes one-piece and two-piece designs, giving users a choice between compact integrated solutions and more traditional split configurations depending on the rifle and optic combination.

The concept is built around practical versatility. Roll-off mounts are intended for lighter firearm setups, including air rifles and small-calibre shotguns, but the range also extends to rifles with integrated dovetail arrangements and to modern platforms using Picatinny interfaces. Depending on the model, the series is available for fixed installation or repeatable attachment with lever-operated versions, so the user can choose between a simpler permanent setup and a mount that can be removed and reattached as needed.

A defining characteristic of the series is its modular design philosophy. EAW offers different top and base components within the system, allowing the mount to be tailored to the rifle, the optic and the intended use. That makes the series relevant for hunting optics as well as general sporting rifle applications where a clean fit, controlled height and reliable alignment matter more than unnecessary complexity.

About the EAW Monoblock Roll-Off Sub Base for Picatinny, ITX Screw

The EAW Monoblock Roll-Off Sub Base for Picatinny, ITX Screw is the lower mounting element in EAW’s roll-off system, intended for rifles and chassis platforms that use a Picatinny rail. As a monoblock sub base, it gives the setup a single-piece foundation, which is useful when consistent alignment and straightforward installation are priorities. It is especially relevant for users building a modular optic mount around the EAW Ø 7 mm Interface, because it creates the connection point for compatible upper components within the system.

The 10.00 mm height keeps the base relatively low, helping to avoid an unnecessarily tall optic position. In practice, that supports a more stable head position behind the sighting system and helps preserve the handling balance of the rifle. The 0° offset angle keeps the geometry neutral, which suits general-purpose mounting where no built-in cant or lateral displacement is required.

Its aluminium construction keeps the part light enough for field rifles and modern sporting platforms, while still providing the rigidity expected from a mount base. The black finish gives it a subdued appearance that matches most contemporary rifles and optics. EAW uses an ITX screw fixation on this version, making it a fixed-installation solution for users who prefer a secure, tool-fastened base rather than a quick-detach lever arrangement. For Picatinny-equipped rifles such as the Accuracy International AX308, AXMC, AT308, Beretta BRX1 (Picatinny) and similar platforms, this sub base serves as a compact starting point for a modular roll-off mount configuration.

About EAW

EAW traces its origins to 1919, when Ernst Apel founded the company in Würzburg, Germany. The business later developed into a specialist manufacturer of scope mounting systems, and since 1951 the development and production of riflescope mounts have been its primary focus. EAW produced its first riflescope mounts in 1945, establishing the foundation for the product category it is still known for today.

The company’s expertise centres on pivot mounts, slide-on or roll-off mounts, and claw mounts, covering both traditional hunting rifles and more modern sporting or tactical applications. Production moved from Würzburg to Gerbrunn in 1970, and Ernst Apel GmbH is now headquartered in Eibelstadt, Germany. Alongside its mounting systems, EAW also offers thermal imaging products, but its reputation remains closely tied to German-made optic mounting solutions built around repeatability, mechanical precision and model-specific fit.
