EAW Steel Picatinny rail, Mauser K98 (Without Bulb)

About Picatinny Rail

The Picatinny rail system is engineered with slots spaced precisely 5.23 mm apart, ensuring consistent and versatile usage along its entire length. This design allows for easy mounting and universal compatibility, meaning accessories designed for a Picatinny rail will fit perfectly, regardless of the manufacturer or production date. Valued for its affordability, durability, and reliability, the Picatinny rail has become a preferred choice among professionals and military personnel, dominating the scope mounts market in recent years.

The Picatinny design represents a significant improvement over the older Weaver standard. While the Weaver system has only a few predetermined slots, the Picatinny rail features continuous slots across its surface, offering greater flexibility for mounting devices at any location. Additionally, the slots on a Weaver rail are narrower, at 3.8 mm, which means scope mounts designed for Weaver rails can fit on a Picatinny rail. However, mounts specifically made for Picatinny rails do not fit on Weaver rails due to the size difference of recoil stoppers. This compatibility and versatility position the Picatinny rail as a superior mounting solution for various applications.

About the Mauser

Mauser, founded in 1811 in Oberndorf, Germany, started as a royal weapon forge and gained fame with the rotating bolt system. This innovation set the stage for the iconic Mauser Gewehr 98, which influenced global military rifle designs. Post-World War II, the factory was dismantled, but Mauser continued to innovate, later merging into what is now known as Mauser-Werke Oberndorf Waffensysteme GmbH. Today, it operates under the Blaser Group, continuing its legacy with models like the M03, M12, and M18.

About the 98 Action (Without Bulb)

The Mauser 98 Action (Without Bulb) is a post-WWII modification of the Gewehr 98, designed primarily for hunting. Unlike the wartime model, which featured a bulb for faster reloading with stripper clips, this version has a larger mounting surface on the receiver, making it incompatible with older scope mounts. The rifle has a bolt with three locking lugs—two at the front and one at the rear—and includes gas vents for safety. It features a two-row internal box magazine with a detachable floorplate, holding up to five rounds. Additionally, it uses a non-rotating claw-controlled feed extractor for reliable extraction. The receiver is equipped with a bolt-release lever and a three-position safety catch located at the rear of the bolt on the action tang. The receivers based on Mauser 98 design feature four holes for mounting purposes, two on the front and two on the rear mounting surface. 

Calibres

The original version of the rifle was primarily chambered for 7.92x57mm Mauser caliber.

Design of the Rail

The EAW Steel Picatinny rail, Mauser K98 (Without Bulb) is crafted from steel, providing exceptional hardness and durability compared to aluminum. This ensures a higher degree of repeatability with minimal wear over time. The rail features 14 slots. A unique central channel allows the simultaneous use of the rifle's iron sights, providing a reliable backup option without needing to remove the rail when there is nothing mounted on it. EAW Picatinny rail for Mauser K98 is without holes – these have to be drilled by a gunsmith.

Usually, a Picatinny rail can be mounted on multiple different rifles if they share the same mounting surface, which we commonly refer to as the mounting standard. The EAW Steel Picatinny rail, Mauser K98 (Without Bulb) can be mounted on the following rifles, which share the same mounting standard:

• Mauser M12 (pre-2019)
• Mauser M98 Standard

Mounting Instructions

Clean the rifle's receiver thoroughly with a cleaning fluid, such as acetone, to remove all stains, grease, and oil. Once the surface is clean and dry, verify that the screws fit both the rail and the receiver holes. Before mounting the rail, apply a minimal amount of thread-locking fluid (278 or 648) to the screws, avoiding any contact with the mounting holes. Carefully clean any excess fluid around the rail using the cleaning fluid. Using a torque driver, tighten the screws to the appropriate torque (up to 3 Nm/26.5 in-lbs). If you require any mounting tools, you can find them on our Rifle Scope Mounting Tools page.
