EAW Steel Picatinny rail, Mauser K98 with 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 K98k (Bulb)

The Mauser K98k (Bulb) is a controlled feed bolt-action rifle introduced in 1935 and used as the primary infantry rifle of the German army during World War II. It features a bolt handle reshaped and bent for faster operation and direct optics mounting on the receiver. The bolt body has three locking lugs, and the steel parts are blued for rust protection. The rifle includes a Mauser flag-type safety lever and a bolt release lever on the left rear side of the receiver. The K98k has an internal five-round magazine loaded via stripper clips, with the receiver featuring a bulb to guide the clips. The barrel length is 600 mm (23.6 inches), and the receivers come without mounting holes, requiring manual drilling by a gunsmith.

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.
