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.

Design of the Rail
The EAW Steel Picatinny, Winchester 70 Long, 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 4 mounting holes, all secured with 6-48 threading. 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. This Picatinny rail is firmly attached to the rifle with 4 screws, ensuring a secure and stable mount.

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, Winchester 70 Long can be mounted on the following rifles, which share the same mounting standard:
- Kimber 89 BGR (Round Top)

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.
