Contessa Picatinny Rail for Weatherby Vanguard LA

About Picatinny Rail

The Picatinny rail system features slots spaced at precise 5.23 mm intervals, enabling consistent and versatile use along its entire length. This system is designed for ease of mounting and is universally compatible; accessories designed for a Picatinny rail will fit seamlessly, irrespective of the manufacturer or the date of production. Known for its affordability, durability, and reliability, the Picatinny rail is a popular choice among professionals and military personnel, making it a dominant player in the scope mounts market in recent years.
The Picatinny design marks a significant advancement over the older Weaver standard. Unlike the Weaver system, which offers only a few predetermined slots, the Picatinny rail boasts continuous slots across its surface. This feature provides the flexibility to mount devices at any preferred location. Additionally, the slots on a Weaver rail are narrower, at 3.8 mm, allowing mounts designed for Weaver rails to 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 make the Picatinny rail a superior mounting solution in various applications.

Mounting Instructions

Remove all the stains (grease, oil etc.) from the rifle's receiver with a cleaning fluid (acetone). Once the surface is clean and dry, check whether the screws match the rail and the holes on the receiver. Before mounting the rail permanently, apply a minimal amount of thread-locking fluid 278 or 648 on screws. Be careful not to get the fluid in or near the mounting holes. Carefully clean the remaining excess fluid around the rail with a cleaning fluid. Using a torque driver, screw the screws appropriately (up to 3 Nm/26.5 in-lbs).
