Contessa Picatinny Rail for Sako A7 S

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.

About the Sako

Sako, founded in 1921 in Finland, started as a rifle repair workshop and evolved into a premier manufacturer of high-quality hunting rifles and cartridges. Known for innovation, its products became especially popular in the USA post-World War II. The 1980s saw Sako merge with Tikkakoski, adding the Tikka rifle line. Now under Beretta Holding, Sako continues to influence global firearm technology.

About the A7 S

The Sako A7 S (Short action) rifle, introduced in 2008, bridges the price and performance gap between the high-end Sako 85 and the more affordable Tikka T3. This model features a detachable box magazine holding a single-stack column of cartridges. Distinguishing itself from other Sako models, the A7 S uses a receiver with four drilled holes for mounting purposes, instead of the traditional tapered dovetail. Notably, the receiver top lacks the traditional Sako dovetail taper, aligning more closely with Browning A-Bolt and Eurobolt standards in terms of mount compatibility.

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).
