Contessa Picatinny Rail for Sabatti Rover 870 (Sabatti Rover LA) (20 MOA)

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 Sabatti

Sabatti has a long-standing tradition in arms manufacturing, dating back to the early 18th century in Val Trompia, Italy, known for metalworking and gunsmithing. The company became prominent with Giuseppe Sabatti in the 1800s as a renowned Damascus steel barrel maker. Post-World War II, Antonio Sabatti and Giuseppe Tanfoglio founded SATA, revitalizing Italian gun manufacturing. They initially focused on hunting shotguns and rifles, introducing pistols in 1956. Sabatti is respected for its barrel and action quality and innovative Multi-Radial Rifling system, enhancing barrel life and performance.

About the Rover 870

The Sabatti Rover 870 is a long action bolt-action rifle with a mechanism loosely based on the Mauser’s Gewehr 98. It boasts a cold-forged chrome-molybdenum steel barrel available in two lengths: 56 cm (22-inch) or 61 cm (24-inch), depending on the specific model's caliber. The rifle has a fixed magazine capacity of up to five cartridges. The Rover 870 features four tapped holes on the receiver for mounting purposes.

Inclination

20 MOA inclination is only needed when the scope runs out of elevation. For example, when shooting at the range of 100 m, shooter gains 58.2 cm / 100 m of additional elevation range with a 20 MOA mount. This is approximately 5.8 Mrad of elevation. To make things even clearer – if the target was placed at 100 m, the scope with 20 MOA inclined rail would aim to the center of the target while the rifle’s barrel would aim 58 cm higher than the scope. This gives the shooter extra elevation needed for long range shooting. If you plan to shoot on distances longer than 600 meters, 20 MOA is most common. There is no negative effect of the inclined Picatinny rail in the mounting setup if you only shoot on shorter distances. The same goes also the other way around, since if you don’t shoot on extreme distances then Picatinny rail with inclination is not needed.

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).
