Contessa Base Sako 85S 1 Piece Picatinny Rail V2 20Moa

Contessa Picatinny Rail for Sako 85 S, SM (Short, Short Magnum) (20 MOA)

Introduction

Picatinny rail consists of slots with 5.23 mm spaces between one another, which means that it can be used across its entire length. It is simple to mount and interchangeable – if something is made for a Picatinny rail, it will fit regardless of the manufacturer or manufacturing date. It is affordable, resilient and reliable – this is why it so commonly used by professionals and military. Because of all its great qualities, Picatinny rail has been dominating the rail market in the recent years.

Picatinny is a big step forward from the Weaver standard. Weaver has a few predesignated slots while Picatinny has slots all over its surface, allowing the device to be mounted wherever the user finds it fitting. Weaver’s slot is 3.8 mm wide, which is why ring mounts made for a Weaver rail will also fit on a Picatinny rail while ring mounts made specifically for a Picatinny rail will not fit on a Weaver rail. This is one of the main reasons why Picatinny is a far better mounting solution.

Contessa is an Italian company, famous for producing aesthetically appealing mounts with a nice finish. The tolerances of the produced pieces are very tight – there are no deviations, the mounts are very carefully machined. Contessa’s Picatinny rails are made from steel and come with their unique screws which fit nicely into the rail. The screws have a huge contact surface and a bigger head than screws of other mount manufacturers, while the thread is the same. Contessa’s Picatinny rails, made in Italy, are available in both 0 MOA and 20 MOA versions. Throughout the middle of the rail, there is a canal so that the rail can be used together with rifle’s sights.

20 MOA 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, use of rail with 20 MOA is greatly recommended. 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.
