ERA-TAC picatinny rail steel - Sauer 202 Magnum

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 all mounts made for Picatinny will also fit on a Weaver rail while those made for Weaver will not fit on a Picatinny rail. This is one of the main reasons why Picatinny is a far better mounting solution.

Recknagel is currently the biggest manufacturer of mounts in Germany. Their Picatinny rails, known for great fit and finish, are mostly made of high-grade aluminium (a few are also made of steel), which is why they are very reliable. Screws are included. Currently, a common trend among rifle manufacturers is making receivers out of aluminum – mounting a Picatinny rail made of aluminum on one of those receivers is thus not problematic. Their products are marketed either under the name Recknagel or Era-Tac.

About the rifle

Sauer & Sohn is a firearms manufacturing company with a long tradition – it was founded in 1751 and is thus the second oldest gun manufacturer in the world. One of their most known firearms is Sauer 38H, an advanced semiautomatic pistol that was produced in great numbers – it featured a cocking/decocking lever. They partnered with Swiss company SIG in 1976 – a new line of semi-automatic pistols was launched, branded SIG Sauer.

Sauer 202 Magnum is made in a wide selection of calibers: .270 Wby. Mag., 7 mm Rem. Mag., .300 Win. Mag., .300 Wby. Mag., 8x68S, .375 H&H Mag., .416 Rem. Mag., .458 Lott. The rifle operates on modular barrel change system which allows the user to switch barrels and thus use different calibers. There are two holes on each of the mounting surfaces. Unlike Sauer 202 Standard, Magnum version is only available with a steel receiver.

Sauer 202 Magnum has a similar action as Sauer 202 Medium (Standard). The radiuses of the mounting surfaces are the same but there is a difference in B distance (see the picture below). This is why two-piece mounts made for Sauer 202 Magnum will fit Sauer 202 Medium (Standard) while one-piece mounts made for Sauer 202 Magnum will not fit Sauer 202 Medium (Standard).

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. Make sure that the Picatinny rail is compatible with the the rifle by inspecting the mounting holes on both. Before mounting the rail permanently, apply a minimal amount of thread-locking fluid 278 or 648 on screws and contact surfaces. 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 2.2 Nm) – do not overtighten.

Warranty
