ERA-TAC Picatinny Rail - Sauer 303

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.

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 aluminum (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, frequently referred to as Sauer, is Germany's oldest firearms manufacturer and the second oldest in the world, founded in 1751. Even though they have been around for nearly three hundred years, they remain innovative. 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.

Sauer 303 is a semi-automatic rifle with a unique mounting system called Sauer ISI rail – the buyer has to keep in mind to get mounts made specifically for Sauer 303. ISI rail allows simple detachment and reattachment and is 100 % repeatable. This same unique rail can also be found on some Sauer 202 models. The medium version is chambered for: .308 Win., 7x64, .30-06 Spring., 8x57 IS, 9.3x62, while the magnum version is available in .300 Win. Mag., .338 Win. Mag. (requires the use of muzzle brake). There are six locking lugs on the bolt.

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 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.
