EAW Steel Picatinny rail, Sako TRG 22/42

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.

EAW is a German company, known for producing top-quality mounts. Their Picatinny rails, which are all made from steel, have a nice finish and come with a unique channel in the middle, allowing the user to clearly see the rifle's sights. Screws are included. EAW chooses only the best materials for their products. All of these great features; however, come at quite a steep price.

About the rifle

Sako is a Finnish firearm producer located in Riihimäki. After World War 2 they began manufacturing rifles. Their first invention was the model L42 rifle. With time, Sako expanded their production, making more than 40 different models of firearms with various rifle chamberings. The company was owned by a series of various owners – currently, Beretta Holding owns the company. In 2013, Sako reached a new production record of over 100.000 rifles produced.

Sako, models TRG 22 and 42 are Finnish sniper rifles. These successors of TRG 21 and 42 were first introduced in 1999 and are still in production today. 
Model 22 is chambered in .260 Rem. and .308 Win. while Model 42 is chambered in .300 Win. Mag. and .338 Lapua Mag. Model 22's barrel length is 51 or 66 cm; model 42's barrel length is 69 cm. Barrels are free floating. Latest 42 models have double plungers for more effective cartridge ejection. Both models are extremely effective at very long range shooting and are perfect for competitions. They are equipped with a 16.5 mm dove-tail. For mounting purposes, there are also six mounting holes on the receiver, three at the front and three at the rear. Bolt has three locking lugs and a 60-degree opening angle. The ejection port is located on the right side of the rifle. Cartridges are ejected automatically when pulling the action.

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.

Warranty
