EAW Steel Picatinny rail, Krieghoff Semprio

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

Krieghoff GmbH is a German weapons manufacturer from Ulm. The company was established in 1886. It is currently in the hands of the fourth and fifth generation of the Krieghoff family. They put a lot of effort into custom stock making – they claim that a stock is one of the crucial parts of a rifle. Today, the company is mostly known for its competition rifles, hunting rifles and shotguns.

Krieghoff Semprio has a classic look but is equipped with a revolutionary repeating system – this is an in-line repeating rifle (similar to pump-action). They started manufacturing it in 2011. It has a take down feature, meaning that it can be easily taken apart and discretely transported. It is chambered for the following calibers: .223 Rem., .243 Win., 6,5x55 SE, .270 Win., 7x64, .308 Win., .30-06 Sprg., 8x57 IS and 9,3x62. The rifle is also available in magnum calibers: 7mm Rem. Mag., .300 Win. Mag. And .375 Ruger. It features a magazine with 4 rounds (+1 extra in the barrel). There are dovetail grooves on the action for mounting purposes.

The first Semprio rifles had both bores and a dovetail. Then, Krieghoff changed the receiver construction. Semprio rifles are now supplied only with a dovetail. To mount EAW Picatinny rail (SKU: 83-00191) on a Semprio, the receiver has to be drilled, tapped and fixed by gluing or soldering on – the rail is still positioned on the receiver with set screws, even on newer models.

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
