ERA-TAC picatinny rail - Krieghoff Semprio Details

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

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.

This Picatinny mount is attached to the rifle's dovetail (there are no screws included).

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

The product has a warranty period of 10 years.

BH height

BH stands for Bauhöhe (ger.) which means overall height. It is measured from the mounting surface of the rifle to the lower surface of the riflescope's tube.

BH height

6 mm
Inclination

Often, the elevation adjustment that the riflescope offers is not adequate to compensate for the bullet drop when shooting at long range. When the riflescope runs of out of elevation, a mount with an inclination is needed. 20 MOA is the most common inclination. With it, the user gains 58.2 cm / 100 m of additional elevation range when shooting at the range of 100 m. This is approx. 5.8 Mrad of elevation.
