Krieghoff Semprio (before 2013)

The History of Krieghoff

Krieghoff began in 1886 as a gunsmith's workshop in the Thuringian town of Suhl, Germany. Founded by Ludwig Krieghoff and his business partner, it was originally named Sempert & Krieghoff. From the beginning, the company's focus was on making hunting rifles but they were soon sidetracked by the advent of World War 1 when the production switched to weapons of war. After the war, the general chaos and hyperinflation caused the arms industry in Suhl to suffer greatly with many arms manufacturers going bankrupt. By winning a huge order from the Netherlands, Krieghoff was able to avoid the same fate and even managed to expand its production by acquiring many machines from one of the bankrupt companies. In 1919 Ludwig Krieghoff sold "Sempert & Krieghoff" to his son Heinrich Krieghoff who had opened his own weapons company a few years prior, and the two companies merged under Heinrich's direction. By the early 1930s, the company employed 150 workers and specialized in making hunting rifles and triple barrel drilling rifles. Because of this, the number of Krieghoff workers sharply increased in the time leading up to the war and especially in wartime, so that in 1944 they employed around 6000 workers. But all this growth soon vanished into thin air when the Russians seized Suhl, dismantled the manufacturing facility and blew it up.

Thus, the Krieghoff family had to start their business from scratch. They fled to Heidenheim near Ulm, a city in what would soon become West Germany, where they opened a new factory. Because of the strict weapons regulations imposed on their nation, they were at first limited to producing only air rifles, but in 1954 they could go back to producing hunting rifles and drillings. However, they did not stop there and soon expanded into the competition shotgun market by employing the original Remington Model 32 core design and building a Krieghoff rifle for clay target shooting, the K-32. This rifle and its successor, K-80, have been a great success for Krieghoff. In 1986, Krieghoff International was founded by Dieter Friedhoff in Pennsylvania, USA, Krieghoff's only location outside of Europe.

Krieghoff Semprio (Before 2013) Rifle Review

Krieghoff introduced the Semprio Repeating Rifle, a mixture of practicality and innovation, in 2007. Semprio is a special, "inline repeating" rifle, operated by pushing the whole front assembly forward to release the seven locking lugs and eject an empty cartridge case. While this repeating system is quite loud, it allows the user to keep his grip and stay on target, which is especially beneficial on driven hunts.

Semprio underwent a reshaping of the mounting surface in 2013. Rifles produced between 2007 and 2013 feature four holes for mounting purposes that are combined with a tip-off mounting surface. The holes were revoked on all the rifles produced from 2013 onward; therefore, the newer versions come with tip-off grooves and two recoil notches.

You can read more about the new version of Semprio in our review by clicking on the link below:

The rifle can be taken apart without the use of any tools and can therefore be easily packed and modified. It is compatible with a variety of barrels and bolts which are easy to mount and interchange with the other components. This makes Semprio a fully modular hunting rifle capable of being converted to other calibers even during the hunt. The rifle features a detachable box magazine – with a 4+1 capacity in standard calibers or 3+1 in magnum calibers – that can be loaded either by pushing the cartridges through the ejection port into the magazine or by reloading the magazine conventionally.

Instead of a traditional safety switch, it features a manual cocking mechanism positioned at the action tang which must be pushed forward to cock the gun and make it able to fire. The cocking lever also functions as a bolt release button. When rotated to the right the whole action can be moved to the rearmost position. In this position, the magazine can be removed easily. Additionally, pushing the knob on the right side of the receiver fully extracts the bolt and separates the front and rear ends of the rifle.

The barrel lengths available for Krieghoff Semprio produced before 2013 are 550 mm (21.7-inch) and 635mm (25-inch).

Scope Mounts Interchangeable With Krieghoff Semprio

Rifles That Have One-Piece Scope Mounts Interchangeable With Krieghoff Semprio

For one-piece scope mounts to fit on a rifle, mounting surfaces on these rifles must match in every dimension.

Rifles That Have Two-Piece Scope Mounts Interchangeable With Krieghoff Semprio

To meet interchangeability conditions, two-piece scope mounts must match in all dimensions except the B distance. B distance can vary because two-piece scope mounts can be installed and adjusted closer or further apart.

Unfortunately, we currently lack information regarding interchangeable scope mounts for the Krieghoff Semprio rifle, manufactured before 2013. Should you have any additional information regarding possible mount matches, please contact us. We would gladly accept your help and expand our database accordingly.

Please be informed that alternatively, the tip-off grooves can be used for mounting purposes instead of holes, making tip-off mounts interchangeable between the two versions of Semprio (manufactured before and after 2013).

Introduction

In recent years we can observe that a trend of Picatinny rail has become widespread and global. It is driven by the NATO standardized rails, more commonly known as the Picatinny rail standard. Picatinny rail being the New Jersey Arsenal that developed it in 1995.

These mounting options are revolutionary. The biggest and best advantage being that the Picatinny rail can be used its entire length and not bordered to a few pre-designed slots like for example the Weaver rail standard was before.

The other main advantage is the ease of use and interchangeability. If a product is meant for a Picatinny rail design it will fit all Picatinny-rails, no matter the manufacturer or date of production.

Picatinny/Weaver Rail

Picatinny Rail and Weaver rail profile

Design

The Picatinny rail is almost exclusively crafted from a single piece of metal (in some cases aluminum). In this manner, the axis of the Picatinny rail is perfectly straight and aligned with the axis of the firearm. Therefore the rifle scope which is mounted onto this kind of configuration is certainly aligned with the rifle / gun and the trajectory of the ammunition.

Weaver rail design on the other hand is usually manufactured in two separate pieces, greatly increasing the possibilities for the axis to be crooked, overlapping, and out of line.

It is always harder to align two separate pieces to a third line than it is to align one piece to another. In this way, the lapping of two mounting rings on a single-piece Picatinny rail is no longer required.

The single-piece rail will assure that both rings are perfectly aligned to each other and that no unwished stress is transferred to the riflescope.

Picatinny compare to Weaver Rail

The Picatinny rail itself is an evolutionary step forward from the older Weaver rail. The main difference between Picatinny rail and Weaver rail is the spacing of the slots. Picatinny rail design has them evenly placed exactly 5.23 mm from one slot to the other, 3 mm deep. For this reason, the mounting options are repeatable and the same as other firearms using the Picatinny rail standard.

Interchangeability was a major driving force in the development of the new standard as different NATO armies need to be compatible with each other.

Weaver rail has 3.8mm wide slots and these slots can be placed anywhere on the Weaver rail and in any number that the producer wished.

Advantages of Picatinny design

A big advantage for using the Picatinny rail design is the ever-present recoil stop. Furthermore, the manufacturing of the rail is not very technically demanding and can be done without the use of state-of-the-art machines which greatly reduces the cost of the finished product, making it very affordable.

The Picatinny rail is easy to mount and usually, this type of configuration does not transfer negative stresses and forces from the fired weapon to the rifle scope.

In addition, the Picatinny rail with its very long useable surface works well for mounting longer rifle scopes or to achieve optimum eye relief.

The durability and toughness are other big pluses for this solution.

Manufacturers of Popular Models

A majority of the Picatinny rings are fixed, but a number of best rated European manufacturers (EAW, MAK,..) have, in recent years, put a lot of effort into the development of detachable ring with100% repeatability, with which it becomes easy to remove the scope from the weapon without the use of tools.

No re-zeroing is needed with such mount options, but these models tend to be expensive.

Weaver and Picatinny Rings

Picatinny rail and weaver rail share one more thing. It is possible to use the Weaver ring and the Picatinny ring on the Picatinny-rails, but it is usually impossible to use the Picatinny ring on the Weaver base. The reason being the above-mentioned positioning and spacing of the slots.

Picatinny mounts have a 5mm recoil stop that goes into the rail slot and since
Weaver rail only has 3.8mm wide slots such rings do not fit on Weaver rails.

Due to this reason, the Picatinny-rails are popular and prevailing on the market in recent years and eventually, these options will completely oust the Weaver rail from the market.
