Merkel K4

About the Merkel

Affected by the industrial revolution, the beginnings of the Merkel Jagd- und Sportwaffen GmbH began in 1898 when three brothers Albert Oskar, Gebhard and Karl Paul Merkel created a company under the name Gebrüder Merkel. They started manufacturing firearms in 1905 as a relatively small firm and remained like that during the war as the total number of employees hardly ever exceeded 350. Mainly focusing on export, the company even lost some of its foreign markets, hence pushing the innovativeness in the forefront of their marketing strategy which is to this day notable in their workshop diaries from the time. As the hunting rifles production suffered during the war, they struggled for many years after it ended. However, in the following years, their aesthetically built hunting rifles were again gradually beginning to be sought after in 28 foreign countries. In 1924, one of the most unique and recognizable models – Merkel 303 was presented.

Two years after registering a trademark and gaining rights to the use of the term 'Bock' (over-and-under), Gebhard Merkel passed away in 1933, missing a chance of witnessing the ‘Grand Prix’ prize being awarded to the company in 1937 which increased the export business significantly. In the following year, the management was handed over to Adolf Schade and Ernst Merkel. Their rifles were mostly sold to the upper class - diplomats, famous hunters and industrialists became fond of the company's meticulousness and consistent quality which further broadened Merkel's reputation.

During the Second World War, the market network, consisting of many foreign countries, shrivelled little by little. The war industry was once again preventing the company to focus on what they had been known to do best, subordinating the production of hunting rifles to military weapons manufacturing. At this point, they started adjusting their production accordingly to the market demand, supplying other companies with what the industry needed the most - from carburettor to carbine and rangefinder parts.

Despite the war physically destroying or dismantling a large portion of German factories, Merkel was able to escape such fate, most likely due to its good reputation. At the end of 1945, they restarted the production of hunting rifles, however, due to the Soviet occupation, Merkel successors lost all rights to the company which now operated under the new state of the German Democratic Republic. The Soviets familiarized the company with the two most powerful and influential men at that time - Dwight D. Eisenhower and Nikita S. Chruschtschow which resulted in the first man in space – Juri Gagarin – to be given a Merkel Drilling. Consequently, the socialist regime exploited the company’s notoriety, focusing again on supplying the richest and most prominent people such as Josip Broz Tito, Gamal Abdel Nasser and even Mao Tse Tung. Up until 1987, the production of over-and-under rifles reached 150.000 pieces and the company additionally had a breakthrough in the sport shooting market.

After the fall of the Berlin Wall in 1989, they struggled with outdated technology, however, foreign investors helped significantly with the expansion of the company which resulted in the development of some of the new products such as HELIX, SR1, K5 and SxS series. Up to this day, the company preserved the tradition of the high-quality, handcrafted character of their rifles combined with a vibrant history that laid the foundation for one of the greatest firearm companies of the 21st century.

Merkel K4 Rifle Review

First presented in 2005/2006, Merkel K4 is a break-barrel, a single-shot rifle that comes equipped with a hand-cocking system and shares most features with Merkel K3. However, there are some key differences between K3 and K4.

Merkel K4 uses a steel action whereas B3 has an aluminium one which adds a tad more weight to the K4 model. Contrary to K3, K4 also comes with an octagonal barrel option.

The trigger has a three-stage adjustment system that is smooth and responsive. Behind the trigger guard, there is a small rotating lever that can be turned to three separate positions, allowing the user to choose between different trigger weights, ranging from 680 g (1.5lb) to 1587 g (3.5lb).

The hand cocking mechanism is automatically put in ‘off’ mode when the action of the rifle is opened. Positioned behind the hinge, there is a secondary lug that locks the tilting bolt in place for extra safety. Merkel K4 is locked using the unique Suhl tilted block which locks steel-on-steel.

Possible barrel lengths for Merkel K4 are 500 mm (19.6-inch), 510 mm (20-inch), 550 mm (21.6-inch), 600 mm (23.6-inch), and 650 mm (25.5-inch).
