HK Firearms

Heckler & Koch, commonly referred to as HK, is one of the world’s leading gun manufacturers. Over the years, HK has produced a comprehensive range of firearms, including pistols, machine pistols, assault rifles, machine guns, and training systems.

For over 70 years, HK has been a trusted partner to special forces, law enforcement, and NATO. HK firearms are manufactured with quality, innovation, and precision, setting them apart from other gun manufacturers. With state-of-the-art models and industry-leading technological innovations, HK’s model range is tailored toward a wide range of applications.

History of HK Firearms

In 1949, Heckler & Koch was founded by Alex Seidel, Edmund Heckler, and Theodor Koch. HK was established in an old arms factory in Obendorf, Germany.

To keep up with the German Army’s exponential growth throughout the 1950s, HK signed a contract to manufacture the G3. The HK G3 was inspired by the Spanish CETME. Over time, the CETME design was modified to meet German requirements, resulting in the G3 army rifle.

HK was one of the first manufacturers to use the polygonal barrel profile. Instead of traditional lands and grooves, the barrel uses a polygonal rifling to stabilize the bullet. Many HK advancements have had an impact in the sport and hunting space, from the world-famous polygonal profile to the G3 roller locking system.

In 1997, HK introduced a revolutionary new rifle design—the G36 assault rifle. Unlike the company’s former G3 design, the G36 trades the roller locking system for a state-of-the-art rotation locking system.

Types of Firearms Made by HK

HK’s superior quality and unrivaled legacy can be summed up with the company’s motto: “No Compromises.” HK specializes in developing some of the most sophisticated handguns and rifles in the world.

Some of Heckler and Koch’s highlights include:

  • G3 rifle: Of all the firearms manufactured by HK, the G3 rifle stands out from the rest. The G3, initially manufactured in 1959, is one of the most well-known assault rifles in the world.
  • G36 rifle: The successor of the G3, the G36 rifle, is capable of even greater power and precision than the world-renowned G3.
  • HK45 Compact Tactical .45ACP Pistol: The HK45 was the first firearm manufactured in American plants. Thanks to its exceptional accuracy and precision, it’s one of the most advanced handguns on the market.
  • HK VP40 .40 S&W: The VP 40 was initially introduced in 2014, making it the most recent addition to the HK handgun family. It comes equipped with a striker firing system with a “light pull” trigger that offers superior trigger quality.
