Heckler & Koch 770

The History of Heckler & Koch

Heckler & Koch was founded in 1948 by Edmund Heckler, Theodor Koch, and Alex Seidel, former Mauser engineers who salvaged materials from the old Mauser arms factory in Oberndorf to start a machine tool plant called the Engineering Office Heckler & Co. The brand was officially registered as Heckler & Koch GmbH in 1949 and initially produced replacement parts and tools for household items and bicycles while also manufacturing firearms.

In 1956, H&K submitted the G3 battle rifle proposal to the German Federal Army, which was based on the Spanish CETME rifle. The G3 was declared the standard rifle of the Bundeswehr in 1959. Over the years, H&K developed various firearms often used by armed forces, such as the HK21 machine gun (1961), MP5 submachine gun (1969), and HK33 assault rifle (1971).

In 1974, the company expanded its product line to include the production of firearms for hunting and sports. H&K was sold to British Aerospace's Royal Ordnance division in 1991, and in the 90s, was awarded contracts to produce updated versions of firearms for Bundeswehr and the US government.

In 2004, H&K won a significant contract for handguns from the US Department of Homeland Security. However, the company has faced allegations of selling small arms to conflict zones and licensing production to governments with poor human rights records, such as Sudan, Thailand, and Myanmar. It has also been suggested that the company found ways to bypass EU export restrictions when its licensed manufacturers sold HK weapons to the areas of conflict.

Throughout the years, Heckler & Koch has presented numerous firearms both for civilian and non-civilian use: from pistols, shotguns, rifles, and machine guns to grenade launchers. Some of the most popular models include the HK A2, HK 416 rifles, the HK P7, P8 and P9 pistols, the HK FP6 shotgun, the civilian use rifles HK 270, HK 630, HK 940, HK SLB 2000, and many others.

In 2019, a Luxembourg-based holding company, Compagnie de Développement de l’Eau (CDE), acquired a controlling stake in Heckler & Koch AG, after being a shareholder for several years. Today, Heckler & Koch's headquarters are still located in Oberndorf in southwest Germany, where they continue to produce a range of firearms for military and law enforcement, as well as weapons for civilian use.

H&K 770 Rifle Review

The H&K 770 is a semi-automatic hunting rifle with a delayed roller-locked bolt system which is engineered to provide a low recoil. It is a hunting version developed from the H&K SL7 model. The barrel and chamber are made of high-quality steel alloy and are hammer forged.

On the top of the receiver, there are square cutouts which can be used for scope mounting. A folding cocking handle on the right side of the receiver allows for easy and fast operation. The rifle has a detachable box magazine, available in 2, 4, or 10-round capacity. The magazine release catch is located in the front end of the trigger guard.

The striker is positioned somewhat unusually on the left side of the action and is surrounded by the wooden body. It comes in the form of a lever, which is rotated to the preferred position by the left hand. For added safety, the rifle can only be put on safe when it is cocked, and the safety lever must fully cover the red dot. Conversely, the safety lever fully covers the white dot when the safety is off.

On the front end of the barrel is a blade sight with a flat top that can be adjusted to change its elevation, while the rear sight is an open square notch that can be adjusted for windage. The production of H&K 770 was stopped in 1991. Models manufactured in the latest years of production come with a ventilated rubber recoil pad.

The H&K models H&K SL6 (.223 Rem.), H&K SL7 (.308 Win.), and the hunting versions H&K 630 (.222 Rem. & .223 Rem.), 770 (.308 Win.), H&K 940 (.30-06 Spr.) share some core features: a delayed roller-locked bolt system, hammer-forged barrels, folding cocking handle, and adjustable sights. The safety lever and magazine release catch are also consistently positioned. However, the SL6 and SL7, with their hybrid sporting and military design, distinctively include wooden handguards and military-style sling swivels. The 630, 770, and 940 are hunting rifles differing mainly in caliber and include options for varying magazine capacities.
