About the Heym

HEYM was founded in 1865, in Suhl, Germany, by Friedrich Wilhelm Heym. Throughout its history, the company has encountered many hardships. These include economic crises, the Nazi regime, and the post-WW II occupation of Germany. Consequently, it has changed its location more than once. Despite that, the Heym brand remains deeply respected and its guns widely admired.

As early as 1891, HEYM manufactured and patented the first hammerless drilling, a three-barreled hunting rifle with three triggers and three hammers on the same axis. Afterwards, the company began to expand, producing drillings, shotguns, and over and under rifle-shotgun combinations. They predominantly exported their products to Russia and the USA. In 1920, the company began producing Anson & Deeley Drillings, double rifle drillings, three trigger drillings, double rifles, and rifle shotgun combination guns.

After World War II, HEYM made a fresh start in the American part of divided Germany. There, the company manufactured products such as cuckoo clocks, slide rules, and spinning wheels since the ownership and making of guns were not allowed. HEYM restored its primary activity in 1952 when the revised laws again allowed the ownership and making of certain hunting and sporting guns.

In 1998, the owner of the company became Thomas Wolkmann. The company's name was first changed to HEYM Waffenfabrik GmbH (Limited), and then in 2007 to the present name, HEYM AG.

Heym 22S Rifle Review

Succeeding Model 22A, Heym 22S is a combination gun first presented in 1973 and manufactured until 1989 when it was replaced by the Model 22S2. Contrary to its predecessor, it features a single set trigger and a recognizable sliding selector positioned on the left side of the breech that allows for quick switching between the barrels.

A tang mounted manual cocking slide is yet another upgrade from the previous models, as it releases the tension on the firing pin when un-cocked and makes the rifle much safer to carry around. Furthermore, a rocker weight system automatically uncocks the rifle if accidentally dropped or bumped, preventing a misfire.

The upper barrel is chambered for shotgun gauges and the lower one for various standard rifle calibres. There are grooves on the sides of the receiver, allowing for an easy instalment of optic mounts. A bead ramp is placed at the front and a folding leaf at the rear of a solid rib barrel.

The possible barrel length for Heym 22S is 610 mm (24-inch).

Despite being primarily produced for Brno ZH rifle, this one-piece mount manufactured by the Croatian company Rusan, is made of steel, comes with a ten-year warranty, and will fit Heym 22S perfectly. Both rifles share the recoil notch which positioned on the same side of the receiver; thus, they also share several mounting solutions.
