The Heym SR-20 is a sporting and hunting rifle designed and produced in Germany. It is considered to be a first-rate rifle with an exhibited European style craftsmanship like you should expect from a higher-end Mauser or something on the order of a Sauer or Styer level of the rifle.
Introduction
Friedrich Wilhelm Heym is a long-established German gunmaker whose principal fame comes from his hand-built sporting guns – rifles, shotguns, drilling – which are virtually tailor-made for his clients. But for those with less wealth, he also makes a stock rifle that can be bought off the shelf – though even this has sufficient variations of barrel length and caliber to be able to suit almost all applicants.
Design
The Heym SR-20 rifle is basically a Mauser action but furnished in three lengths to suit short-medium and magnum cartridge lengths. It is assembled to three possible barrel lengths. It is assembled to three possible barrel lengths; 20.5 in (520 mm), 24 in (610 mm), and 25 in (660 mm); generally the three-barrel lengths parallel the actions, the two shorter lengths being found with either of the two shorter actions and the 26 in with the magnum action, but this is not immutable and Heym will marry whatever barrel and action you wish.

The shortest barrels are usually stocked to the muzzle in Mannlicher carbine style, while the longer ones are partially stocked in the usual sporting rifle manner. Whatever the stock type it will be of high-grade walnut, oil-finished and hand checkered, fitted to the barrel and action in a faultless manner. The sights are usually a front post with a removable hood, and a rear notch fully adjustable for elevation and windage. The receivers are always drilled and tapped for telescope mounts.
The trigger is fully adjustable, and the magazine has a hinged floor-plate released by a catch in the trigger guard. There is a three-position safety catch which gives the shooter a choice of ‘bolt & trigger locked,’ ‘trigger only locked’ and ‘all free’ positions.

User experience
Heym rifles will group to two minutes of arc as they come from the box. They are not inexpensive weapons by any standard of comparison, but the customer gets an accurate weapon, beautifully hand-finished and flawless in operation. The Heym SR-20 is an excellent push-feed rifle with great accuracy.

The only downside that I recall was an odd safety. To fire, the safety must be pushed down, rather than forward. That safety cost me a huge buck in a mountain laurel thicket. These rifles are push feed but are butter smooth.
