Heym SR 30

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 SR 30 Rifle Review

HEYM's firearms are hand-made and well-known for their exquisite quality. In 1998, HEYM introduced SR 30, a rifle known for having one of the best straight-pull bolt designs. Because a straight-pull rifle action is fast, it needs an easy safety mechanism. HEYM has brilliantly achieved this by a three-position bolt system: half-cock position (100°), where both the bolt and its ball-bearing are locked in place; the 85° position where the safety is released (the firing pin and trigger mechanism are set); and the final position which happens after firing when the user pulls the bolt handle back (ball bearings are retracted, the cartridge is ejected from the action).

The bolt is straight, allowing low scope-mounting. The length of the bolt is the same regardless of the caliber. The top of SR 30's action is rounded, with two mounting holes on both mounting surfaces.

Which Rifles Have Interchangeable Mounts

One-piece mounts

The necessary condition for rifles to have one-piece mounts interchangeable, is that the mounting surfaces of these rifles match in every dimension, but no other rifle has the same receiver dimension as the SR 30.

Two-piece mounts

For two-piece mounts to be interchangeable, the mounting surfaces of the rifles must match in every dimension, except the action length (dimension B in the image above), which can vary. The only case of a rifle which has interchangeable mounts with SR 30 is Heym’s older model SR 21.

Our recommendation for mounts

Fixed mounts

MAK is the only company that produces fixed mounts for the SR 30, but these MAKfix rings are well made, so this choice is a no-brainer for someone who wants quality fixed mounts.

Detachable repeatable mounts

If one prefers to have a detachable repeatable mount, the most popular group of these kind of mounts are pivot mounts and the company EAW offers an excellent example of a pivot mount for SR 30.

Picatinny rails

If one wants to buy a Picatinny rail before mounting a scope mount to expand the mounting possibilities, EAW also offers a magnificent Picatinny rail.

Help us build our riflescope mounts database

If you happen to own this or any other rifle, we would appreciate it if you could help us expand our database by sending us some photos of the rifle receiver (the bare mounting surface of the rifle without the mounts installed). For your help, our company offers a fair return in terms of practical rewards.

Introduction

In recent years we can observe that a trend of Picatinny rail has become widespread and global. It is driven by the NATO standardized rails, more commonly known as the Picatinny rail standard. Picatinny rail being the New Jersey Arsenal that developed it in 1995.

These mounting options are revolutionary. The biggest and best advantage being that the Picatinny rail can be used its entire length and not bordered to a few pre-designed slots like for example the Weaver rail standard was before.

The other main advantage is the ease of use and interchangeability. If a product is meant for a Picatinny rail design it will fit all Picatinny-rails, no matter the manufacturer or date of production.

Picatinny/Weaver Rail

Picatinny Rail and Weaver rail profile

Design

The Picatinny rail is almost exclusively crafted from a single piece of metal (in some cases aluminum). In this manner, the axis of the Picatinny rail is perfectly straight and aligned with the axis of the firearm. Therefore the rifle scope which is mounted onto this kind of configuration is certainly aligned with the rifle / gun and the trajectory of the ammunition.

Weaver rail design on the other hand is usually manufactured in two separate pieces, greatly increasing the possibilities for the axis to be crooked, overlapping, and out of line.

It is always harder to align two separate pieces to a third line than it is to align one piece to another. In this way, the lapping of two mounting rings on a single-piece Picatinny rail is no longer required.

The single-piece rail will assure that both rings are perfectly aligned to each other and that no unwished stress is transferred to the riflescope.

Picatinny compare to Weaver Rail

The Picatinny rail itself is an evolutionary step forward from the older Weaver rail. The main difference between Picatinny rail and Weaver rail is the spacing of the slots. Picatinny rail design has them evenly placed exactly 5.23 mm from one slot to the other, 3 mm deep. For this reason, the mounting options are repeatable and the same as other firearms using the Picatinny rail standard.

Interchangeability was a major driving force in the development of the new standard as different NATO armies need to be compatible with each other.

Weaver rail has 3.8mm wide slots and these slots can be placed anywhere on the Weaver rail and in any number that the producer wished.

Advantages of Picatinny design

A big advantage for using the Picatinny rail design is the ever-present recoil stop. Furthermore, the manufacturing of the rail is not very technically demanding and can be done without the use of state-of-the-art machines which greatly reduces the cost of the finished product, making it very affordable.

The Picatinny rail is easy to mount and usually, this type of configuration does not transfer negative stresses and forces from the fired weapon to the rifle scope.

In addition, the Picatinny rail with its very long useable surface works well for mounting longer rifle scopes or to achieve optimum eye relief.

The durability and toughness are other big pluses for this solution.

Manufacturers of Popular Models

A majority of the Picatinny rings are fixed, but a number of best rated European manufacturers (EAW, MAK,..) have, in recent years, put a lot of effort into the development of detachable ring with100% repeatability, with which it becomes easy to remove the scope from the weapon without the use of tools.

No re-zeroing is needed with such mount options, but these models tend to be expensive.

Weaver and Picatinny Rings

Picatinny rail and weaver rail share one more thing. It is possible to use the Weaver ring and the Picatinny ring on the Picatinny-rails, but it is usually impossible to use the Picatinny ring on the Weaver base. The reason being the above-mentioned positioning and spacing of the slots.

Picatinny mounts have a 5mm recoil stop that goes into the rail slot and since
Weaver rail only has 3.8mm wide slots such rings do not fit on Weaver rails.

Due to this reason, the Picatinny-rails are popular and prevailing on the market in recent years and eventually, these options will completely oust the Weaver rail from the market.
