Musgrave K98

The History of Musgrave

The Musgrave company was founded in 1950 by Benjamin Musgrave who was a respected large-caliber target shooter in the 1930s. In 1933, he started testing and improving the accuracy of his Lee Enfield rifle, drawing the attention of other target shooters in South Africa. This attracted so much demand from South African target shooters from 1933 to 1950 that he eventually needed help managing the workload, so he had to bring in his son Trevor to help.

In 1952, Musgrave's reputation as a target shooter landed him a spot on the South African international team. During a competition in the UK, he met barrel manufacturer W.D. Lain. Lain agreed to train Trevor on his rifling machine, which was moved to South Africa in 1953, marking a new phase of the Musgraves' business. Later, they expanded their operation to include another son, Benny Musgrave Jr.

In 1969, Armscor approached the Musgrave family with an idea to start producing commercial hunting rifles. Musgrave became an Armscor subsidiary in 1971, and the first rifles were introduced a year later. In the following years, the company manufactured over 6000 hunting rifles annually using various designs and components. This included rifles with Santa Barbara Mauser actions as well as their action designs. For some time, Musgrave also produced .22LR rifles called Ambidex.

In the 1990s, after the arms embargo ended and South Africa democratized, the company began to struggle, and production eventually ceased. Their assets were sold off or moved to Vektor, a state-owned company. In 2009, businessman Frikkie du Plooy purchased the Musgrave brand, and master gunsmith Gary Barnes joined in 2011, helping to re-establish the company.

Even today, many Musgrave rifles are built on the VZ-24 variant of the Mauser Model 98 action. The company offers several hunting rifles including the Musgrave Field, Varmint, Hunter etc. In addition to these, they produce semi-automatic models such as the Musgrave AR 10-12, Musgrave AR 14, and Musgrave AR 16, and also offer a range of custom-built rifles using premium materials.

Musgrave K98 Rifle Review

The Musgrave Model K98 is part of a series of sporting rifles built on the surplus Mauser K98 controlled-feed bolt actions. Compared to other models, they were known to be more cost-effective, having more basic materials and paying somewhat less attention to fit and finish. However, due to the vast number of rifles produced, they can still be found throughout South Africa. Additionally, Musgrave still offers some updated 98 models that share the action with Mauser M98 Standard.

The models using 98 actions are offered in various configurations, from standard to magnum and big bore calibers. Typically, they feature an internal magazine covered by a steel floorplate, with a cartridge capacity of four. Some older versions also come equipped with sights, but the majority of newer variants using the 98 actions do not have pre-installed iron sights.

Notably, Musgrave K98 actions lack the bulb common to most K98 Mausers used for stripper clip feeding. Moreover, newer models use an adjustable Timney trigger, which allows users to modify the weight of the pull to their preference. Overall, the actions maintain a design typical of the Mauser K98 series. This includes the use of two locking lugs on the front and the third 'safety' lug, located at the rear of the bolt, a flag-type safety, and a bolt release lever positioned on the rear left end of the receiver.

The receivers are drilled and tapped on the newer models which feature the holes spacings the same as used on the Mauser M98 Standard. Older versions, however, might have non-standard mounting holes, which could result in differing spreads between them.

Please note that while Musgrave K98 models use Mauser-designed actions, the centerspread of the mounting holes on the receiver may vary. The newer models feature the spacings of the holes the same as used on the Mauser M98 Standard. Older versions, however, might have non-standard mounting holes, which could result in differing spreads between them.

We kindly advise you to measure the distances between the holes on your Musgrave model K98 before purchasing scope mounts.

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.
