Mossberg Patriot LA

The History of Mossberg

In 1919, Swedish immigrant Oscar Frederick Mossberg, aged 53, launched a journey into firearms manufacture. Alongside his sons Harold and Iver, the trio established what was originally named Mossberg & Sons, Inc., operating out of a rented loft on State Street in New Haven, Connecticut.

The company’s vision was relatively simple: to manufacture durable and reliable firearms for the working class. Their first creation was a modest 4-shot Brownie pistol in .22 caliber, paving the way for a legacy of accessible, dependable firearms.

Just a few years later, in 1922, the Mossbergs produced their first rifle, the Model K. This .22 hammerless pump repeater rifle was in fact initially designed by the famous Arthur Savage but was finalized and improved by the Mossberg team.

As the world descended into war during the 1940s, Mossberg & Sons pivoted its focus to support the war effort. Securing a government license, they began producing tolerance tooling gauges, various machine gun parts, and components of the British Lee-Enfield rifle. During this era, Mossberg also introduced the Model 42MB, a .22 training rifle for British troops. An impressive amount of 45,000 units of Mossberg Model 42MB were produced. This period not only propelled Mossberg onto the global stage but also sparked a period of significant growth for the company.

The post-war years saw Mossberg contributing to the sporadic popularity of bolt-action shotguns, as they produced an array of these firearms. However, today, the company is most renowned for its exceptional pump-action shotguns. Particularly famous is the legendary Mossberg Model 500 pump-action shotgun introduced in 1962. In 1979, the US government awarded Mossberg a contract to produce the Model 500 as a combat-duty-rated pump shotgun. This led to the Model 500 being adopted by every branch of the US Military. By 2010, 41 different variations of the Model 500 were available on the market.

The company’s influence extends beyond firearm manufacturing. Mossberg has introduced several components now commonplace in the industry. For instance, Alan Mossberg developed a safety cable lock in 1989 that now comes as standard with almost every firearm sold today.

Mossberg celebrated 100 years in 2019, and even today continues to be a family-owned and operated business.

Mossberg Patriot (LA) Rifle Review

Mossberg Patriot is a series of bolt-action rifles that first hit the market in 2015. Drawing on Mossberg's 100-year history of firearm production, it showcases the enduring qualities that the company is known for. One of these qualities is the commitment to providing reliable firearms that are budget-friendly.

The Patriot is available in many variants. While each one has unique features, like different sights, barrel lengths, and stocks, they all share the same basic design. This means that no matter which version you choose, you're getting the tried and tested core of the Mossberg Patriot.

One of the things that varies is the barrel length. It could be 413, 508, 559, or 610 mm long (16.25, 20, 22, or 24 inches respectively). Generally, these barrels are fluted, which helps reduce the weight and can help with cooling, and they have a recessed crown to protect the rifle's accuracy.

The barrel's finish is also subject to the specific variant of the Patriot. This could range from Matte Black or Matte Blue to a hardy Cerakote finish.

One of Mossberg Patriot’s strongest points is the so-called “LBA trigger”, which stands for "Lightning Bolt Action Trigger". It shares some similarities with the AccuTrigger you might know from Savage rifles. One of the best things about this LBA trigger is that you can adjust it yourself. You can set the trigger pull weight anywhere between 0.9 to 3.2 kg (2 and 7 lbs) using just a screwdriver.

The trigger has a special safety feature built into it, known as a safety blade. There's a lightning bolt shape cut into this blade - hence the "Lightning Bolt Action" name. This blade needs to be fully depressed before the gun can fire. It's a simple feature that does a big job - it keeps the gun from accidental misfiring.

When it comes to the stock of the Mossberg Patriot, you've got options as well. You can choose between synthetic and wooden stocks, and there's a variety of colors and finishes too - black, brown, natural wood, and even pink.

The stock comes with a nice rubber recoil pad. Depending on the model, you can adjust the length of the pull with spacers that are supplied with specific variants. Some of them even have an adjustable comb height.

Another surprisingly good thing about the Mossberg Patriot considering its low price is the action. It runs smoothly and the bolt seamlessly cycles without any noticeable resistance. Similar to the barrel, the bolt is also fluted, and it has two locking lugs for added safety.

There's also a safety lever just behind the bolt handle. It's got two positions, which makes it simple to operate. Push it forward, and the gun is ready to fire; pull it back, and it's in safe mode. There's also a red dot that shows up when the gun is ready to fire, and it's hidden when the gun is safe. This gives you a quick and easy way to check if the safety is on or not.

The magazine is really easy to load, which is a great feature for those in the field. The release catch is conveniently located right in front of the magazine well, and it detaches without a problem. Most models have a capacity of either 4+1 or 5+1. However, for the larger caliber models, the capacity is a bit less at 3+1. This is fairly standard for rifles of these calibers.

Last but not least are the scope mounting options. All variants are drilled and tapped for scope mounts, but most of them will come with pre-installed Weaver bases or Picatinny rail. If you are looking for scope mounts suitable for any of those options, we invite you to take a look at our offer of Weaver and Picatinny rings:

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.
