About the Winchester

In the year 1866, more than 150 years ago, Oliver Winchester left a significant mark on the history of rifle-making when he founded the Winchester Repeating Arms Company with the intention of producing exceptional guns and ammunition. Oliver Winchester, “a man of vision and influence,” as many considered him, fulfilled his intention and built an industrial empire around the lever-action rifle. Sporting a polished brass receiver, the Model 1866 “Yellow Boy” lever-action rifle was the first gun to bear the Winchester name. Fast forward a few years, to 1880, Oliver Winchester died at age 70, but his legacy remained. The Winchester Model 1892 lever-action rifle soon proved itself to be the moviemaker’s favorite, while revolvers chambered in .38-40 Win., .44-40 Win. and .45 Colt were also well received.

Winchester helped pave the way for modern-day rifle manufacturers, and their decades of experience and craftsmanship can also be seen in their high-quality ammunition. They offer a variety of ammo for handguns, rifles, shotguns, and rimfire rifles. Today, the Winchester brand is owned by the Olin Corporation and made up of numerous members who are devoted to the maintenance, collecting, and learning about Winchester rifles and related products, as well as the role these products held in shaping the history of America’s firearms.

Winchester Model SXP Rifle Review

Winchester SXP, Super X Pump, is a pump-action shotgun first introduced in 2010 as a successor to the Winchester Model 1300 shotgun. The SXP’S action system uses four large rotary locking lugs that are located on the bolthead and lock into the receiver. What makes the SXP different from other shotguns is its special “inertia” bolt that provides the initial rearward movement of the slide. So, if the user fires the weapon one-handed without holding the forend it will often eject the fired shell by itself. It comes equipped with crossbolt safety and a drop-out trigger group that can be easily removed for cleaning, inspection, and lubrication. Its receiver is made of aluminum and the magazine has a 4- or 5-round capacity depending on the length of the shells used.

Which Rifles Have Interchangeable Mounts

Two-piece mounts

For two-piece mounts to be interchangeable the mounting surfaces of the rifles must match in every dimension except the B dimension which can vary. This is because the distance between the two pieces of the mount is not fixed. Rifles that have two-piece mounts interchangeable with Winchester SXP are the following:

Winchester Model 1300

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. Rifles that have one-piece mounts interchangeable with Winchester SXP are the following:

Our Recommendations for Mounts

Picatinny rails

This Picatinny rail from EGW is the only one available. It is made of aluminum, same as the rifle’s receiver and comes with a 2-year warranty.

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.
