The History of Browning

Browning Arms Company was founded in 1880 by the American John Moses Browning, one of the most, if not the most prolific and influential firearm inventor of all time, with the help of his brothers, in Ogden, Utah. A large portion of John Browning's rifle designs have been acquired and produced by other big-name companies, like Winchester, Colt, Remington, Fabrique Nationale of Belgium, and Miroku. Among his most famous guns produced were the 1895 Colt Peacemaker machine gun, the Browning automatic rifle, the .45-caliber pistol, a variety of .30- and .50-caliber machine guns used in World War II; and the Browning Automatic-5 shotgun first introduced in 1902 and still produced to this day. Beside firearms, Browning is also a manufacturer of various other products, such as gun knives, shooting accessories, bicycles, and clothing. In 1977 the Belgian firearms manufacturer Fabrique Nationale (FN) purchased the Browning Company. In 1987 the US Repeating Arms Company (Winchester) was purchased from its former owners. The Winchester brand (licensed from Olin Corporation) was acquired at the same time by FN. In 1990, Société Générale sold the FN company to GIAT Industries.

In 1997, the entire FN family of companies (including Browning and the Winchester) was bought from GIAT by the government of a Belgian region named Waloon and was renamed to Groupe Herstal.

Browning X-Bolt LA Rifle Review

Browning X-Bolt is a bolt-action repeating centerfire hunting rifle first introduced in 2007. It is a long action version of the Browning X-bolt series with the B distance of 93.8 mm. Its name stems from the X pattern that is created by the screws that attach a scope mount to the receiver. Browning also calls this mounting surface the X-Lock Mounting System. The early models came equipped with a single-stage trigger assembly, while the newer ones feature a three-lever X-Bolt Feather Trigger which is also fully adjustable, like its predecessor.

The action is push-feed and has three front-locking lugs. X-Bolt features a proprietary detachable rotary magazine. Its barreled action is mated to the stock and its barrel is button rifled. The safety is a tang-mounted two-position catch, while the button to unlock the bolt is located at the top of the bolt handle. Activating this allows the action to be cycled with the safety engaged. Browning X-Bolt is available in five different action lengths:

Super Short
Short (B: 71.74 mm)
Short (B: 74.74 mm)
Long
Magnum

There are two terms found for similar thing: quick release scope mounts and quick detach scope mounts. Term quick release scope mounts is used mostly in Europe and quick detach scope mounts is used mainly in USA, although they mean the same thing. With these terms we describe a scope mount that can be quickly removed from the rifle in the field without using any tools and quickly attached back on the rifle when needed.

Main advantages:

possibility to use multiple scopes on the rifle,
easy transportation of the scope and the rifle separately,
if scope fails, it is possible to immediately detach it and use iron sights.

FIXED vs DETACHABLE scope mounts

Fixed scope mounts are mounted to the rifle with screws and sometimes even with glue. This means that it is impossible to attach or detach the scope mount using bare hands without using tools. It also means that they are not meant for constantly being attached on or detached off the rifle. Once you screw the mount on the rifle, it normally stays there for a longer period of use.

Detachable scope mounts offer possibility to attach or detach them without using any tools. This is extremely handy while transporting the rifle and the scope separately and it also offers multiple solutions of different optics on the same rifle. Detachable scope mounts can be attached or detached from the rifle in a matter of seconds, using bare hands.

DETACHABLE vs REPEATABLE scope mounts

It is important to know and understand expressions “detachable” and “repeatable” while talking about scope mounts. Term detachable scope mounts implies scope mounts that can be quickly attached or detached without using any tools. However, when you detach this kind of mount and attach it back on the rifle, it is recommended to zero the rifle before using it again. Procedure of detaching and again attaching the mount will probably need a sighting in before next shooting, because mount will not be secured on the rifle in the perfectly same position and conditions as it was before detaching it off the rifle.

On the contrary, repeatable scope mounts are most sophisticated mounts. These scope mounts are also detachable, however – they provide removing scope from the rifle and attaching it back again without zeroing the rifle every time. This means that they are made more precisely and that they are offering a possibility of using different optical sights / scope on the same rifle. These mounts are ideal for hunters who can use optical and iron sights interchangeably, depending on the needs in different situations. With the repeatable scope mounts, it is useful to keep them oiled as well as the upper part of the rifle, so that repeatability is more ensured. With a touch of oil, the repeatability might be better, because parts of the mount will always return to their previous locations.

Different types of repeatable scope mounts:

Pivot mounts,
Dentler mounts,
Picatinny repeatable mounts,
12 mm dovetail repeatable mounts (for break barrel rifles, such as Steyr Duett, Blaser B750, Fair Combi, Fair SLX 800, Bettinsoli rifles, etc.),
Original repeatable mounts, made by manufacturers of rifles for their rifles (Blaser mount, Sauer SUM mount, Mauser M03 mount, Steyr Monoblock mount, etc.).

TIP OFF / ROLL OFF vs SLIDE ON mounts

Nowadays, there are a whole lot of different possibilities, made for attaching riflescopes on the rifles. There are also a lot of different expressions, having the same meaning. It is good to know that tip off and roll off mounts are basically the same thing. They represent quick release scope mounts for dovetails and rails which can be rolled or tipped off the rail vertically to the side of the rail. On the contrary, there are also slide on mounts available on the market. They represent quick release scope mounts that can be slided on or off the rail or dovetail from front or rear side of the rail / dovetail. All of these expressions are mainly used for separate rings that can be attached to the rails / dovetails. As far as functioning the rifle, it does not matter which one of these mounts you choose – tip / roll off or slide on mounts. If they are installed correctly, they are all going to work. However, the main difference between them is the principle of attaching them on rails on dovetails.
