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
