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 BAR MK3 Rifle Review

Browning BAR is a name used both for an automatic military rifle developed by John Browning at the beginning of the 20th century and for a semiautomatic sporting rifle that is based on the automatic Browning BAR and was introduced as a redesign in 1966.

In 1993, the second generation of the rifle was presented under the name BAR MK2 and was manufactured up until 2016 when the BAR MK3 replaced it. BAR and BAR MK2 have identical mounting surfaces – scope mounts that fit BAR will also fit BAR 2. Moreover, apart from the BAR MK3 DBM variant that features an integrated Picatinny rail, the mounting surface on other BAR MK3 models is the same as that on BAR and BAR MK2 which means that all three generations of Browning BAR are suitable for the same scope mounts.

Compared to the MK2, BAR MK3 uses a lighter aluminum receiver which is visually changed for an updated, more refined look. Furthermore, some minor changes can be noticed in the design of the receiver profile, fore-end, and buttstock. The wood on the fore-end blends in with the receiver housing and the buttstock uses softer, oval lines in comparison to the older models.

BAR MK3 consists of a short-stroke, piston-driven gas autoloading system and a bolt with seven rotating locking lugs that lock into the barrel. It features a detachable magazine with a hinged floorplate that can hold three magnum and four standard rounds. The top of the aluminum alloy receiver is drilled and tapped for scope mounts and comes with the same mounting surface as its predecessors - BAR and BAR MK2. In comparison to the other two models of BAR, the BAR MK3 has an upgraded Super Feather Trigger with a pull weight of approximately 1100 g (2.4 lbs.).

The safety knob which blocks the trigger from being pulled is positioned at the rear of the trigger guard and the bolt lock is located on the right side of the receiver. It is activated after the last cartridge has been fired and locks the bolt in the rearmost position. In addition, BAR MK3 is equipped with an inflex recoil pad. 

The barrel lengths on Browning BAR MK3 are 508 mm (20-inch), 559 mm (22-inch) and 610 mm (24-inch).
