Notes: This weapon was first designed by John Browning in 1908, but production did not begin until 1913. It was built in several production batches: 1913-14, 1920-40, 1947-76, and (by the Miroku Firearms Company in Japan) from 1976 until this day. It is a simple autoloading small-caliber rifle with a tubular magazine in the butt instead of under the barrel. The magazine in the butt has an unusual feature: there is a port cut in the butt allowing the magazine to be half-filled without removing the entire magazine. The original model came in versions firing .22 Long Rifle (the most common by far) or .22 Short (a rare variant). Other variants include the very basic Model A, with a small magazine and overall smaller size; the Model B, an improved model A with a checkered pistol grip butt and better-quality woods; the BAC Deluxe, with a grayed steel receiver (Grade III), or a even more elaborate artwork (Grade IV), or gold-inlaid artwork (Grade V), attractive artwork on the receiver, and a version able to fire .22 Magnum rounds.

Notes: This is basically the updated, semiautomatic counterpart to the BBR. These weapons are very popular in North America, South America, and Europe. It is a very elegant design, simple to use and maintain, and can often be found with engraved artwork (often gold-inlaid). Barrels as were 22 inches long for the standard guns, but a 22-inch barrel was later made available. The first BARs were introduced in 1967, initially called the Browning High-Power Auto Rifle. The .280 version was not introduced until 1988. All BARs have some type of iron sights and are also drilled and tapped.

Variants of the basic design include the Battue, introduced in the mid-1980s; this version has a folding leaf sight at the quarter-rib. It is otherwise identical to standard BAR for game purposes. The BAR Big Game Special Edition was a version in .30-06, using a 22-inch barrel that is heavy and target-crowned. The trigger is gold-plated, and the silver-gray receiver has engraved scenes of a mule deer on the left and white-tail deer on the left. Each scene also has a trophy head of the animal inlaid with gold. Only 600 of this model were built between 1987-88. The BAR Deluxe is just as it sounds, a deluxe version of the BAR; the primary difference is the engraving on the receiver and the quality wood used in its stock, and it is otherwise identical to the standard BAR for game purposes. The BAR Magnum is, as the name indicates, a magnum-firing version of the BAR, with a 24-inch barrel. The .300 Winchester Magnum was introduced in 1969; the .338 version disappeared in 1977, but was re-introduced in 1988. The Safari is basically a Magnum with a heavy barrel and stalking-type iron sights. The Lightweight has a light alloy receiver and a short 20.05-inch barrel; it was introduced in 1996. Shortly thereafter (2000) came the Lightweight Magnum, basically the same as the Lightweight but magnum-firing. The Light Battue Prima was introduced in 2001, basically a Battue built to Lightweight standards and firing a different mix of calibers. In 2002, a number of special versions of the BAR appeared, such as the BAR Evolve, with the light alloy receiver but a full 22-inch barrel. The BAR Light Stalker has a light alloy receiver, stalking-type sights, a dark gray plastic stock, 22-inch barrel, and a limited selection of chamberings.

In 1985, the BAR name was dropped (except in the US), and the rifle renamed the Affut.

Twilight 2000 Notes: These weapons can be found in the hands of many a hunter or militia member. However, only the standard BAR, the Big-Game Special, and the Magnum exist in the Twilight 2000 timeline.
