Notes: This is a popular bolt-action rifle, light and inexpensive, and grooved for a scope mount. Unlike many of these rifles, the A-Bolt .22 uses a premium walnut stock.

Notes: The A-Bolt Hunter, also known as simply the "A-Bolt," began life in 1986 as a modification of the Browning BBR. The A-Bolt is actually manufactured for FN (Browning) by Miroku of Japan, however, with final fitting being done in the US and Belgium. It was manufactured for short and long actions, with a mechanism very similar to that of the BBR. The bolt, however, is fluted, to allow larger locking lugs, a shorter but more powerful ejector for spent and dud cartridges, and a visible cocking indicator which protrudes from the back of of the bolt sleeve when the A-Bolt is cocked. The sliding safety is on the tang. The magazine and trigger mechanism are more akin to that of the BAR, but a scissors-type feed mechanism was added.

Furniture is walnut with a straight comb to the stock and a pistol-grip wrist, and that wrist and the fore-end are checkered. The butt is coated in thick, textured, hard rubber (it is not a pad). Barrels are chrome-lined and 22 inches long, with no sort of muzzle device as standard though a Boss muzzle brake can be attached at the factory upon request). The original A-Bolts have no iron sights, but are drilled and tapped as well as grooved to accept a wide variety of scopes. Magnum-firing A-Bolts have extra strengthening in the receiver, chamber, bolt, and stock to withstand the extra power, and are therefore built heavier. Left-handed versions were also built, but only in .270 Winchester, 7mm Remington Magnum, .30-06 Springfield, and .375 H&H Magnum. It is also interesting to note that a .30-06 Springfield version was built on the magnum action as well as the standard long action.

Several variants of the original A-Bolt series were built, most of which differ only in detail and are identical to the standard A-Bolt Hunter for game purposes. The A-Bolt Camo Stalker had camouflaged furniture over a laminated walnut stock, and chambered only .270 Winchester, .30-06 Springfield, or 7mm Remington Magnum. The Stainless Stalker used a gray composite stock (a graphite shell filled with fiberglass), metalwork of stainless steel finished in matte gray, and limited chamberings. The Composite Stalker is essentially a Stainless Stalker with more chamberings available and a somewhat darker-colored stock (with a slightly different composite shell) and finish. (Both are lighter than a standard A-Bolt.) The Gold Medallion also has limited chamberings (.270 Winchester, .30-06 Springfield, and 7mm Remington Magnum), a palm-swell wrist, a Monte Carlo comb, and various decorative spacers and scrollwork in gold and bronze. The Medallion is essentially a deluxe version of the standard A-Bolt, similar to the Gold Medallion but having a high-gloss finish to boot, and available in all A-Bolt chamberings (however the .375 H&H Magnum version was discontinued in 1991, while the .300 Winchester Magnum chambering was discontinued in 1995). The Micro-Medallion is a short version of the Medallion, with a 20-inch barrel, smaller magazine, shorter length of pull, and chambered only for short-action rounds. The Micro-Medallion cannot be fitted with the BOSS muzzle brake.

All original A-Bolts were replaced in production by the new A-Bolt II series (see below).

Notes: The Browning A-Bolt II is for the most part identical to the original A-Bolt, but has a few internal changes; the action is much less likely to stick or bind, even in cold or inclement weather, due to a non-rotating sleeve on the bolt, an improved trigger action, and a better extractor. In addition, barrel lengths vary greatly with caliber and the model of the rifle involved. Most of the same types of A-Bolts are available in the A-Bolt II series, with the exception of certain calibers on certain types, and for the most part they are identical to the original A-Bolt series for game purposes. There are also a number of newer versions of the A-Bolt as part of the A-Bolt II series.

It should be noted that while most versions of the A-Bolt II series are actually built for FN/Browning by Miroku in Japan, or at least have the parts manufactured there, final fitting and touches are done by FN/Browning in Belgium or their facilities in the US.

The base version of the A-Bolt II is the Hunter, as with the original A-Bolt. A-Bolt II Hunters have barrels ranging from 21-16 inches depending upon the chambering; these barrels are free-floating and have target crowns. Metalwork is largely low-luster blued, and the walnut furniture has a satin finish with a recoil pad on the butt and checkering on the pistol grip wrist and fore-end. The Hunter FLD is designed specifically for the new short magnum and super short magnum cartridges. The barrels of this Hunter variant are 22 inches for the super short magnums, or 23 inches for the short magnums. Like the rest of the A-Bolt II series, they are free-floating; like most of the series, they are target-crowned and glass-bedded. The trigger is adjustable. The stock is of low-luster walnut, with a recoil pad on the butt and a raised cheekpiece. The pistol grip wrist and fore-end are checkered. It should be noted that only Browning dealers rated as "Full-Line" or "Medallion" are allowed to sell the Hunter FLD. For game purposes, the Hunter FLD is identical to the standard Hunter. A new version of the Hunter, the A-Bolt Digital Green, has a composite stock finished in a camouflage pattern; chamberings are restricted to .243 Winchester, .270 Winchester, .270 Winchester Short Magnum, 7mm Remington Magnum, 7.62mm NATO, .300 Winchester Short Magnum, .30-06 Springfield, and .300 Winchester Magnum.

The A-Bolt Medallion is one of the "core" versions of the A-Bolt II series; it is a fancy version of the standard A-Bolt II Hunter. The Medallion has all-steel metalwork (largely finished in blue, and engraved to various degrees according to the wishes of the buyer). Barrels range from 22-26 inches according to chambering, and the barrels are glass-bedded, free-floating, and tipped with a target crown. The receivers are hand-finished. The furniture is of select-quality walnut with a gloss finish, and rosewood end caps on the fore-end and pistol grip wrist. The butt has a Pachmayr Decelerator recoil pad.

The Stainless Stalker is another one of the "core" versions of the A-Bolt II series; it is essentially built the same as the A-Bolt’s Stainless Stalker, but the barrel is glass-bedded, free-floating, and tipped with a target crown at the muzzle. It is built in long and short-action versions, and barrels range from 22-26 inches. The butt has a recoil pad. The Composite Stalker is virtually identical, but is finished almost entirely in matte black, and is available in a smaller range of chamberings (the Composite Stalker is not available in 5.56mm NATO, .223 Winchester Super Short Magnum, .22-250 Remington, .243 Winchester Super Short Magnum, .243 Winchester, .25 Winchester Super Short Magnum, 7mm-08 Remington, or 7.62mm NATO).

The A-Bolt Mountain Ti is a light version of the A-Bolt II, with much of the metalwork made from titanium alloy (though the bolt face, barrel, and some other parts are of stainless steel). Barrels are 22 inches in length for standard calibers and 23 inches for Magnums, and tapered (though with a slender profile), with a target crown. The action is hand-finished. The stock is a Bell & Carlson composite synthetic stock in camouflage finish, and the butt has a Pachmayr Decelerator recoil pad. Some say The Mountain Ti is too light for some of the powerful cartridges it fires. A version with stainless steel metalwork is also available.

The M-1000 Eclipse, often simply called the Eclipse, is designed primarily for more powerful cartridges, and is heavily built from matte-finished blued steel and with heavy hardwood furniture given a laminated gray wood-grain finish. The wrist is of the thumbhole type, and the butt has a recoil pad. The grip and fore-end are checkered. Barrels are all 26 inches and heavy, with a target crown. The action is hand-finished. The Eclipse is a rifle designed for high accuracy at long ranges. The M-1000 Stainless Eclipse is similar, but the metalwork is matte-finished stainless steel.

The Varmint Stalker is designed to fire smaller-caliber, short-action cartridges. External metalwork is matte blued steel, while the furniture is of matte black composite. The butt has a recoil pad. Barrels are 24 inches, except in .22-250 Remington caliber, which has a 26-inch barrel. Barrels are glass-bedded, free-floating, target-crowned, and of a medium-heavy weight. The action is hand-finished. The furniture is still of matte black composite, but the pistol grip wrist and fore-end are checkered.

The White Gold Medallion uses largely stainless steel metalwork with some gold decorative touches. Barrels range from 22-26 inches depending upon caliber and are glass-bedded and free floating, as well as being target-crowned. The action is hand-finished. The stock is gloss-finished walnut, with a raised cheekpiece, checkered pistol grip wrist and fore-end, and a recoil pad on the stock.

Like the older version, there is essentially an A-Bolt II Micro-Medallion; however, it has been re-named the Micro Hunter. The Micro-Hunter is a lighter, short-action-only version of the standard A-Bolt II Hunter. Unlike the older version, however, the Micro-Hunter can be found chambered for some pretty powerful cartridges, including some of the new Winchester Short Magnum rounds. Barrels are still 20 inches, except for the 22-inch barrels of the .22 Hornet and the Magnum versions. The barrels are blued with a matte finish, but are free-floating with target crowns. The other metalwork is likewise matte-finished steel. The furniture is satin-finished walnut, with a recoil pad on the butt; the stock also has a shorter length of pull.

Twilight 2000 Notes: The A-Bolt II series largely does not exist in the Twilight 2000 timeline, with the exception of the Hunter and Medallion, which are very rare. However, due to the fact that most of the parts for the A-Bolt II were manufactured in Japan, the A-Bolt II was issued to or bought in small numbers by Japanese civilians and Home Defense forces. Later, many years after the Twilight War, the A-Bolt II Hunter and Medallion became common export rifles for the Japanese, and by 2025, could be found in many places in the Asian Pacific Rim.
