Also known as: A-Bolt, A-Bolt II, Browning A-Bolt Hunter
Overview
The Browning A-Bolt is a push-feed bolt-action hunting rifle produced by Browning Arms Company from 1985 to 2008, when it was superseded by the X-Bolt. Designed by Browning and manufactured by Miroku Firearms in Kochi, Japan, the A-Bolt replaced the older Browning BBR and pioneered design features that would become Browning hallmarks: a short-throw 60-degree bolt lift, a three-lug rotating bolt that engages a barrel extension rather than the receiver, a non-rotating bolt sleeve to keep the bolt body smooth in the hand, and a free-floating barrel glass-bedded at the recoil lug. The detachable hinged box magazine flipped down for loading without needing to be removed entirely. In 1994 the rifle was updated to the A-Bolt II, which introduced the BOSS (Ballistic Optimizing Shooting System) adjustable muzzle brake and tuner, refined locking lugs, and improved guide ribs for smoother bolt cycling. Available in eighteen calibers including the new Winchester Short Magnum family that Browning helped develop, the A-Bolt earned a strong reputation for accuracy, smoothness, and value, and was offered in walnut Hunter, Medallion and synthetic Composite Stalker trim. An A-Bolt III variant was briefly reintroduced in 2015 with cost-reduced features.

Notes
The A-Bolt II ran from 1994 to 2008, when the platform was replaced by the more rigid X-Bolt with its X-Lock scope mounting system. A short-lived A-Bolt III was reintroduced in 2015 as a value-priced bolt-action positioned below the X-Bolt. Rimfire versions in .22 LR and .22 WMR were produced 1986-1996. The first-generation A-Bolt used a partial bolt sleeve; second and third generations adopted a full non-rotating bolt sleeve with three guide ribs.
Background
When the A-Bolt arrived in 1985 it was one of the first mass-market hunting rifles to put a 60-degree bolt lift, three-lug bolt and detachable box magazine all on the same platform at a working hunter's price. Browning credited Miroku's tooling precision for letting the company offer match-grade machining without match-grade pricing, and the A-Bolt became the rifle that quietly defined what an affordable Japanese-made bolt action could be.
