The A-Bolt Rifle is a bolt-action rifle designed by the American Browning Arms Company. It is manufactured by Miroku Corp in Japan. The A-Bolt replaced the Browning BBR in 1984. It is a popular hunting rifle due to its accuracy and availability.

The A-Bolt rifle is a bolt-action rifle. It uses a non-rotating bolt sleeve (partial sleeve on first generation A-bolt rifles). When the bolt is unlocked, smoothness is achieved with three guide ribs aligned with three locking lugs, enabling precise movement (only on the second and third generation A-bolt rifles). These three locking lugs also greatly increase bolt strength. The bolt's smoothness is also increased with a unique cartridge depressor; the cartridge depressor stays in place independent of the bolt's position. Near the end of the reloading cycle, when the bolt is re-inserted, the bolt moves gently over the cartridges in the magazine. The barrel is free-floating and the recoil lug is glass bedded.

The A-Bolt rifle uses a detachable box magazine. Magazine capacity depends on caliber. Each A-bolt model chambers different calibres, with the Composite Stalker available for 18 calibres in the North America market alone. The available calibre also depends on the country where the rifle is distributed. See the Browning website in the country of choice for the list of available calibres according to the A-Bolt model.

The A-Bolt rifle has many variations, yet most are small differences such as different barrel lengths and caliber.
