Browning AB3 300 Win Mag 3-Rd Black Steel Detachable Magazine

The Browning AB3 factory replacement magazine is built specifically for the A-Bolt III bolt-action rifle chambered in 300 Winchester Magnum. This detachable staggered box magazine uses a formed steel body with integrated feed lips for reliable feeding and long-term durability, paired with a polymer base plate and shoulder. Finished in a low-glare black oxide, it holds 3 rounds and drops cleanly into the AB3's bottom-well magazine release, making it an ideal spare or replacement for hunting, long-range, and field use.

Designed and built by Browning as an OEM part, this 3-round magazine is the correct accessory for the AB3 (A-Bolt III) long-action rifle platform. The steel body and polymer base plate keep weight manageable while preserving the precise fit and reliable feed geometry Browning engineered into the original rifle. Whether you're replacing a lost magazine or carrying a spare on a hunt, this factory unit restores the AB3 to its full intended capacity.
