The AB3 is more than the sum of its parts. It has proven Browning accuracy, proven Browning design, classic Browning looks, and a level of performance you are accustomed to. The AB3 has the look that endures the test of time, but now the AB3 Pro line gets a well-deserved upgrade. The rifle's spiral fluted barrel reduces weight and offers an aesthetic appeal. The muzzle is threaded 5/8"-24 to accept aftermarket suppressors. The action is bedded and the barrel is free floated for consistent accuracy. Additionally, AB3 Pro rifles are equipped with a teardrop bolt knob, which provides a more secure bolt manipulation by offering a better grip and leverage.
