Introducing the Troy Industries GAU-5/A/A, a semi-auto rifle that is as much a piece of history as it is a tool of precision. Crafted to commemorate the 45th anniversary of the Son Tay raid, this rifle is a faithful reproduction of the original GAU-5/A/A carbine used by the U.S. Air Force. Collectors and enthusiasts alike will appreciate its historical significance and the attention to detail that has gone into its construction. This GAU-5/A/A is in very good condition, with only light, superficial signs of handling or use.
It features a bright and clean bore with excellent rifling, and it's compliant with modern regulations.
The rifle comes with a classic CAR-15 style stock, an A2 pistol grip, and a ribbed handguard, offering a nostalgic yet functional design. It includes a 10-round magazine and an OD web sling, making it ready for display or action. The barrel, measuring 16 inches, is highlighted by a pinned flash hider, adding to its authenticity and appeal.
The GAU-5/A/A is a remarkable blend of history and functionality. As a tribute to the original, this model maintains the simplicity and effectiveness of its predecessor. The original GAU was designed for compactness and mobility, weighing just 5.2 pounds and measuring 28.3 inches with the stock collapsed—ideal for operations requiring quick deployment and ease of handling. Unlike the Army’s XM177E2, the GAU-5/A/A does not feature a forward assist or shell deflector, which remains true to its original design.
This rifle is not only a collector's dream but also a practical firearm for modern use, with its AR-15 direct impingement action and a capacity of 10+1 rounds. Whether you’re a history aficionado or a firearms enthusiast, the GAU-5/A/A offers both a tangible connection to the past and a reliable performance for today.
