This model features a short 11.5-inch barrel with the historically accurate 1:12 twist rate and a classic black finish, making it an excellent choice for builders creating authentic Vietnam-era AR-15 replicas. Authentic GAU-5A Styling The GAU-5A was the U.S. Air Force’s compact carbine variant of the M16 family during the Vietnam War. This Brownells BRN upper captures the distinctive short-barreled profile and overall appearance of the original GAU-5A, allowing enthusiasts to build historically accurate retro rifles with period-correct dimensions and aesthetics. 11.5 Inch Barrel with 1:12 Twist This upper is equipped with an 11.5-inch barrel featuring a 1:12 twist rate, which was the standard twist used on many early GAU-5A and XM177 carbines. The slower twist rate provides authentic performance characteristics consistent with the original military-issue firearms of that era, particularly when using lighter bullet weights common during the 1960s and 1970s. Classic Black Finish The upper receiver and barrel are finished in a durable matte black coating that closely matches the appearance of original military carbines. This finish provides good corrosion resistance while maintaining the non-reflective, classic look desired in retro builds.
