The Brownells Retro A1 rifle length barrel is a meticulously crafted component that faithfully replicates the iconic "skinny" barrel design of the original M16A1 rifle. This makes it an exceptional choice for enthusiasts looking to build a retro rifle or any AR-15 configuration where a lightweight barrel is preferred. Chambered in 5.56x45, this barrel features a chrome-lined interior for enhanced durability and corrosion resistance, ensuring reliable performance over time. With a 1-12 inches twist rate, it is optimized for stabilizing lighter projectiles, making it ideal for a variety of shooting applications. The barrel is finished in a matte black phosphate, providing a sleek, non-reflective appearance that complements any build. Measuring 20 inches in overall length, it includes muzzle threads of 1/2-28 tpi, allowing for easy attachment of compatible muzzle devices. Additionally, a standard rifle barrel extension is pre-installed, simplifying the assembly process. Whether you're a collector aiming for historical accuracy or a shooter seeking a lightweight, high-performance barrel, the Brownells Retro A1 is a superior choice.
