Overview
The Colt Barrel in 5.56mm NATO features an 11.5-inch length with a Government profile, making it well-suited for compact builds that prioritize maneuverability without sacrificing performance. Its 1:7 twist rate allows for optimal stabilization of heavier bullets, while the carbine-length gas system ensures reliable cycling and reduced recoil.
