The 12.5" length offers a solid balance of velocity and maneuverability, making it well suited for defensive builds, duty use, or a compact range rifle. The 13.5" HWKXL handguard extends past the muzzle for a tucked, suppressor-ready look while maintaining a lightweight 6061-T6 free-float platform with plenty of usable rail space.
