Rosco Bloodline Barrel 16" 5.56 1/7

The Rosco Bloodline Barrel 16" 5.56 1/7 is a modern AR-platform barrel purpose-built for tactical and duty applications requiring reliable intermediate-range performance. The 16-inch length strikes a practical balance between velocity retention and handling characteristics, making it a standard choice for patrol rifles, training setups, and general-purpose AR builds where a carbine-length gas system delivers responsive cycling without excessive noise signature.

The 1/7 twist rate is optimized to stabilize a wide range of 5.56 NATO ammunition, from lightweight 55-grain rounds through heavier 77-grain match and barrier-blind loads commonly deployed in intermediate-distance engagements. This twist specification supports both commercial .223 Remington and military 5.56 NATO, offering flexibility in ammunition selection without compromise. The 16-inch dimension maintains the velocity floor needed for consistent barrier performance while keeping overall rifle length manageable in vehicle and confined-space operations.

This barrel configuration appeals to law enforcement operators, military personnel, and serious civilian shooters building or upgrading duty-grade rifles. It performs equally in carbine training courses, patrol-rifle qualification regimens, and defensive shooting scenarios where intermediate-range accuracy and reliability are non-negotiable. The Bloodline line represents a no-compromise approach to barrel manufacturing, suitable for shooters who expect consistent precision and longevity from a core rifle component.
