Description
The Rosco Manufacturing Bloodline Mid-Length is a 16-inch replacement barrel for AR-15 rifles, chambered in 5.56x45mm NATO. It is built from 4150 CMV steel with a black nitride finish and a 1:7 twist rate, making it suited to a range of standard 5.56 loads.
The barrel uses a 1/2-28 thread pitch for muzzle devices and suppressors, and it carries an 11-degree crown. The barrel and barrel extension are nitride finished. The listing describes it as suitable for builds that run suppressed or sit within an NFA framework, and all NFA rules apply to it.
