Description
The Rosco Manufacturing Bloodline Heavy Contour is a 16-inch replacement barrel for AR-15 rifles, chambered in 5.56x45mm NATO. It is built from 4150 CMV steel with a nitride finish and a black color.
The barrel uses a 1:7 twist rate and a 1/2-28 thread pitch for attaching muzzle devices or suppressors. It features an 11-degree barrel crown and a nitride-finished barrel extension.
The raw retailer description states the barrel is suited to builds in the SBR or pistol category, and that all NFA rules apply to those configurations.
