Description
The Rosco Manufacturing Bloodline M4 Contour is a 16-inch replacement barrel chambered in 5.56x45mm NATO for AR-15 platform rifles. It is built for an M4-style carbine setup and is intended for builders replacing or upgrading an existing barrel.
The barrel is made from 4150 CMV steel with a nitride finish and is black in color. It has a 1/2-28 thread pitch for muzzle devices and suppressors and features an 11-degree crown. The barrel is sold as a single component.
Rosco's listing notes that the barrel and barrel extension are nitrided. Buyers should confirm that the barrel fits their receiver and gas system, and that any SBR or suppressor use complies with applicable NFA rules.
