Description
The Rosco Manufacturing Bloodline 14.5-inch barrel is a replacement barrel for AR-15 platform rifles, chambered for 5.56x45mm NATO and marked as compatible with 223 Remington. It is intended for builds in the short-barreled rifle or pistol category, where barrel length and gas system matter most.
The barrel is made from 4150 CMV steel with a black nitride finish on the barrel and barrel extension. It measures 14.5 inches, uses a 1:7 twist rate, and has a 1/2-28 thread pitch for muzzle devices. The muzzle is finished with an 11-degree crown. The retailer states that the twist rate, gas port diameter, and materials were chosen for the barrel length, and that all NFA rules apply to this barrel.
