BRT OPTIMUM PDW 8.0" HF/CL 300 BLK Barrel 


Black River Tactical Hammer Forged Chrome Lined Barrels are designed and built to meet the needs of serious shooters who demand the highest levels of accuracy and durability along with seamless suppressor compatibility.

Black River Tactical HF CL barrels start with the most durable and accurate blank possible using a precision cold hammer forging process and certified material. The barrels use a medium-light taper profile to keep weight down while maintaining strength. This produces a balanced weapon when a suppressor and other accessories are added. The barrels are finished with an advanced hard chrome lining process that maintains peak accuracy and withstands severe firing schedules.

Black River Tactical HF CL barrels deliver the performance to get the job done in demanding real world conditions.
