Black River Tactical 14.5″ 5.56 OPTIMUM Hammer-Forged Barrel & Gas Tube

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.

This barrel can be pinned and welded up to a non-NFA length using a muzzle device over 2.070″ long and is a perfect match for a 13″ long hand guard.

Our precision hammer forging process produces an exceptionally straight and smooth bore finish with ideal land and grooves profiles, all of which are key to maintaining accuracy. The forging process also increases hardness and produces beneficial grain flow alignment which improves toughness.

Our industry leading process was developed specifically to address the unique requirements of precision firearm barrels and includes 5 key improvements to ensure highly uniform and accurate results. This includes an electropolishing treatment before chrome lining.

    I’ve had great luck with BRT barrels. This is my third one. My first was the 12.5” exc and it’s been a laser beam. Then the 8” 300BO. This one (14.5”) barely has 200 rounds through it now. And the great part of ordering from Rooftop Defense is it got to me quickly and with some ramen. I wish every 2A retailer were as great to work with as Rooftop Defense.
