Rosco Purebred 16″ 300 Blackout Barrel
The Rosco Purebred 16” 300 Blackout barrel is perfectly suited for precision carbine shooters that plan on running only supersonic ammo, or are building a well-balanced hunting platform. They took into account the twist-rate, gas port diameter, and barrel length to bring you a high performance, optimally balanced barrel for your next custom AR build.
Rosco Manufacturing’s “Purebred” series is a testament to precision and quality manufacturing. Rosco took a step back to see how they could create a barrel line that would be a culmination of all the lessons learned through years of making barrels for several OEM’s. The result is a barrel that will produce results out of the box for any shooter that is looking to take their skills above and beyond. All of our Purebred barrels are made from scratch in our Rhode Island facility and start life as a blank piece of 416R stainless steel.
