Rosco Manufacturingâ€™s Purebred Barrels are a testament to precision and quality manufacturing. We took a step back to see how we could create a barrel line that would be a culmination of all the lessons learned through years of making barrels for several OEMâ€™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. Browse ourÂ Purebred AR barrels today!
