This Rosco 18″ .223 Wylde Barrel was made to enhance the performance of the original MK12 SPR. The medium contour is well suited for cold bore shots on target as well as keeping the weight at a great balance. Gas ports were sized according to the most popular precision bullet weights and suppressor use.
Rosco Manufacturing’s “Purebred” series is 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 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 Rosco’s Purebred barrels are made from scratch in Rosco’s Rhode Island facility and start life as a blank piece of 416R stainless steel.
