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. Rosco 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 the Purebred barrels are made from scratch in their Rhode Island facility and start life as a blank piece of 416R stainless steel.
Aside from making their own barrel blanks, and barrel extensions, they also hold ourselves to the most stringent quality standards. This is the only way Rosco can make sure that they are producing a product that will perform time after time under the demanding of situations.
Please note, we do have a number of available upgrades and services to offer with these barrels, and more information can be found about them under the SERVICES section of our website, listed at the top/header of the page.
