This Rosco 20″ .223 Wylde Barrel was made to give the precision carbine shooter the best possible option for extended range shooting within this chambering option. Whether you are trying to make a longer version of the MK12 platform or re-barrel your 20” carbine for DCM/ National Matches Rosco’s barrel will deliver optimal extended range performance time after time.
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.
