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 barrels will deliver optimal extended range performance time after time.
This barrel is OPS Inc compatible.
Rosco Manufacturing’s “Purebred” series is a testament to precision and quality manufacturing. They 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 their 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 theirselves to the most stringent quality standards. This is the only way that they can make sure that they are producing a product that will perform time after time under the demanding of situations. They are setting out to re-define the rules and they plan on letting their work do the talking…
