This 8.2” Rosco barrel was designed for SBR/ Pistol use in conjunction with suppressors. This is the shortest that we will go to allow you the flexibility of a shorter Personal Defense Weapon (PDW) without sacrificing performance or ballistic performance. ALL NFA RULES APPLY!
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 Rosco’s Purebred barrels are made from scratch in our Rhode Island facility and start life as a blank piece of 416R stainless steel.
Aside from making their own barrel blanks, and barrel extensions, Rosco also holds themselves to the most stringent quality standards. This is the only way that Rosco can make sure that they are producing a product that will perform time after time under the demanding of situations.
