Rosco Manufacturing Purebred 14.5" 6mm ARC SPR 1:7.5 Twist Intermediate Stainless Barrel - PB-145-SPR-6MM-7.5-I
Out of stock
This Rosco 14.5″ 6mm ARC Barrel was made to enhance the performance of the 6mm ARC. The SPR 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. This barrel features an Intermediate Gas System, requiring an Intermediate Gas Tube.
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 our 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 our own barrel blanks, and barrel extensions, we also hold ourselves to the most stringent quality standards. This is the only way that we can make sure that we are producing a product that will perform time after time under the demanding of situations. We are setting out to re-define the rules and we plan on letting our work do the talking…
