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 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…

The Cobalt Truth

I handled one of these at Firearms Unlimited in Exeter, RI. I have handled and fired a lot of AR’s in my lifetime but the fit and finish on this one is I have to say is the absolute best. I dare you guys or anyone to make a better one.

Thomas Neves
Picked up my first cobalt AR this week. As far as an AR rifle, this I will say is the best elaborate weapons system I have run across as of today…the machine work and design with dual operation components are outstanding. The only thing that would make my rifle any better would be if it was in Tennessee orange and white lol.

Danny Hall
No other AR comes this close to perfection on the market today. Fit, finish, function far surpass anything else, and dual drop means always having the drop in any tactical situation.
