Purebred 16″ 300 Blackout: This Rosco Purebred 16″ 300 Blackout (300 BLK) Barrel is perfectly suited for precision carbine shooters that plan on running only supersonic ammo, or are building a well-balanced hunting platform.
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…

I bought this barrel for a hunting platform. It was the absolute best choice. The quality is superior. It groups flawlessly. The barrel is the heart of the gun. You won’t be disappointed in this one

Heard Rosco barrels were great, so I got me a Purebred barrel in 300 blk. Got on sale too. Sighted the red dot at 50yds, and got 1/2” groups with range ammo. Overly satisfied with my purchase. Highly recomend this barrel.

Purchased this barrel to replace damaged barrel on hunting platform. Out of the box sub-moa excellence. Shooting suppressed only,110 grn., 125 grn., & 150grn. Supersonic and 190 grn., 200 grn., 208 grn., & 220 grn. Subsonic with no problem. Cycled all with no problems, last round/empty mag bolt locks back every time. I would recommend Roscoe Manufacturing barrels to anyone. I have ordered one of their .223 Wylde barrels for a DMR I use daily, and have high expectations it will be an excellent addition to the team.
