Rosco Manufacturing® launches new Purebred upper receivers & M-Lok handguards, along with new barrels

April 22nd, 2019: Rosco Manufacturing, an American manufacturer of high-quality gun barrels & accessories, is proud to announce the launching of their newly released products — the Purebred upper receivers, Purebred M-Lok handguards, Purebred 13.7” barrel and Bloodline 12.5” Bloodline barrel. In the never-ending pursuit to expand their list of quality products offered, Rosco has brought their new line of Purebred accessories to the market, including a line of upper receivers and M-Lok rails jointly designed for the barrel maker by industry leading artisans, American Defense Mfg.

The new Rosco designed upper and M-Lok rails feature precision machining from 7075/ 6061 aluminum billet blanks, type 3 hard-coat anodizing and tightened tolerances to enhance the performance/ fitment of the Bloodline & Purebred barrels. Current versions of the rails offered are the 9” & 13.5” M-Lok handguards with the 13.5” and 15” versions having an O.D. Green option ( 15” coming out soon). Rosco is also gearing up to start producing “turn-key” complete Match upper receiver groups which will be custom built for extreme accuracy.

With the launching of the new Purebred accessories series the barrel maker has also launched two new barrels at the immediate request of their customer base. The new barrels are the 13.7” Purebred and 12.5” Bloodline. The 13.7” Purebred is a .223 Wylde chambered 416R stainless steel Mid-length gas barrel that features the same details that has made the Purebred series such a great performing match barrel. The 12.5” Bloodline is a 5.56 chambered 4150 CMV Carbine length gas barrel that is Electro bore polished post Salt Bath Nitriding. The bore polish adds the finishing touches that make the melonite treated Bloodlines such accurate and duty capable barrels.
