Whats New At Rosco…

Hello from Rosco,

We wanted to reach out to you folks and tell you about some exciting stuff that has been going on inside our home. The crew has been busy designing a new website ( which is easier to use, navigates well, and is packed with details on “Who we are”, and our newest products. We have also been busy building a new line of HARD USE barrels that are sure to meet and exceed your expectations.


Rosco “Bloodline” series…

Rosco Manufacturing’s “Bloodline” series is our hardest working barrel. Whether you are an occasional builder, tactical shooter, or Law Enforcement Officer we have a barrel that will fit your needs. All of our Bloodline barrels are made from scratch in our Rhode Island facility and start life as a blank piece of steel. All Bloodline barrels are made out of 4150 CMV steel and then completely treated (including the barrel extension) in Salt Bath Nitride to lock out corrosion and enhance performance. 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 most austere of conditions. We are setting out to re-define the rules and we plan on letting our work do the talking…

Coming soon…

Rosco “Purebred” series (precision AR-15/ AR-10 barrels)

We are also steadily working on our “Purebred” precision rifle barrels. The Purebred barrels will be made out of (actual) 416 R stainless steel with a polished NiB extension. The front of the barrel will feature a beautifully cut “Compound/ Step Crown”, and the barrel will use our proprietary “Polishing & Rifling” method. This method ensures that the bore has a smooth finish in order to eliminate break in periods, or accuracy issues due to jagged edges on the lands/ grooves. These barrels will undergo our most stringent manufacturing and quality control process in order to produce a “turn key” precision solution. We hope to have these available by Q4 2017. Please stay tuned to our social media channels on Instagram, Facebook, and You Tube for more details on this product launch and more Rosco Manufacturing news.
