Redefining Manufacturing

When we say made in America with pride, we mean it. We are rebelling against the standard practices and setting out to continuously evolve in order to always bring you a better product. The idea of buying products from multiple vendors and slapping them together in order to package it and sell it to you is not our idea of conducting business. Our mantra of “We either do it right, or not at all” is what guides us and gives us bearing throughout the entire process. This is a promise to you, our consumer. We will always strive and work hard in order to earn your business.


Our prototype development is handled in-house, supporting flexibility throughout the entire engineering process. We encourage collaborative engineering, believing that only your team members can help our experts produce exactly what you need. At Rosco Manufacturing we carry many stock items ranging from various AR 15 models assemblies & barrels to accessories. Anything we do not currently produce will of course be taken into consideration to support your firearm industry needs.


From initial concept to order placement, our customer service representatives will be there for you to answer any questions and to make sure your timeline requirements are seamlessly executed. We have high volume capabilities and your customers will appreciate the standards of excellence we hold our products to. Accuracy is paramount and it runs through everything that we do here at Rosco Manufacturing.

Letter from the Owner

Hello, My name is Mike D’Angelo Jr. I was lucky to be born in this great country, fortunate to have been taught about hard work at an early age, and blessed every day to be able to build what I love for you to enjoy. I know that there are a ton of options available in today’s market. This is why I whole heartedly thank you for your business and hope to earn your trust. Trust is a big thing for me. It is my belief that all great relationships are built off of this one simple concept. All too often companies will promise you one thing and deliver another. No level of “slick” marketing or fancy packaging can replace quality. This leads to a broken bond with the consumer and that is something that I am not alright with. Now, I can sit here and tell you that we will be the best in the world overnight, but that is not what I want. All I ask for is your attention, and in time our actions will speak louder than any words uttered before. Let’s MAKE BARRELS GREAT AGAIN!
