The story of Bb-Adams Arms began in 2007 when Michael Adams set out to address the shortcomings of traditional direct impingement AR-15 systems. Driven by a passion for innovation and reliability, Adams developed a patented inverted piston operating system that transformed the AR-15 platform, making it cleaner, cooler, and more dependable. The company's early years were marked by rapid growth and industry recognition, as their retrofit kits and complete rifles gained popularity among civilian shooters, law enforcement, and military users. Overcoming challenges such as market competition and evolving customer needs, Adams Arms continually refined its product line, introducing new models and expanding into Glock slide assemblies and AR-15 parts. In 2025, the brand entered a new chapter under the ownership of Alexandria Pro-Fab, ensuring continued commitment to quality and innovation. Today, Bb-Adams Arms stands as a testament to American ingenuity, with a vision to lead the industry in piston-driven firearm technology and deliver superior products to shooters worldwide.
