Daniel Defense was founded by an engineer whose voracious will to succeed helped him overcome challenges and fill a void in the market for a more functional and easier-to-use AR platform. After picking up his very first AR in 1999, Daniel realized he needed a flattop upper receiver, which lead him to design and manufacture the very first 100 Black Hole Uppers which enhanced the way sighting systems are mounted. In 2005, Daniel Defense was awarded the US SOCOM contract for their proprietary rail interface system design, known as the RIS II. Passionate about quality control and preventing low production levels, DD has spent over 15 years setting the benchmark for achievement in a competitive market. This commitment has led to the development of incredible gun parts, including handguards and forends, buttstocks, grips, and more that have been closely examined down to every detail with clearly marked settings and consistent coloring.
