About CMMG

CMMG was established in 2002, when John, Jeff, Gretchen, and Stephanie Overstreet made the decision to create a quality AR rifle that can be afforded by everyone. Since that time, things have continued to get better and better. Although the nature of our business continues to evolve, one thing does not—our commitment to meet each and every morning to pray for Gods wisdom in managing the enormous responsibility that comes with this business. By His grace, we have grown every year! CMMG is constantly looking for new ways to improve our products, processes and company at large. Both our customer service and product lineup continue to be second to none, and all of our rifles and firearms parts are made in the United States from the best materials available. CMMG guarantees its products against defects in material or workmanship for the life of the product. CMMG Inc. will repair, replace or substitute any product(s) if a defect in material or workmanship is found.
