Adcor Defense, Inc. is a wholly owned subsidiary of Baltimore, Md.- based Adcor Industries, Inc. For over 20 years, Adcor Industries has served as a national defense contract supplier. In that capacity, it built nine of the very critical components for the Trident missile system, radar system components for the F16 fighter, and other components for the U.S. military small arms industrial base. With its diverse manufacturing capabilities and expertise as a defense industry supplier, Adcor was in an ideal position to design and build its own unique version of the M4 automatic rifle: Adcor Defense, Inc. was formed for that purpose. The product of years of hands-on experience and experimentation by inventor, Michael J. Brown, the Adcor Defense B.E.A.R. (Brown Enhanced Automatic Rifle) is not a new and improved AR: It has a patented (Patent #065111.00128) revolutionary gas piston system and other key features that set it apart from all other M4-type rifles.
