The New Ar-15 Complete Owner's Guide is a completely new volume that complements Walt's The AR-15 Complete Assembly Guide. Walt's ongoing research into the design and history of the AR brings light to new information and questions. Even the most experience and knowledgeable AR aficionado is likely to find something that only now is coming to light. Walt is a Benefactor Life member of the NRA, an emeritus Board member of The Garand Collectors Association, a Life member of the Ohio Gun Collectors Association, and a charter and Life Member of the Ruger Collectors' Association.
