This book provides the prospective, new or experienced AR-15 owner with the in-depth knowledge he or she needs to select, configure, operate, maintain and troubleshoot his or her rifle. The Guide covers history, applications, details of components and subassemblies, operating, cleaning, maintenance, and future of perhaps the most versatile rifle system ever produced.
