    AR-STONER™ has developed a great reputation as a high quality, high value, manufacturer of AR-15 gun parts. Utilizing many of the original designs inspired by the architect of the AR15/M16, Eugene M. Stoner, AR-STONER™ continues to evolve with the needs of today’s competition and recreational shooters. AR-STONER™ upper receiver assemblies are manufactured in the USA in an ISO 9001:2008 registered facility. AR-STONER™ uses CNC machinery, controlled production techniques and mil-spec finishes, resulting in extremely high quality and unmatched reliability. Every part, from the smallest pin to a complete upper receiver assembly, is meticulously inspected for quality at each step of the production process. This attention to detail ensures that every AR-STONER™ customer can carry their product with the same confidence and pride that was put into it at the factory.
