In a move that’s generating strong attention across the firearms community, Mid State Firearms has announced the nationwide availability of the microbest bcg, a bolt carrier group long regarded as one of the most trusted components in professional-grade AR-15 builds.

Often described by gunsmiths as the “heart of the rifle,” the bolt carrier group (BCG) controls the AR-15’s most critical functions: chambering, firing, extracting, and cycling each round. The company notes that the quality of this single component determines the rifle’s overall reliability, accuracy, and lifespan.

Industry experts agree that poor machining or substandard materials can lead to failures to feed or extract, while a properly engineered BCG ensures flawless cycling even under sustained use. It’s this reliability that has made Microbest a preferred name among builders seeking mil-spec precision and consistency.

By bringing these components directly to the civilian market, Mid State Firearms provides hobbyists, competitors, and professional armorers access to the same high-performance technology once reserved for OEM rifle manufacturers.
