AB Arms AR-15 Small Parts Kit

The American Built Arms Company small parts kit (brand part no. ABAARSP) bundles the small internal components most likely to need replacing during an AR-15 bolt rebuild or general maintenance pass. The kit includes a firing pin retaining pin, ejector, ejector spring, ejector pin, an extractor spring with insert, the extractor axle, three gas rings, and an O-ring, covering the wear parts that keep a bolt cycling reliably. Rather than sourcing each small part individually, builders and armorers can keep this kit on hand for a quick bolt refresh or to finish out a parts-bin build.
