LBE Unlimited AR Extractor Kit Features The LBE Unlimited Extractor Kit is built to mil spec dimensions ensuring the extractor and its related components drop into a standard AR-15 bolt carrier group without fitting issues. The kit bundles the extractor spring O-ring buffer insert and roll pin together covering every small part commonly replaced during an extractor rebuild. Because these parts wear from repeated cycling having a complete kit on hand lets an owner restore reliable extraction without searching for individual components. At just 5.7 inches in overall kit length and a fraction of an ounce in weight the kit ships compact and ready to install. LBE Unlimited has built its reputation supplying US made gun parts and accessories focused heavily on the AR-15 platform and this kit reflects that same attention to fit and function. Whether completing a fresh AR-15 build or restoring an existing upper receiver that has developed extraction issues this kit gives builders a reliable path back to proper function. The included O-ring and buffer insert help maintain extractor tension a common point of failure in AR-15 pattern rifles that see heavy use. Builders and maintainers working on AR-15 upper receivers will appreciate having every small part needed for an extractor rebuild in a single kit.
