The Seekins Precision Enhanced Bolt Catch is an easy to install upgrade that improves the functionality of any MIL SPEC lower receiver. Designed to make bolt manipulation easier, the unique, oversized bolt catch has an aggressive, diamond texture for positive operation. The bottom portion of the catch is also larger and diamond textured, greatly assisting the operation of locking the bolt back. Manufactured using metal injected molded (MIM) process allowing the selection of a proprietary material that is considerably stronger than our original billet model or a factory MIL SPEC Bolt catch. ArmorBlak coating.
