This video provides an 'abbreviated autopsy' of a KAK K-SPEC Bolt Carrier Group (BCG), focusing on two potential issues: the surface finish of the sand cut rails and the design of the dual ejectors. The instructor highlights that rough sand cut rails can aggressively wear the upper receiver's anodizing or coating. Additionally, the dual ejectors on this specific BCG are noted to have a concave surface, which can dig into brass more aggressively, and they do not retract flush, potentially causing friction and brass material buildup. The owner is advised to contact KAK for resolution.
