Ramps on the cover panel and end connectors can urge the connectors apart along the slot, achieving a fixed spacing and securement. Cable slots can be defined between components to route cables under the cover panel and above the handguard. The assembly can enable a secure, tool-free attachment of a cover panel over a weapon handguard slot, allowing for cable management and protective coverage without permanent modification. A related method of use is provided.
