LBE Unlimited AREPC AR-15 Ejection Port Cover Assembly Black Steel

The LBE Unlimited AREPC is a mil-spec AR-15 ejection port cover assembly designed as a direct replacement for the factory dust cover on standard AR-15 upper receivers. The complete assembly includes the port door, rod with C-clip, and spring, giving builders and gunsmiths every component needed to install or service an upper in one drop-in kit.

Built from steel and finished in a durable black coating, this cover is engineered to mil-spec dimensions for a proper fit on virtually any standard AR-15 upper receiver. The spring-loaded door pivots on the included rod and is retained by the C-clip, restoring the dust-cover function that keeps debris out of the action when the ejection port is exposed.

LBE Unlimited manufactures this assembly in the USA, and it is a popular choice for replacement builds, gunsmith special uppers, and spare-parts kits. Whether you are swapping a lost or damaged cover during a build or just keeping a complete assembly on hand for field service, the AREPC delivers the correct components to finish the job.
