Magpul Enhanced Ejection Port Cover – AR-15/M16 (FDE)

The Magpul Enhanced Ejection Port Cover addresses a common frustration with standard AR-15 dust covers: premature closure during firing. This upgraded port cover features an integrated spring-tensioned detent arm that holds the cover open during bolt cycling, preventing interference with ejecting cases and eliminating the need to manually hold it open during shooting. It's a simple upgrade that solves a real-world reliability issue.

Machined from mil-spec heavy-duty carbon steel with a durable Flat Dark Earth Cerakote finish, this port cover installs using the standard AR-15/M16 hinge pin—no gunsmithing required. The tool-free installation takes minutes and works with any mil-spec upper receiver. Includes the cover assembly with integrated detent arm and C-clip.
