Magpul Enhanced Ejection Port Cover OD Green Polymer for AR-15, M4, M16

The Magpul Enhanced Ejection Port Cover is a drop-in upgrade for the factory USGI port door on AR-15, M4, and M16 platform rifles. Built from impact-resistant injection-molded polymer with corrosion-resistant components, this OD Green cover installs in seconds and is engineered to deliver improved physical strength and corrosion resistance over the standard part. It will not bend or deform from impacts, making it more rugged than traditional metal port covers.
