The Magpul Enhanced Ejection Port Cover (brand part no. MAG1206-BLK) is a drop-in upgrade for the standard USGI stamped-steel ejection port cover on AR-15, M4, and M16 platform rifles. Where a factory stamped-steel cover is malleable, prone to corrosion, and needs tools to install, this cover snaps into place without removing your hand guard or barrel nut, and without winding a loose spring or fighting a small e-clip. It’s injection molded from impact-resistant polymer, so it resists bending or deforming from impacts instead of taking a permanent dent. Magpul builds it to fit USGI-pattern AR-15 upper receivers that accept a standard USGI ejection port cover.
