Magpul Enhanced Ejection Port Cover – AR-15/M4

The Magpul Enhanced Ejection Port Cover replaces the standard AR-15/M4 dust cover with a design engineered to reduce ejection-related malfunctions. The enhanced geometry creates a wider ejection window and smoother brass deflection path, minimizing the chance of spent cases bouncing back into the ejection port during rapid fire. This is a practical upgrade for shooters experiencing occasional ejection issues or those who want improved reliability under sustained use.

Machined from mil-spec aluminum with a hard anodized finish for corrosion resistance and durability. Installation is straightforward for anyone familiar with basic AR-15 assembly—no gunsmithing required. The cover uses standard ejection port cover hardware and fits all mil-spec AR-15 and M4 upper receivers.
