Magpul Enhanced Ejection Port Cover – AR-15/M4

The Magpul Enhanced Ejection Port Cover replaces the standard mil-spec dust cover on AR-15 and M4 platforms with a reinforced design engineered to reduce extraction and ejection failures. The enlarged, forward-positioned opening allows spent casings to clear more reliably, particularly beneficial for suppressed rifles, over-gassed systems, or when using steel-cased ammunition. This is a functional upgrade for shooters experiencing brass-to-face issues or short-stroking due to inadequate ejection clearance.

Constructed from impact-resistant polymer with a corrosion-resistant steel pin, the Enhanced Ejection Port Cover installs like a standard dust cover—no gunsmithing required. The ODG (Olive Drab Green) finish matches Magpul's color standard. Installation requires basic familiarity with AR-15 assembly; the cover fits all mil-spec upper receivers.
