Spike's Ejection Port Cover Spider

The Spike's Ejection Port Cover Spider is a precision-engineered AR-15 ejection port door designed to protect the internal components of your rifle during storage, transport, and field operations. This cover maintains zero integrity by closing off the ejection port opening—a critical vulnerability on the modern tactical rifle. Spike's Tactical brings custom engraving options to this functional accessory, allowing operators to personalize their rifle while maintaining professional reliability.

Measuring 2.25 inches in length and weighing just 0.06 pounds, the Spider ejection port cover adds negligible mass while delivering measurable operational benefit. The compact dimensions ensure it does not interfere with ambidextrous safety levers, charging handles, or upper receiver accessory mounting. The engraved design maintains aesthetic appeal without compromising the cover's primary function: dust, debris, and moisture exclusion. When closed, the cover seals the ejection port against environmental contamination—particularly important in humid, sandy, or salt-air environments where corrosion and fouling accelerate wear on firing pin components and bolt carrier surfaces.

This accessory is suited for AR-15 platform rifles across all calibers and configurations. Whether you run a patrol carbine, competition build, or service rifle, the ejection port cover functions as a simple mechanical barrier during rifle storage and transportation. It opens freely during normal operation and requires no tools or modifications to install or remove. Shooters and armorers appreciate ejection port covers on rifles stored for extended periods, pre-position caches, or vehicles where dust and salt spray pose ongoing contamination risk.
