Spike's Ejection Port Cover Bio Hazr

The Spike's Ejection Port Cover Bio Hazr is a custom-engraved AR-15 ejection port door designed to keep debris, dirt, and environmental contaminants out of the upper receiver when the rifle is not in use or during equipment transitions. This accessory is ideal for duty-oriented shooters, military units, law enforcement teams, and serious sport competitors who prioritize weapon longevity and operational readiness.

This precision-machined cover snaps securely over the ejection port opening, offering reliable retention without requiring additional tools or permanent modification. At a verified weight of 1 oz, it adds negligible weight while protecting the ejection port from sand, salt spray, and particulates, making it especially valuable in arid environments, coastal operations, or high-round-count training scenarios.

The custom engraving option allows operators to personalize the cover with unit markings, call signs, or administrative identifiers for inventory control and field accountability. Field operators recognize that even minor contamination in the bolt carrier group can degrade firing reliability or increase maintenance burden between engagements, making this cover a practical addition to any AR-15 setup.
