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 precision-machined cover snaps securely over the ejection port opening, providing a critical layer of protection that extends the service life of internal bolt and carrier components.

Built for AR-15 platforms, the ejection port cover offers reliable retention without requiring additional tools or permanent modification. The custom engraving option allows operators to personalize the cover with unit markings, call signs, or administrative identifiers for inventory control and field accountability. Measuring 4 inches in length with minimal profile, the cover remains accessible for rapid deployment if needed. At just 0.06 lbs, it adds negligible weight while protecting the ejection port from sand, salt spray, and particulates—especially valuable in arid environments, coastal operations, or high-round-count training scenarios where bore fouling directly impacts reliability.

This accessory serves duty-oriented shooters, military units, law enforcement teams, and serious sport competitors who prioritize weapon longevity and operational readiness. Field operators recognize that even minor contamination in the bolt carrier group can degrade firing reliability or increase maintenance burden between engagements. The ejection port cover is a low-cost insurance policy that fits seamlessly into a comprehensive rifle maintenance philosophy, allowing users to keep rifles in ready condition without constant cleaning cycles. Spike's Tactical reputation for precision parts manufacturing carries through to this cover, ensuring consistent fitment and durable custom engraving that withstands field handling.
