Bastion Ar Ejec Port Cover Molon

The Bastion AR Ejection Port Cover in Molon finish is a precision-engineered accessory designed to protect the critical ejection port area of AR-platform rifles from environmental contamination and debris during storage, transport, and tactical operations. This component addresses a fundamental maintenance concern for AR operators: keeping the bolt carrier group chamber and surrounding internals free from dust, sand, moisture, and particulate matter that can degrade reliability when field conditions are harsh.

Engineered with precise manufacturing tolerances, the ejection port cover provides a secure fit that doesn't require permanent modification or complex installation. The compact profile measures 5.5 inches in overall length with a minimal depth of 0.25 inches, integrating seamlessly with standard AR-15 and AR-10 upper receivers without interfering with charging handle operation or sight mounting. The Molon finish offers corrosion resistance suitable for extended field deployment, including humid or salt-air environments common to coastal training areas and overseas operations.

At just 0.06 pounds, the accessory adds minimal weight while delivering measurable protection to the firearm's most exposed internal passages. This ejection port cover is essential for law enforcement patrol rifles, military training systems, range guns stored between sessions, and civilian AR platforms exposed to varied weather conditions. Operators transitioning between indoor and outdoor shooting environments will find this product invaluable for maintaining firearm reliability.
