Bastion Ar Ejec Port Cover 300 Aac

The Bastion AR Ejection Port Cover 300 AAC is a precision-engineered component designed to seal and protect the ejection port of AR-pattern rifles chambered in .300 AAC Blackout. This specialized cover prevents dust, debris, and environmental contamination from entering the bolt carrier group and internal operating surfaces during storage, transport, or field operations, making it essential for operators in challenging environments.

Manufactured to exacting tolerances, the Bastion ejection port cover ensures a secure fit that minimizes movement under recoil or tactical maneuvers. Its compact dimensions of 3 x 0.5 x 5.75 inches allow for seamless integration into standard ejection port geometry without obstructing charging handle operation or adding unnecessary bulk. Weighing only 0.06 lbs, it imposes no ballistic penalty while providing essential protection.

This accessory is ideal for law enforcement tactical units, military operators, and serious civilian shooters who require reliable weapon performance. Whether staging a rifle between range sessions or preparing for deployed operations, the ejection port cover helps extend the service life of internal components by reducing contamination. Its design is particularly beneficial for those utilizing suppressed .300 AAC setups, where meticulous weapon maintenance is crucial.
