The Bastion AR Ejection Port Cover "Don't Tread" is a precision-manufactured retention cover engineered to seal the ejection port against environmental contamination. Built by Bastion Gear, a manufacturer known for exacting tolerances and durable AR platform components, this cover provides operators and range shooters with a reliable way to protect the chamber and firing mechanism from dust, debris, moisture, and fouling when the rifle is stowed or transported.
Manufactured to tight specifications, the ejection port cover features secure fitment and positive retention on standard AR-15 upper receivers. The compact 3.25 x 0.5 x 5.5 inch profile adds minimal weight at just 0.06 lbs, making it practical for field kits, duty bags, and range transport without noticeable bulk. Bastion's precision engineering ensures the cover seats flush against the upper receiver, preventing rattling and unintended displacement during transport or storage. The durable construction withstands repeated installation and removal cycles without degradation to retention or fit.
This cover is ideal for shooters who store rifles in challenging environments—coastal ranges subject to salt air, desert operations where sand infiltration is a concern, or duty situations where extended storage between deployments requires barrel and bolt protection. Law enforcement, military personnel, and civilian operators who practice regular maintenance recognize that exclusion of foreign matter reduces cleaning time and extends component life. The AR ejection port cover serves as essential preventive equipment for anyone serious about firearm longevity and operational readiness.
Bastion components are recognized across the tactical community for holding tight tolerances and consistent fit on mil-spec AR platforms. This ejection port cover is a straightforward, proven accessory that pairs well with complete upper receiver assemblies and standalone builds. Stock one for each rifle in rotation, or maintain spares in your maintenance kit to ensure coverage is always available when needed.
