Built around a \u003cstrong\u003erigid polymer\u003c\/strong\u003e dust cover, this kit offers a clean look and rugged durability while shaving weight over a traditional stamped metal dust cover. Designed as a drop-in replacement for mil-spec AR-15 upper receivers, it keeps debris, dust and fouling out of the ejection port and action during storage and handling.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eManufactured by \u003cstrong\u003eCMMG\u003c\/strong\u003e as part of their ZEROED line of build and upgrade components, the \u003cstrong\u003e55BA6C8\u003c\/strong\u003e dust cover installs in place of the factory ejection port cover and uses the standard spring and detent hardware found on mil-spec uppers.
