CMMG 55BA6C8 ZEROED Polymer Ejection Port Dust Cover Kit AR-15 Black

The CMMG ZEROED Polymer Ejection Port Dust Cover Kit is a lightweight upgrade component for the AR-15 platform. Built around a rigid polymer 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.

Manufactured by CMMG as part of their ZEROED line of build and upgrade components, the 55BA6C8 dust cover installs in place of the factory ejection port cover and uses the standard spring and detent hardware found on mil-spec uppers. The matte black polymer construction resists corrosion and wear, making it a cost-effective option for custom builds, replacement of lost or damaged factory parts, or as a simple visual upgrade for an existing rifle.

This listing is for the dust cover kit only and is intended for the AR-15 platform. It is a non-serialized accessory part and ships in new condition, ready to install on a compatible mil-spec upper receiver.
