Overview
The Black Rain Ordnance Ejection Port Cover Assembly is designed to keep debris out of your AR-15's action, ensuring reliable operation. Made from 6061-T6 aluminum and featuring a sleek black finish, this dust cover not only protects the internals but also adds a streamlined look to your build. This component is commonly found in mid-length gas system builds chambered in 5.56 NATO, making it a practical choice for those setups.
