Magpul MBUS Pro Back-Up Sight – Front
The Enhanced Ejection Port Cover is a drop-in upgrade designed to provide an improved installation process, physical strength, and corrosion resistance over the standard USGI ejection port cover. Traditional stamped-steel ejection ports are malleable, prone to corrosion, and require tools to install. The Enhanced Ejection Port Cover snaps into place easily on forged Mil-spec uppers without having to remove your hand guard or barrel nut, wind any loose springs, or adjust small e-clips. Constructed of impact-resistant injection molded polymer, it is corrosion resistant and will not bend or deform from impacts.
