Great part - CMMG ZEROED AR-15 Polymer Ejection Port Cover Kit

I’m increasingly impressed with CMMG parts like this. I wanted a polymer ejection port cover so it wouldn’t scratch the anodizing off the upper. I wanted one that mimicked the design of an original cover, while using original style hardware. Polymer covers seem to be the modern way big names are going, and this one fit my needs at a great price.
