by johnnie, from NY, United States Written on August 6, 2024
The tension spring that holds the port cover open, slipped off the receiver, and cut through the lower portion of the cover

Great part

by steel, Verified Owner from GA, United States Written on July 12, 2024
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.

I’ve used these on a couple of my builds. Very light weight and durable. I also have it on my personal AR.
