Gucci build's Review of CMMG Mk4/AR15 Upper Receiver Assembly

I’m starting a build and decided to choose Cmmg because I already have a Cmmg lower. This lower is a perfect match with no wiggle and looks good with the tungsten grey lower. I’ll be doing a 5.56 10.5 so wish me luck.
Pros:
  • Perfect fit. Good price. Rear charging handle
Cons:
  • None
Would Recommend: Yes
