CMMG MK3 3GR UPPER

by ACIDKOOL, Verified Owner from CA, United States Written on December 14, 2015
Upper is great and light considering this is a AR10 platform.
I built the lower(CMMG) from scratch and the fitment is perfect, no gaps between the lower and upper. Also this upper comes with the BCG. I didn't read through the whole thing and ended buying this and the BCG separately and ended up returning the BCG once i found out the upper came with it.
Pros:
  • Fitment is Perfect
  • Light for a 308 Upper
Cons:
  • None
Would recommend: Yes
