Most Helpful Positive Review Quality product
This is a quality product that you would expect to get from a company like cmmg. The machining is flawless inside and out. The finish is also vey even and smoothe and a very nice deep shade of black. I don't think you will be dissapointed this upper.

My upper receiver

by Meg, from KY, United States Written on July 11, 2020
I love it! But I was hoping they’d send me a sticker. I didn’t get a sticker. Other than that I love it. It took awhile to ship, which was understandable given the events in 2020. I will definitely continue purchasing from Optics Planet.
Pros:
  • None
Cons:
  • No sticker
Would recommend: Yes

Great choice for a build

by Biggs, Verified Owner from GA, United States Written on May 11, 2017
I ordered this and paired it to a PSA lower. The fit was great. The finish is a little more matte than the lower but only on really close inspection. No play between the upper and lower. Everything fit together well. I am very pleased with it and would definitely recommend it and purchase it again
