Ratings & Reviews
No regrets pleased customer

I was on the fence between multiple upper receivers to purchase but always came back to this CMT. I was unfamiliar with this company as there is not a whole lot of data online about them. I am confident this complete upper is a work of art that will last a lifetime. It has performed flawless through 150 rounds so far and mated to my Anderson lower with no play between at all. The CMT website states this upper is rated for full auto. The only nit pick I can state is the BCG is not MPI or HP tested.
