I wanted to put several thousands of rounds through this upper before reviewing it. This upper in regards to the Cerakote finish, weight and overall quality is excellent. I have never had major issues from the upper, I've ran this barrel several hundreds of rounds in one trip and the range and accuracy never suffered. She does love 69gr-77gr rounds best and will easily do MOA or sub MOA with good placements. I will be buying more for the price!
