5 of 5 Awesome in everyway February 27, 2020
Reviewer: Timothy Pettis from Silsbee, TX United States  
I have had my upper for over two years. I have shot many different rounds to find what it like better for accuracy. So far great. I have not had one malfunction at all.
I am keeping nice tight groups out at 150 yards. Roughly 1.5 inches. The .300 rounds drops like a brick so I am very impressed.
I use this upper on my hog hunting gun. So i go into swamp and heavy brushed areas and the finish is still perfect.
I absolutely 100% in anyway shape or form recommend this upper for anyone!
