I don’t really leave reviews that often. But this upper was perfect in every way . It was my sons 1st build and he picked it out . Shipping was fast and the fit was perfect. He was happy and I was amazed with the price and what you get . Quality to the fullest.

5 of 5 Excellent Product July 22, 2022
: Justin Weeks  
I am really pleased with this product, great fitment and a quality manufactured item. My shipping seemed to have taken longer than normal which is no reflection on mas defense, I had emailed jr and had a return email within 24 hours. Great customer service.
