    Fantastic Upper!

    Posted by Tim on Dec 25th 2020

    This Is a top notch upper. The barrel and bolt carrier are made from the materials you want. The smaller gas port works great with standard 556 rounds. Recoil was super low. Fit and finish is great. The price point is unbelievably good. I am very happy with my purchase!
