I absolutely love this upper!!! Lightweight and appears to be well constructed. Have only shot about 120 round through it but it seems solid

Very accurate and matched up perfectly to the PSA MOE ept lower I got with it. I'm getting solid 1moa at 100 yards with federal m193. The nickel boron bcg cleans up very easy.
Functions flawlessly, looks amazing

The charging handle was not ambidextrous.

This was far more than I was expecting.Fit and finish are good, everything's nice and tight and stays that way. Averages about 1 MOA with standard federal 55gr 223. No malfunctions in 400 rounds and that Nickel Boron BCG literally wipes clean. no problems mounting optics or accessories. At this price, i feel like buying 5 more, never mind what my wife thinks.

Impressive Accuracy plus Quality
Ok here it is. After 300 rounds of American Eagle 5.56 and then zeroing it at 100 Meters. I am happy to say I am getting from Sub MOA to 2 MOA. In the desert on a wabbly table, with a bi-pod. If I had used a fixed platform such as a pay to play range has, I'm sure all groups would of been Sub-MOA. PSA Your Freedom barrels really surprised me and impressed me.
