Decent upper. The M-LOK slots are not true spec measurements, which was a big disappointment for me. The rail feels weak when you C-clamp it, as if you can crush it with your bare hands (you can’t). The finish is great and the gas tube and overall fitment is in good condition. The rail I received doesn’t look anything like what’s in the display photo. Shipping was normal wait time 3-5 days.
