BCM Mk12: true sub MOA accuracy & 100% reliability

When I received this upper I went over it with a fine tooth comb, it was absolutely perfect, not a finish mark or scratch at all. I have never seen an upper this cosmetically clean. The gas block was perfectly centered inside the DD Lite rail and the A2 flash hider is timed perfectly.
In the short time I have had this upper I have shot multiple true 0.5 MOA groups at 100yards (less than 1/2 of an inch) and multiple true 0.5 MOA groups at 200 yards (less than 1 inch) with ammo from 55gr to 77gr.
This is truly a exceptional upper, I couldn't be happier!
YOU GET WHAT YOU PAY FOR!
