Scott's Review of Primary Weapons Systems MK1 MOD 2 Upper Receiver

Yes the caps lock was necessary in the title. This upper is an amazing piece of hardware and well worth the price for what it delivers. I have about 6000 rounds thru it already and not a single malfunction, maintains sub moa groups even when heated up o.O couldn't ask for better
