UPDATE
Went to the range today with a fully functioning AR15 and begin to swap parts. I tried every combination of BCG, Bolt, Upper, Lower possible and discovered that the Nordic Barrel was NOT at fault. I back this up by going to Rose Action Sports and re tested everything. Together Steve Rose and I discovered that some how, some way the VDI Low Mass Bolt Carrier is out of spec. Rifle functioned perfectly with a full mass spikes BCG, even with the VDI bolt in the Spikes BCG. No combination that included the VDI Low mass carrier worked. We removed the gas key and there were no obstructions and it was properly staked down. The exact reason will be a mystery but atleast I discovered the problem.
