BB's Review of Aero Precision M4E1-T 18in .223 Wylde RM15 Complete Upper Receiver
Received this product in April. When I finally got out to the range, rifle wouldn't cycle.
After replacing the gas block with an adjustable gas block (and making sure the gas port was aligned), I brought it to the range a second time - ran through the gas block adjustment starting at full close.... at 3/4 open it finally threw brass, at full open it still wouldn't lock the bolt back.
I'm thinking the gas port in the barrel is out of spec. One way or another, this upper isn't performing as it should.
