Yes, it will work with Aero's M5 uppers. We highly recommend head spacing the bolt when building an AR-10 piece by piece.

I, purchased this BCG to install in a M5 upper but the BCG won’t move into the home position because the gas key and gas tube doesn’t match up with the gas tube. When installing, the BCG will stop at the point where the gas tube and gas key meet up. 1/2 inch short of the home position.

Yes, it will work with aero M5 uppers. The first trybe bcg optics planet sent me had to go back, I could not pinpoint the issue but it would not fire. The second one works just fine with my aero upper and ballistic advantage 6.5 cm stainless fluted 20 inch barrel. I installed aero gas block and aero gas tube. Had zero issues with the second bcg functioning. Even though I put my upper together it is all aero/ballistic advantage.
