I like that. It gives you axial and clock location.
I still determine the clock location with trouble-shooting the mounted gas tube and block with the upper receiver upside-down and a stripped bolt carrier and key.
The clock location gets determined by the position where the gas tube doesnt bind or clip the carrier key with the receiver upside-down.
You do it upside-down to simulate magazine cartridge stack pressure up against the carrier.
