You didn't ask me but as I recall, you simply extend the bolt from the carrier, (as you would do before reassembling the rifle), and stand the BCG vertically on the bolt end .
If the bolt slides back into the carrier under the weight of the assembly, the theory was that the gas rings needed changing as the seal was not tight enough.
