For the BCM/Geissele, the only thing I can think of for that insane deviation with the bipod prone shoot was contact with the gas block with maybe the bipod mount back-end hardware. Because it went right back to close POA=POI for the tripod-supported.

Excellent video to illustrate what we’re talking about with positional POI shift though.

The rifle that has me the most curious is the Hk G28, because it uses a steel upper. Would be interesting to see if it holds more true than all the aluminum uppers.
