In late June I started comparing both platforms to see how the shooting with the ST22 reflects on my shooting w/ the AR. I started by confirming my POI at 100yds w/ the ST22 and CCI Blazer ammo: I did the same w/ the AR and zeroed it about 1" high...no pic *curse the gods* Then I checked the POA w/ POI at various distances to see the variation between the two. Left side was shot w/ the Spike's Tactical and the right with my Armalite M-15A4C, both using a red dot sight. Three shot strings except at the 100. Everything seems to jive fairly well, the 50 is the biggest difference with the ST22 impacting about 3" high vs the M-15A4C. Shooting at center mass body though, it will not be enough of a variation to require a different aiming point.
