Many AR style .22s have very little in common with the weapons they are mimicking. Some are closer than others, but anything designed strictly for .22 LR use will not be set up in the same manner. Blow back vs. DGI, the starting points are just different. It's like trying to get a VW kit car to learn about a Ferrari. There are some similarities, but not many, and they tend to be superficial.
