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.

Liberals are constantly telling us about the poor and oppressed in this country. With that in mind, why do they feel the need to keep importing poor people from other countries?
