I am interested in possibly getting into air soft or some type of reality type training. I have the trained people who want to teach me and the space to train. I was wondering who makes the best AK 47 and GLock 21 air soft or reality based weapons? What other systems are there? How accuret are air soft rifles and hand guns? What type of groups at what distance can I get? Do they come anywhere close to the real thing at 50 yards and under?
