Thanks for the replies guys. Please keep the opinions flowing and it will print a clearer picture for us people who are interested in joining airsoft.
The reason why I think rifles should be limited to semi is to allow PDW to go full auto at 300- fps. I think there should be a distinctive difference between each types of weapon, which promotes teamwork and planning. Besides, going full auto on a target 20m away is still very difficult beyond initial burst on real guns (based on my limited expereince on a full auto M4 I shot), why should airsoft rifle be allowed to go full auto since it doesn't have recoil? I just wish that airsoft is not like "who spots whom first wins" like I see on many videos.
