i will attempt to explain the airsoft appeal to you guys since i own both and use them.
airsoft was made in japan for folks that wanted to own a military style(preban if you like) in a country where the ownership of almost any weapon is illegal for a civilian. and they make copies af anything used by militaries or police organizations for those weapons so just like we have a million variants of the ar they did the same for airsoft.
now the important thing to remember is that that is the closest most japanese will ever get to owning a real gun so it isnt surprising that they will spend that much on them.
now to the u.s. the draw here is that you can play simulated wargames(although much closer ranges) with full auto weapons and dress up in camo. simply put we dress up in camo wear all the web gear and play war. it gives you a bit of a rush actually being under fire, communications, and unit cohesiveness and unlike the real thing everyone goes home intact at the end of the day.the farthest range that some of these guns have is about 100 yds and they are more or less accurate.
its quite different than shooting at a target that you can take your time to make sure you can put 5 shots in a dime at 100 yds.half the time youre shooting at a target you cant really see and is shooting back at you.besides when was the last time you set up an ambush with a few oter guys and killed off a dozen people and watched as the remains of a viable force retreated in disarray?
