Now for Airsoft: When I was unpacking I was pleasantly surprised it is very good in the hand (because it is difficult), is very well finished and has such a force that it shot smoothly through a newspaper or plastic geht.Ich even think the are far more than 0.5 joule!
The size I quite OK, and the magazine capacity is 17 with balls is not bad.
However, I would hard BBs with 0.20 - 0.25 g recommend.
I can only Weiterenpfehlen because I am really convinced and you will probably be there.
