Airport security is very tight since 9/11, and people at airports don't play around with things that they don't understand. Airsoft guns are a definite no, no; but the BB's is a tough call. Best to err on the side of caution - you probably can have the BB's in your luggage, but do not take them onto the plane with you.
Not a good idea. Airsoft guns are replica's of actual guns and most good ones are very realistic. Since 9/11 and all of the tightening up of airport security you can get into a lot of trouble for having one with you on a plane. But you may be able to pack it in your luggage in the cargo area. I would check with the airline first to make sure before bringing it with me to any airport.
Airsoft bbs are made up of plastic and are 6mm in diameter and are .24 cal, BBs however are metal and are .177 cal (4.5mm)
Type recommended by the maker of the airsoft.
The stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.
no it would break the gun or get jammed in the gearbox or somethin
airsoft uses 6mm bbs. Perhaps you are talking about weight? .20 gram is good.
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
yes they are very accurate
.25 Airsoft bbs can be good. Their weight is very good for accuracy and helps for a harder hit from the bbs. However, no bb is good if they are not high polish. Companies like Madbull and Matrix make good .25 bbs.
