BTW, do the folding or collapsing stocks on airsofts really work?
Generaly on the higher end Tokyo Mauri, and other quality brands, the attention to detail approaches 100%. This includes removable mags, fake, but movable, cocking handles, collapsables stocks etc. Some even have metal in thier construction in the appropriate places. US customs dosen't like these "toys" very much, and even have been using copyright and trademark infringment as a pretext to sieze shipments when items say "Colt" or "Glock".
It's not until you field strip the airsoft to get at it's batteries, or remove a mag, and seeing a 6mm bb port etc. do you see any functional differences.
My Mauri FNp90 Airsoft even has fake hollow metal 5.7x28 SS190 cartridge bodies that you can see through the clear polymer magazine, and the bb's are hidden inside that. There are only two external discrepancies in my P90:
1. Under the magazine well, where the FN's turntable loading mechanisim would be is just a 6mm bb port, and it's mate on the magazine. (all hidden when loaded)
2. Under and inside the rear pistol grip where the bolt and ejection port of a real p90 would be is a sculpted piece of plastic that dosen't move.
Otherwise it is externally identical in all other respects.
