I don't know how many were created but......just to warn you the older guns will work if everything is top notch but most by now will not be lol. Unless you buy one from a die hard alien fan you'll probably have trouble with it because they can be a bit tempermental and the average person won't know how to solve most of those issues.
I'd suggest you grab anything 09 and up. Parts are more readily available and they're of much higher quality construction.
EDIT: For the record.....my old alien remains with mac noid was a deadly deadly gun lol.
Etek 3LT grey/black f/s
Valken Proton greyish/black f/s
68 4500 PE stubby, LP output f/s
68 4500 AIR tank(no reg) f/s
Creed Battery, eyes and noid f/s
