The good news for you is that 487 FPS with 0.12g is still within the outdoor limits at most games around here, as the terribly critical measurement is the energy in terms of joules. Being as the limit around here is generally 1.49j (0.20g at 400 FPS), your gun is shooting about 1.32j, given a 0.12g at 487 FPS. This is roughly equivalent to a 0.20g BB at 385 FPS. So, your gun is about the same as any other stock AEG out there.
That being said, I would probably trust a chrono long before I trusted the measurements posted on the box.
So, uh, welcome aboard, read the stickies, be nice to everyone, and we look forward to seeing you at a game.
