1) Army Issue in Port Credit is the only local Bastard that I know in that area, he is also an AV rep so you can get those two things done at the same time.

2) Since those aren't really restricted parts or anything you can get them from anywhere, redwolf, ehobby, airsoft extreme, the war store, airsoftparts, etc. However keep in mind that airsoft parts you can pretty much just do a pickup

I would probably go with Prometheus, Mad Bull, or Modify. Just pick a spring that will get the FPS that you want. Around 380 FPS is probably what you should be aiming for. Remember 400 FPS is a limit not a goal.
