You tried to import a prohibited device (the receiver) and it got caught. It does not matter is you've done it before and never had an issue, you got caught this time. Basically, you have to contact CBSA and explain why you think you should be allowed to import a prohibited device without appropriate permits. I'm presuming you do not have the proper permits. All the other stuff is fine, they just seized it because. The receiver is gone though.
We have an entire thread on Importing Airsoft and the hazards of just ordering whatever you want.
I've already deleted several replies that were insulting and not helpful. Please stay on topic and be civil or infractions will be handed out.

No suppressor listed in that list. A fore end yes, no suppressor.
