Greylocks: I called the CFC in Ottawa and talked to a "firearms analyst" who is specially trained in modifications to firearms which the agency noted was a "finicky" subject. (Only in Canada eh?)

He (Andrew) said unequivically that there is no legal prohibitions on adding a BB gun part to a firearm (so long as it is not a prohibited device in itself i.e. a flashhider or bullpup stock).

I told him I heard that it was illegal to add a part to a firearm that was not intended for a firearm, and he quipped in a French accent: "I don' know where you got dat."
