Lower Reciever compatibility AK
 

Are the Ak 47 and 74 lower reciever the same for fixed stocks?

No. What parts are you trying to do what with?

Cyma AK74M lower is plastic. Want to upgrade it to a metal one

So it has a side folding stock then?

Is it a CM031? I am assuming it is, as CM040 seems to have only metal receiver and side folding stock.
CM031 and CM040 (both CYMA AK74M) have very different receivers. CM031 is Marui-spec and CM040 is VFC/LCT spec.
With either model, it will probably be very diffcult to get a metal receiver in Canada. Same applies for AK47 receivers.
If you are getting an AK47 receiver for that, saying a receiver from CM042 or CM028 (both Marui-spec CYMA AK47), be aware that there is an extra piece of metal at the grip end on CM042/CM028, which can probably be cut. I am not sure if everything else is the same among CM042 and CM031 receivers but they should be very similar.

If its me, unless I can get the said metal receiver very cheap (saying scavenged from a "dead" gun), or the gun means something special to me, I wouldn't bother trying that. I would sell the CM031 and buy a CM040 instead. CM040 also has nice steel receiver, instead of pot metal receiver from CM042 or CM028.

Evike has them.

I have been away for a while... Is Evike (and their UPS shipping) still a pain as they were, when custom brokerage fee goes?
Also I don't think that can be imported easily.

If you order an AK lower receiver from outside Canada, it's going to be seized at the border.

Order though hero
