AK and their clones are prohibited in Canada.
A Russian sks runs about $275 with the Chinese version less
If you watch for deals you can pick up 1100 of fmj for about $125 for the SKS.
A mini 30 used will run about $800 so I would rather buy an sks then get a synthetic stock for it.
My nephew's sks was in very good shape when he bought it and he has had fun with it.

I used to own a mini 14 but sold it because I didn't have a use for it, now I wish I had kept it
