The history of these rifles is a bit obscure as they were originally imported into the US in the mid 1990s. It is my understanding that Keng's ordered only the barrelled actions, then stocked the 522 actions themselves, in America, with walnut stocks purchased from Bishop's. The resultant rifle sold quite well, as they were relatively inexpensive and were, of course, very accurate. More barrelled actions were then ordered, but then the ban on Chinese weapons went into effect, and the barrelled actions were orphaned, winding up marooned in some customs warehouse for the next 15 years or so. Then someone in Canada got wind of those marooned barrelled actions and bought them up. The stocks they were sold with in Canada did not come with the 522 barrelled action, nor were those stocks ever intended to fit the 522 (they appear to be stocks intended for the EM-332, another Norinco rimfire rifle, which shares the basic 522 action--with a different bolt handle and a sporter weight barrel). So, the Clinton gun ban cuts both ways--Americans got the 522s with the nicer stocks, while Canadians got the guns new for far less money than used 522s are selling for in the US.
