Considering the cost of the X95 and WK180, they had darn well better be ranked higher than the WK180. At roughly 3x the cost, anyone would be seriously pissed if their rifle wasn't better.
The question is, for the money, is the WK180 a worthwhile purchase? Given the parameters of a $1200 rifle I think the WK180 is an excellent value. Yep, its had some teething problems but then some rifles costing twice as much have teething problems too.
The WK180 is a decent product at a decent price. It is not a military spec rifle and it prob won't stand up to huge amounts of abuse but then anyone who thinks they can get a MIL spec rifle that will last forever, for $1200 is a dumbass.
It is one thing to rank rifles for quality etc but we all have to buy these rifles with our own hard earned money, so ignoring the cost of each rifle is foolish. Both cost and quality are important factors in a purchase decision .... hence the proliferation of the SKS in Canada.
