Why not? OK, since you asked... Plastic abounds! Stock, magazine and bottom metal. Works, but feels exactly like it is, cheap. One action length, long, again because... cheap. So if you want a .308 or Creed or similar short action round, tuff titties, you get to feed it though a long action receiver. Odd ball floating recoil lug too. Some like it, some don't. Makes working on them a bit tricky.
So you get a cost effective rifle that works reliably and is generally quite accurate out of the box. But, if you're one, like me, who appreciates the feel and fit and finish of good craftmanship, you're going to be disappointed. Seems you are probably aware of that though, and that costs more money.
The good news is, there are lots of aftermarket part to improve them. Stocks, and bottom metal and such. Of course, by the time you factor the cost of those upgrades in, you could've bought a nice rifle to begin with, so factor costly potential upgrades into future cost, if you're the type that likes nice chit.
If not, and you just want a basic tool that goes bang and hits what you aim at, rock on with a TIkka.
