The point being missed is that these inexpensive rifles are quite often as accurate as rifles costing 3 or 4 times as much....as to people saying they will not survive long term usage as compared to more expensive rifles, will I've got a 30 year old 788 thats in every bit as good of shape as any of my run of the mill Remington 700 bdl's, winchesters, brownings or rugers. If you don't think they (cheap rifles) will take abuse you should review Jerry's (Mystic Precision) savage axis torture test. Try that with a one off full blown custom and let us all know the results.
The hunting and shooting sport needs rifles that have acceptable accuracy and reliability to be priced low enough, to attract new comers if we want this sport to survive....these rifles may not be of Mark V, Cooper, or Sako fit and finish but chances are they will still be hunting and taking game 50 years into the future and for 450 dollars, that sounds like a pretty good deal to me!
Happy hunting.
