Contrary to popular belief, the 'stocks' of most production rifles, especially the synthetic units are not the downfall of the rifles accuracy.
The cost cutting measures employed by many of the mainline firearm production companies are the reason accuracy evades us today.
Most of the production firearm companies, decisive, upper echelon, are young in comparison to the decision makers of the days when 'less than an inch at 100y' was the norm, or the maximum allowed spread a rifle could be expected to yield.
The mindset today, within the management of these companies, is centered on profit, not exceptional accuracy, and by all rights, this is what the general shooting public is reflecting to the manufacturers, it is not so much the accuracy that is important to the majority of today's shooters/hunters, but cost of the particular rifle....and whatever it produces as far as group size is OK by them, shucks most of these same folks don't know if a 3'' group at 100y is good or bad!
The same can be said concerning the 'quality', or looks of said firearms, these firearms may look horrendous by yesterdays standards, but is fine and dandy by today's standards as long as the price is not 'up there'. And the manufacturers are certainly taking advantage of this!
We should all be happy that one of the 'big boys' in the production world has not figured out how to make a polymer rifle! hehehehe
