Looking back, I believe, as do many,  that the Obama years desire to change or do away with the Second Amendment had created such a scare across the country, for nearly a decade, that powerful and overwhelming and unprecedented buying of ammo and guns that the firearms industry became wealthy indeed. See this Forbes Article below.

The industry however took much of those earnings and reinvested in state-of-the-art rifle and pistol tooling equipment and in some cases began 24 hour three shift operations to keep up with demand.

This retooling perhaps is evidenced by American Manufacturers with lower prices, improved accuracy and the ability to mass produce that is unprecedented.

The use of new Hammer Forging tools, for example in barrel making, has made volume and quality significant and has reduced costs measurably as well as molding technology.

I have tested Ruger and Savage Rifles and found costs below average and quality and accuracy far above average. Further, that synthetic stocks are dominating the market for rifles, but not just black in color but all the colors of the rainbow and camo patterns that are beautiful. 

This is a golden age for buying a new rifle, shotgun or pistol/revolver

Ammo costs are equally low today so stock up my friends.
