I picked up one of these the other day in a .243. For an economy gun, they are not a bad buy. The fit and feel is pretty darn good for this rifle. I then mounted a cheap Bushnell 3 X 9, 40MM scope with Leopold rings. Cabela's mounted the scope and bore signed it for me for free.
My first shot on paper was only a couple of inches off. After a few adjustments, I was able to put three shots into a 1 1/4 " circle. I'm sure that if my shooting techniques would have been better and perhaps with a better shell load, the circle would have been smaller. Maybe a little adjustment on the trigger would have also been beneficial.
So, if you are looking for an economy center fire rifle, IMO the Ruger American is not a bad choice.
