I have heard from many, that the Ruger American was too cheap feeling for them. But, the two I have not only shoot well, but as plastic stocks go, they feel pretty decent, and with the aluminum bedding blocks they are sturdier than many other synthetics.
The Marlin x7 rifles I own had to have a replacement stock to shoot well.
A nice laminated stock goes well with most EL Cheapo rifles. Boyd's seems the best for the price.
The fit and finish isn't what I want on the 700 models that sell in the affordable range. But probably the best base rifle out there on average, for price, accuracy, and especially for aftermarket parts to spruce one up your self.
The AB3 is not one I have owned, but I have shot several. The accuracy is decent, but the triggers all need work, via a spring kit.
Of those on the list my top picks would be
#1 Remington 700
#2 Ruger American
#3 Tikka
The Tikka has good accuracy, but little aftermarket help compared to the other two. And it seems awfully light for caliber too me, on the rifles I shot in 300 wm.
But, the price on the few I see locally seems more on average than the Remington or the Ruger.
I'm sure price varies from region to region. Tikka is less popular in my area for some reason.
