My choice would be a T/C Venture. It has a great trigger, 5R rifling, and a 1moa guarentee. You can get them here in my area for just over $400.
Just stay away from Savage Axis/Edge and Remington 770
Why is that?. I had the Edge and it would out shoot most guns 3 times its cost. Very accurate rifles and very nice price on them also.
That really limits what you can do with it as far as customization.
Any of the high-quality aftermarket stocks for one. Also probably out would be any kind of bedding job, although somebody may figure out a way to do that with their stock configuration.But, exactly what customization does the recoil lug preclude?
