To the OP, I have a Springfield M1A Scout and no, I don't regret it. But you have to know what you are getting into with M14-style rifles. The basic design is 60 years old and inconvenient to accessorize or modernize. Every change you make to the rifle seems to cost like 2-3x more than it should. Actually, so does the rifle itself.
I got the M1A not because it was the most cost-efficient or effective choice, but because of the old-school coolness and classic looks of the design. When judged on those criteria, it's the best rifle in the world. When judged on reliability, accuracy, and all-around practical value, it's still a good choice, just not the best as many would claim.
