I don't see any reason why you would want a DA/SA rifle.
you have two separate trigger pull weights meaning that you have two different levels of accuracy. I have seen very few rifles with 12 pound triggers and nobody I know would want one with a trigger that heavy. the SA would be right in line with a lot of factory hunting rifles but 5-7 pounds is hardly a good trigger in itself in regards to rifles.
I guess it would be something different but you would need some method of recocking the hammer which means something is flying back right towards your face. you think beretta bite sucks when it gets your thumb? wait till you slice off a chunk of your nose.
