I've been looking into a semi-auto chambered in .308. Primary use will be hunting but also want a decent target rifle. I have a qd mounted scope for my ar15 that I can swap back and forth depending on what I'm hunting. The M&P 10 looks promising since it has an 18" lightweight barrel, midlength gas system and accepts Pmags. I know I don't want a bull barrel since I'll be taking it into the field. Any opinions or suggestions? I also have a box full of milspec AR 15 parts so no need for a decked out rifle from the factory.
