Go to the DPMS website or here in industry forums- post a question for DPMS. Usually Jared -a sales dude from DPMS will answer all of your questions. That is what I liked about DPMS-they helped me out. From what I heard, their Sweet 16 or one of their other 16" rifles, are very accurate-even for prairie dog popping. Truthfully, I think my 20" SST bull barrel is a little heavy. Of coures I am used to luging a standard AR around.
