I'm considering a Pof edge 308 18" as my first semi auto 308. I'm looking for something that will shoot sub-Moa. Will these rifles shoot that well, or do inneed to look at a lmt/Larue? I've also considered building a rifle, with top quality parts. So right now I'm all over the place, but the piston POF peaked my interest. The rifle will be run suppressed 90% of the time.
