I have a POF308 with a 20" barrel which is generally considered one of the best AR-10 out there. It is a great rifle for multiple targets (pigs). It cost me $2,600 a few years back.
Having said that, I will say that my Savage 10, also a 308 is much more accurate. At a 100 yards the difference is only about 1/2" tighter groups but at 300 yards an beyond the Savage with a 24" barrel can still 2-3" groups and the POF spreads to 6-8". I consider myself an average shooter, so other could probably do much better. The kicker is that the Savage only cost $830.
Unless you got some dollars to indulge yourself the economics speak for themselves.
