Last time I shot it it was shooting around 1 moa for a 10 shot string with my my 155 gr sierra palma or 175 gr SMK loads. IT took quite a while for the rifle to settle in, infact I called DPMS as I was not impressed with the accuracy when it was new, they told me to put 100 rounds through it and see if the groups tightened up and the rifle did exactly what they were predicting it would. In my opinion, 1 moa from an 800 AR is pretty respectable. I am sure with some taylored ammo and a better shooter used to the AR platform could do even better.
It will not run with a $3000 custom made AR-10, but it will shoot moa and will save you $2200 as well!!!
