My brother has a DPMS, I think it's the Oracle, that has run great. He has put a lot of rounds through it in a short period of time and it has run flawless.
If I were to buy an AR it would probably be the Sportical because I don't really have a need for the forward assist.
Like others have said the trigger is not the greatest. The trigger on my converted Saiga is much better then his Oracle.
We have not been able to really do much with accuracy because he had a Bushnell on there that he bought with the rifle that he kept trying to use. That thing was crap. I finally talked him into ditching it and getting something better. I hope to sight the new stuff in next Friday and then really see what it can do.
