I had an MP10, works 1.5 - 2 MOA gun call smith ask them what you should expect. DPMS Gen 2 Hunter, not even one box of shells thru it, sent it back they returned my money, could have just been that one gun, lots of people like em ask rickiD how his is working, Ruger 762, heavy, must replace the trigger, shoots 1MOA or better, works.
