I have one ,Bill. Have it for two years. I don't shoot it too much.I use 5.56 Winchester 55 gr.I have touched base with one of the reps before I bought it and he said to brake it in and I would not any problems.I kept the all the parts in the receiver well oiled with DMPS oil and fired one shot and cleaned the barrel after every shot for 20 rounds. It is a hassle and time consuming but in the long run it is worth the accuracy.I do this with every rifle I buy but make shur you keep the bolt lubed well during brake in. I like my DPMS Panther Arms Orical for the price can't beat it..
