Ever since I sent my MCX in for the new BCG, I've been kicking myself. Before I sent it in it ran flawless, but since, I can't get thru a full magazine without multiple FTE. I've already sent it in once, and they said they replaced the gas block and ran three mags thru it with no problems. I had high hopes that they found the problem, BUT noooo. I went to the range yesterday, and it started again multiple FTE in the first magazine. I've tried different companies, different grains, different shooters, and still have FTE. So, I guess I get to send it back to Sig Sauer again. Is there anyone else who is having the same problem? I really enjoyed shooting it before the recall, but since not so much. I've tried different gas block settings, I've tried a POF roller cam pin, and still no good. With all that said, I also run it pretty wet. Does anybody have any suggestions?
