and no more FTEs after SAI replaced the extractor, pin and spring! arty: I am now 100% confident in the abilities of my M40-A1 and trust my life behind it. I've also started improving my accuracy in a strange way. I seem to do a bit better by not lining up the sites and focusing on them, just focus on the X with the top site slightly out of focus. Now it's time to start reloading because I've blown through 700 of the 1k rounds I got a month or so ago.
