Previously I hadn't really been lubing up the magazines at alkyl, but the last couple if matches I made sure to do that but still had a couple rounds ruined by the FTF issue.Are you getting enough lube on the spring guide rod. I find I need to put a drop or two on it to have it cycle completely and that is where the majority of the friction is during function. The outside of the bolt has next to nothing that it touches so I just lightly coat that. Last match I started to have some cycling problems. Opened it up dropped a drop on the rod and function was 100% again.
Of course, last weekend when I was at the range and not competing I didn't have single problem at all. I think it just doesn't want me to win. :-)
