I have a DPMS parts gun about12 years old that i sbr'd a few months back and has a colt 4 position stock w/an H buffer. I did a 15 minute trigger job about 2.5 years ago with good results. But the other day after about 150 rounds w/4 shots left in a 30 rnd mag it doubled. That never happened before, i did a quick check and shot the last 2 rounds and went home. At home i checked everything and all is ok (disconnecter spring etc.).

The best i can see was that i had a bump fire, i'd rather that not happen again so what would be the best modification to make. I'm thinking of filing the front bottom of the disconnecter for more contact. Any opinions?

I checked the gap looks to be about .005 so I'll take a little off. Next time i shoot i'll check to see if it bumps too easy and go from there. Thanks Dano.
