This trigger is amazing, but don't buy till they got some bugs worked out - Mimtac Drastic AR-15 Drop-in Trigger

This trigger has a reset unlike any other and it's incredible, but I ended up getting a binary setting, so I contacted mimtac and they said to just tighten the set screws. So I did and the problem seemed to go away, but after 4 mags the gun literally shot full auto.. Like 15 rounds.. Dumped the rest of the mag. It was fun at the time! I'm not complaining! Lol but that's a no-no as far as safety goes so now I gotta tighten the screws again and hope it doesn't happen. This kind of a thing shouldn't be the case and I fear that maybe mimtac has some more R&D to do. I really believe in these guys and I want them to make the best triggers on the market but until they fix this I can't. And I'm writing this after I just ordered 4 more triggers...
