    What brand of lower did you put the trigger in?

    I don't believe this applies to the current situation unless I misread read what he did. I also don't think the pins are the problem.

    Your not taking the time to troubleshoot the problem down to the exact part. As you have a functioning FCG in now, put the parts that were causing the fire on release malfunction back in and change them out individually with the known good parts in the following order, performing a proper function check between each change:

    Disconnector Spring
    Disconnector
    Trigger
    Hammer

    You will quickly isolate the offending part. It doesn't matter that one set is an ALG and one isn't.

    Knee-jerk is the disconnector. However, this is very sound advice when experiencing any sort of parts problem:

    I am very impressed with ALG’s customer service. I already received a response from them on the issue of my rifle firing on trigger release. They said that they suspect a problem with the trigger and are sending me a replacement tomorrow. Can’t ask for better than that!

    I have several ARs and tried an ALG in my Colt. I never got to the point of shooting it, since the trigger wasn't resetting properly. I ignorantly forgot that particular Colt was a post-ban large pin model, and ALGs are only small pins. The difference in pin size is really small.

    That's what prompted my question about the brand of lower you put it in.

    Just thought I’d post that I took the other AR that I installed the second ALG set in out to the range to test. I put 120 rounds though it and it fired perfectly. I was also able to get it sighted in as this was the first time I shot it.

    I am having the same problem as OP as well. But I used all the parts ALG provided including pins. I followed Bill's video during installation an also did safety/function check on the rifle before I hit the range. I was able to fire the first round, but got nothing on the second shot. This was installed on a Mega Arms lower receiver.


    Sounds like I should contact ALG as well
