i went to the range with my mega lower i built and my M4 upper from BM. the problem i am having is it will fire the first round load the second round but it won't fire the second round? it seems the hammer isnt going back to fire it?
i then mounted it on my BM lower and it fired every round. so it has to be in the MEGA lower i put together. but everything looks like it is together right?

Post a pic and we'll see what we can see.

Since it works on your bushy lower, there's nothing wrong with the upper.

I'd suspect a problem with your hammer, hammer spring or trigger.

seems to be something with the disconector. if i push the trigger forward the hammer pops up ready to fire. seems like something may be a little tight in there. i took it apart and there was nothing wrong put it back together and it did it less but it still gets stuck once in awile.
