Disappointment - Midwest Industries Enhanced AR15 Drop-In Trigger

Bought this based on a recommendation. I am sorry to say that this trigger a was a big disappointment. Truly surprised me being that MI is known for quality. First time out to the range, first 1 round land then Click!! the second round misfired. Ejected the round found a very light primer strike. Put magazine back in rack a round Boom!! Yay happy shooter. Pulled trigger for next round, and yup you guessed it Click!! now I am frustrated. Thought maybe it was short stroking. So changed to a lighter Buffer. No change. Finally after more trouble shooting I determined that when the rifle cycled the hammer was not locking and following the BCG back into battery. Well almost it was stopped just shy. The click I was hearing and the light hammer strike on the primer was the hammer being released from the first stage.
