Okay tried posting at Troubleshooting and no response.  My bushmaster has developed a problem, the selector switch is stuck in the fire position but the trigger will not release(like it is stuck on safe). I have never had this problem before but have changed two things, put a LMT enhanced bolt on it which I did check the head spacing with a go gauge, and then also changed the pinned CAR stock out for one of the stubby entry model stocks.

I have the rifle opened and do not see anything that might be holding it up.

Well it froze up once got it to release, then happened again after two more mags. Okay, so I need to take it apart and get that out of there.  I will give it a shot, probably end up at teh gunsmith either way.  Thanks for the help guys.
