I was nearly finished lapping the hammer hooks on my Poly M14 trigger group when I noticed that the trigger pull suddenly started to feel really rough. After playing with it for a minute trying to figure out what was wrong the trigger became locked completely to the rear and the hammer will not unlock.When I push on the back of the trigger it will move forward but it springs right back once pressure is released. Out of desperation I tried to disassemble the trigger group and was able to get the trigger pin out but nothing else will move. Please tell me this is fixable.
