Could anybody give me a clue how to get apart a trigger housing on a 472 series Mossberg? I have searched about and the best I have found seems to skip the exact part that I am not able to figure out... Do you have to bite your lip just right? or am I missing something simple? And yes I am releasing pressure on the loading gate, making sure the hammer is not full cock and locked and any other obvious hang-up. I know-get a bigger hammer, but it is for friend so.. It will come up and forward and I have tried the bolt lock up and down still nada.
