I have an old Model 31 12 Ga. and was wondering if anyone could point me to assembly/disassembly instructions for this model. I've contacted the Remington Co. and all they could send me was an exploded view of it. I have taken this apart and re-assembled it twice , but it seems accidental when the bolt and carrier finally got wiggled and turned and cussed at back into place. There is some procedure I am missing, if anyone can help it would be appreciated. Take care, Mikey.
