jlsheer, Try http://www.remington.com/library/downloads/owners_manuals.aspand click on the "Request and Obsolete Owners Manual". I did this yesterday looking for the manual for my 550-1. So far I only received and email saying they have received my request. It's worth a try. Also, there are exploded diagrams avail on the internet, but, I agree with devil dog with being familiar. On another note, you can always use the exploded diagram and try to disassemble / reassemble. Worst case, you will have to take to gunsmith for reassembly.
